What Does the Sahara Desert Have to Do with Hurricanes?

This is a post by Charlie Henry, Director, NOAA’s Gulf of Mexico Disaster Response Center and Jeff Medlin, Meteorologist in Charge, National Weather Service Weather Forecast Office Mobile.

What does the Sahara Desert in Africa have to do with hurricanes in the Atlantic, Gulf of Mexico, and Eastern Pacific Ocean? You might think this sounds a little crazy because hurricanes are very wet and deserts are very dry, but if it weren’t for this huge, hot, dry region in North Africa, we would see far fewer hurricanes in the United States.

The Sahara Desert is massive, covering 10 percent of the continent of Africa. It would be the largest desert on Earth, but based strictly on rainfall amounts, the continent of Antarctica qualifies as a desert and is even larger. Still, rainfall in the Sahara is very infrequent; some areas may not get rain for years and the average total rainfall is less than three inches per year. While not the largest or driest of the deserts, the Sahara has a major influence on weather across the Western Hemisphere.

How a Tropical Storm Starts A-Brewin’

The role the Sahara Desert plays in hurricane development is related to the easterly winds (coming from the east) generated from the differences between the hot, dry desert in north Africa and the cooler, wetter, and forested coastal environment directly south and surrounding the Gulf of Guinea in west Africa. The result is a strong area of high altitude winds commonly called the African Easterly Jet. If these winds were constant, we would also experience fewer hurricanes.

However, the African Easterly Jet is unstable, resulting in undulations in a north-south direction, often forming a corresponding north to south trough, or wave, that moves westward off the West African Coast. When these waves of air have enough moisture, lift, and instability, they readily form clusters of thunderstorms, sometimes becoming correlated with a center of air circulation. When this happens, a tropical cyclone may form as the areas of disturbed weather move westward across the Atlantic.

Throughout most of the year, these waves typically form every two to three days in a region near Cape Verde (due west of Africa), but it is the summer to early fall when conditions can become favorable for tropical cyclone development. Not all hurricanes that form in the Atlantic originate near Cape Verde, but this has been the case for most of the major hurricanes that have impacted the continental United States.

Wave of the Future (Weather)

In fact, just such a tropical wave formed off Cape Verde in mid-August of 1992. Up to that point, there had not been any significant tropical cyclone development in the Atlantic that year. However, the wave did intensify into a hurricane, and on August 24 Andrew came ashore in south Florida as a Category 5 hurricane, becoming one of the most costly and destructive natural disasters in U.S. history … until Sandy. Hurricane Sandy, which eventually struck the U.S. east coast as a post-tropical cyclone, also began as a similar tropical wave that formed off the coast of west Africa in October of 2012.

Some of these “waves” drift all the way to the Pacific Ocean by crossing Mexico and Central America. Many of the Eastern Pacific tropical cyclones originate, at least in part, from tropical waves coming off Cape Verde in Africa. Many of these waves traverse the entire Atlantic Ocean without generating storm development until after crossing Central America and entering the warm Eastern Pacific waters. Then, if the conditions are right, tropical cyclone formation is possible there. Hurricane Iselle, which hit the Big Island of Hawaii on August 8, 2014, was likely part of a wave that formed more than 8,000 miles away off of the West Coast of Africa and an example of the far-reaching influence the Sahara Desert has on our planet’s weather.

While these waves with origins in the Sahara Desert might generate numerous thunderstorms and a pattern with the potential for developing into a tropical cyclone, often the conditions are not quite right. Hurricane Cristobal formed from a classic Cape Verde wave last week and currently is churning Atlantic waters, but is not expected to be a threat to the United States. The formation of these disturbances off the West Coast of Africa will remain a potential source of tropical storms through the end of Atlantic hurricane season in late November. Each wave is investigated by the NOAA National Hurricane Center and you can view these active disturbances on their website.

The Sahara Desert and You

When it comes to hurricanes and hurricane preparedness, it’s interesting to know how a desert half a world away can influence the formation of severe weather on our coasts—and even parts of the Pacific Ocean. And no matter where you live, the old rule of planning for the worst and hoping for the best remains the surest way to stay safe.

On the Chesapeake Bay, Overcoming the Unique Challenges of Bringing Restoration to Polluted Military Sites

Transformations are taking place at more than 10 government facilities, mostly owned by the Department of Defense, across the Chesapeake Bay and its tributaries. These properties typically include large, relatively undisturbed natural areas, which often serve as key habitats for endangered fish, birds, and wildlife. Yet the same federal facilities also have become Superfund sites, slated for cleanup under CERCLA, with pollution at levels which threaten the health of humans and the environment.

Yet in spite of some unique challenges, these areas are being cleaned up and restored to become healthy places for all once more. Success has stemmed largely from two critical pieces of the process: collaborating closely among numerous government agencies and incorporating restoration into the process as early and often as possible.

According to Paula Gilbertson of the U.S. Navy, “The close partnership among the many federal and state agencies involved has provided a framework for success. Great things can happen when people work together toward a common goal.”

Moving Past the Past

Past activities leading to pollution at U.S. Army, Air Force, and Navy sites on Chesapeake Bay were many and varied, and included: incineration, landfilling, ship and airplane repair and maintenance, military testing, and pesticide and munitions disposal. As a result, beginning in the 1980s, entire facilities along the bay became Superfund sites and listed for priority cleanup.

Typically during the Superfund process, the party responsible for polluting has to work with the U.S. Environmental Protection Agency (EPA), which leads the cleanup, and other state and federal agencies—known as trustees—which represent affected public lands and waters.

But in these cases, the Department of Defense has to play multiple roles: trustee of natural resources on the property, entity responsible for contamination, and lead cleanup agency. In addition, the EPA still oversees the effectiveness of the Superfund cleanup, and the military branches at each site still have to coordinate with the other trustees: NOAA, the U.S. Fish and Wildlife Service, and state agencies.

NOAA and the Fish and Wildlife Service also are part of a special technical group run by the EPA (the Biological Technical Assistance Group, or BTAG), which coordinates trustee participation and offers scientific review throughout the ecological risk assessment and cleanup process at each site.

According to Bruce Pluta, coordinator of the EPA BTAG, “The collaborative efforts of the EPA Project Team, including the BTAG, and our partners at the Department of Defense have resulted in model projects which integrate remediation and ecological restoration.”

Working Together for the Future

What does not change during this process is that the trustees are working to protect and restore the “trust resources,” including lands, waters, birds, fish, and wildlife affected by contamination coming from these military sites. This can include natural areas adjacent to the sites and the animals that could migrate onto the federal properties, such as striped bass, herring, blue crabs, eagles, and herons.

Other important differences exist governing how all these government entities work together in the Superfund cleanup process. For example, NOAA often works to evaluate ecological risks and determine environmental injuries resulting from hazardous material releases at Superfund sites. Then we implement restoration projects to compensate for the injuries to coastal and marine natural resources and the benefits they provide to the public. This is the Natural Resource Damage Assessment process. NOAA seeks legal damages (payment) or works with those responsible for the pollution through cooperative agreements to restore, replace, or acquire the equivalent natural resources.

As federal trustees, we are significantly limited in our ability to conduct a formal damage assessment against a fellow federal agency doing cleanup because we are both trustees of the affected natural resources. However, all federal and state trustees can work together with EPA to protect the lands, waters, and living things during cleanup, maximize the potential for restoration at each site, and develop measures to ensure both environmental recovery and resilience.

“By considering restoration early in the process and getting input from natural resource managers, many simple, common sense measures are being incorporated that benefit ecosystems, reduce overall costs, and improve the effectiveness of the cleanup,” says Simeon Hahn of NOAA.

Overcoming Challenges

Having so many government agencies involved in overlapping but distinct roles requires a great deal of collaboration and communication. This became clear early in the process if each case were to achieve multiple objectives:

  • Cleaning up the military sites and returning the lands and waters to productive uses.
  • Performing cleanups using environmentally friendly strategies to remove, recycle, and reuse materials while also addressing climate resiliency.
  • Protecting and restoring natural resources.
  • Accomplishing everything within a reasonable budget and timeframe.

Despite the many challenges, the process of cleaning up and restoring these contaminated military facilities has been going well. EPA, the Department of Defense, and fellow trustees have collaborated to protect and restore affected natural resources while also helping adapt these areas to the threats and impacts of climate change. By integrating restoration into cleanup planning early and often, we have made significant progress toward a healthier Chesapeake Bay—at lower costs and in less time.

Over the coming months, we will be sharing more about these successes here on the blog. We will recount the removal and recycling of thousands of tons of concrete; the restoration of hundreds of acres of wetlands, shorelines, creeks, and forested areas; and the revitalization of numerous acres of land contributing to benefits such as natural defenses for coastal communities. Stay tuned!

With NOAA as a Model, India Maps Coastal Sensitivity to Oil Spills

This is a post by Vicki Loe and Jill Petersen of NOAA’s Office of Response and Restoration.

They say that imitation is the sincerest form of flattery, which is why we were thrilled to hear about recent efforts in India to mirror one of NOAA’s key oil spill planning tools, Environmental Sensitivity Index maps. A recent Times of India article alerted us to a pilot study led by scientists at the National Institute of Oceanography in India, which used our Environmental Sensitivity Index (ESI) shoreline classifications to map seven talukas, or coastal administrative divisions in India. Amid the estuaries mapped along India’s west coast, one of the dominant shoreline types is mangroves, which are a preferred habitat for many migratory birds as well as other species sensitive to oil.

Traditional ESI data categorize both the marine and coastal environments as well as their wildlife based on sensitivity to spilled oil. There are three main components: shoreline habitats (as was mapped in the Indian project), sensitive animals and plants, and human-use resources. The shoreline and intertidal zones are ranked based on their vulnerability to oil, which is determined by:

  • Shoreline type (such as fine-grained sandy beach or tidal flats).
  • Exposure to wave and tidal energy (protected vs. exposed to waves).
  • Biological productivity and sensitivity (How many plants and animals live there? Which ones?).
  • Ease of cleanup after a spill (For example, are there roads to access the area?).

The biology data available in ESI maps focus on threatened and endangered species, areas of high concentration, and areas where sensitive life stages (such as when nesting) may occur. Human use resources mapped include managed areas (parks, refuges, critical habitats, etc.) and resources that may be impacted by oiling or clean-up, such as beaches, archaeological sites, or marinas.

Many countries have adapted the ESI data standards developed and published by NOAA. India developed their ESI product independently, based on these standards. In other cases, researchers from around the world have come across ESI products and contacted NOAA for advice in developing their own ESI maps and data. In the recent past, Jill Petersen, the NOAA ESI Program Manager, has worked with scientists who have visited from Spain, Portugal, and Italy.

By publishing our data standards, we share information which enables states and countries to develop ESI maps and data independently while adhering to formats that have evolved and stood the test of time over many years. In addition to mapping the entire U.S. coast and territories, NOAA has conducted some of our own international mapping of ESIs. In the wake of Hurricane Mitch in 1998, we mapped the coastal natural resources in the affected areas of Nicaragua, Honduras, and Ecuador.

Currently, we are developing new ESI products for the north and mid-Atlantic coasts of the United States, many areas of which were altered by Hurricane Sandy in 2012. The new maps will provide a comprehensive and up-to-date picture of vulnerable shorelines, wildlife habitats, and key resources humans use. Having this information readily available will enable responders and planners to quickly make informed decisions in the event of a future oil spill or natural disaster.

You already know how much the ocean does for you and how important it is to both celebrate and protect it. The U.S. Department of State also realizes this importance and, as a result, is hosting the Our Ocean Conference in Washington, DC from June 16–17, 2014. According to ourocean2014.state.gov:

We will bring together individuals, experts, practitioners, advocates, lawmakers, and the international ocean and foreign policy communities to gather lessons learned, share the best science, offer unique perspectives, and demonstrate effective actions. We aim to chart a way forward, working individually and together, to protect “Our Ocean.”

Watch a message about the conference and find out how you can help from Secretary of State John Kerry:

Marine pollution, a topic NOAA’s Office of Response and Restoration is very concerned about, is one of three core areas the conference aims to address, along with ocean acidification and sustainable fisheries. When a plastic bag or cigarette butt blows into a river, it can end up flowing to the ocean, where it endangers marine life. The problem is global, but mitigation is local. It’s in our hands to reduce marine debris—our trash in our ocean—at its source. Learn more about the debris filling our seas by reading about the challenges and solutions in this Our Ocean conference document [PDF], by visiting marinedebris.noaa.gov, and by watching the video below:

On the Our Ocean 2014 website, you also can submit your own pledge to protect the ocean, whether that means volunteering to clean up a beach or tracing the sustainability of the seafood you eat. Plus, you can show your support for the ocean by sharing a photo that inspires your dedication to our ocean. (If you’re looking for inspiration, try the images in our Flickr stream.) The State Department says all you have to do to participate is:

Post your photo to your favorite social media platform using the hashtag #OurOcean2014 or add it to the OurOcean2014 group on Flickr.  We will be keeping an eye out for photos using the hashtag and will choose some of the photos to be featured at the Our Ocean conference in Washington on June 16-17.

Check out the program schedule and watch the conference streaming live starting at 9:30 a.m. Eastern on Monday and Tuesday at state.gov/ourocean.

April Showers Bring … Marine Debris to Pacific Northwest Beaches?

This is a post by Amy MacFadyen, oceanographer and modeler in the Office of Response and Restoration’s Emergency Response Division.

Over the last few weeks, emergency managers in coastal Washington and Oregon have noted an increase in the marine debris arriving on our beaches. Of particular note, numerous skiffs potentially originating from the Japan tsunami in March 2011 have washed up. Four of these boats arrived in Washington over the Memorial Day weekend alone.

This seasonal arrival of marine debris—ranging from small boats and fishing floats to household cleaner bottles and sports balls—on West Coast shores seems to be lasting longer into the spring than last year. As a result, coastal managers dealing with the large volume of debris on their beaches are wondering if the end is in sight.

As an oceanographer at NOAA, I have been trying to answer this question by examining how patterns of wind and currents in the North Pacific Ocean change with the seasons and what that means for marine debris showing up on Pacific Northwest beaches.

What Does the Weather Have to Do with It?

Beachcombers know the best time to find treasure on the Pacific Northwest coast is often after winter storms. Winter in this region is characterized by frequent rainfall (hence, Seattle’s rainy reputation) and winds blowing up the coast from the south or southwest. These winds push water onshore and cause what oceanographers call “downwelling”—a time of lower growth and reproduction for marine life because offshore ocean waters with fewer nutrients are brought towards the coast. These conditions are also good for bringing marine debris from out in the ocean onto the beach, as was the case for this giant Japanese dock that came ashore in December 2012.

These winter storms are associated with the weather phenomenon known as the “Aleutian Low,” a low pressure system of air rotating counter-clockwise, which is usually located near Alaska’s Aleutian Islands. In winter, the Aleutian Low intensifies and moves southward from Alaska, bringing wind and rain to the Pacific Northwest. During late spring, the Aleutian Low retreats to the northwest and becomes less intense. Around the same time, a high pressure system located off California known as the “North Pacific High” advances north up the West Coast, generating drier summer weather and winds from the northwest.

This summer change to winds coming from the northwest also brings a transition from “downwelling” to “upwelling” conditions in the ocean. Upwelling occurs when surface water near the shore is moved offshore and replaced by nutrient-rich water moving to the surface from the ocean depths, which fuels an increase in growth and reproduction of marine life.

The switch from a winter downwelling state to a summer upwelling state is known as the “spring transition” and can occur anytime between March and June. Oceanographers and fisheries managers are often particularly interested in the timing of this spring transition because, in general, the earlier the transition occurs, the greater the ecosystem productivity will be that year—see what this means for Pacific Northwest salmon. As we have seen this spring, the timing may also affect the volume of marine debris reaching Pacific Northwest beaches.

Why Is More Marine Debris Washing up This Year?

NOAA has been involved in modeling the movement of marine debris generated by the March 2011 Japan tsunami for several years. We began this modeling to answer questions about when the tsunami debris would first reach the West Coast of the United States and which regions might be impacted. The various types of debris are modeled as “particles” originating in the coastal waters of Japan, which are moved under the influence of winds and ocean currents. For more details on the modeling, visit the NOAA Marine Debris website.

The estimated arrival of modeled "particles" (representing Japanese tsunami marine debris) on the West Coast of the United States between May 2011 and May 2014.

The figure here shows the percentage of particles representing Japan tsunami debris reaching the shores of Washington and Oregon over the last two years. The first of the model’s particles reached this region’s shores in late fall and early winter of 2011–2012. This is consistent with the first observations of tsunami debris reaching the coast, which were primarily light, buoyant objects such as large plastic floats, which “feel” the winds more than objects that float lower in the water, and hence move faster. The largest increases in model particles reaching the Pacific Northwest occur in late winter and spring (the big jumps in vertical height on the graph). After the spring transition and the switch to predominantly northwesterly winds and upwelling conditions, very few particles come ashore (where the graph flattens off).

Interestingly, the model shows many fewer particles came ashore in the spring of 2013 than in the other two years. This may be related to the timing of the spring transition. According to researchers at Oregon State University, the transition to summer’s upwelling conditions occurred approximately one month earlier in 2013 (early April). Their timing of the spring transition for the past three years, estimated using a time series of wind measured offshore of Newport, Oregon, is shown by the black vertical lines in the figure.

The good news for coastal managers—and those of us who enjoy clean beaches—is that according to this indicator, we are finally transitioning from one of the soggiest springs on record into the upwelling season. This should soon bring a drop in the volume of marine debris on our beaches, hopefully along with some sunny skies to get out there and enjoy our beautiful Pacific Northwest coast.

What Have We Done for Endangered Species Lately?

The brown pelican, a successfully recovered species, was removed from the Endangered Species List in 2009. (U.S. Fish and Wildlife Service)

Endangered species have a tough time of it. These plants and animals have been trampled, hunted, contaminated, and pushed out of their homes by humans to the point that their very existence on this planet becomes dangerously uncertain. In the United States, this is when the federal government steps in to list a species as threatened or endangered under the 1973 Endangered Species Act.

Over 40 years later, this critical piece of legislation has had many successes in protecting native animals and plants and the natural areas where they live—perhaps most notably bringing back the national symbol, the bald eagle, from the brink of extinction. Yet with more than 1,500 types of animals and plants remaining threatened or endangered in the United States, we still have more work to do.

On May 16, 2014, we’re going to take the time to recognize this very important national conservation effort by celebrating Endangered Species Day and the many ways, big and small, each of us can help save our nation’s incredible array of plants and animals from extinction—like the now-recovered brown pelican!

Tools for Protecting Species During Oil Spills

So, what has NOAA been doing for endangered species? One example is the Office of Response and Restoration’s special data mapping tools that come into play during oil spills.

When an oil spill occurs along the coast, one priority for our office is identifying whether any threatened or endangered species live in the area near the spill. The responders dealing with the spill have to take into account factors such as what time of year these protected species are breeding or how they might come into contact with spilled oil or the response. This means knowing whether young Chinook salmon may be migrating out to sea through an estuary where a ship may have accidentally discharged fuel. Or knowing if the beaches where spill responders need to clean up oil are also important nesting grounds for a shorebird such as the piping plover.

Our biologists and ecologists help provide this kind of information during an oil spill response, but our office also produces tools to organize and display all of this information for both NOAA and oil spill planners and responders outside our agency. One of these tools is NOAA’s Environmental Sensitivity Index (ESI) maps. These maps characterize coastal environments and wildlife based on their sensitivity to spilled oil. The main components of these maps are sensitive wildlife, shoreline habitats, and the resources people use there, such as a fishery or recreational beach.

A related Geographic Information Systems (GIS) tool, the Threatened and Endangered Species Geodatabases, make up a subset of the original ESI data from our maps. These data focus on the coastal species and habitats that are federally and/or state listed as endangered, threatened, protected, or as a species of concern. These databases offer a more user-friendly option to access some of the most critical biological information for a region.

In the example below, you see a map of Great South Bay from the Long Island ESI atlas. The colored shapes (red, blue, green, and maroon) indicate where the piping plover, shortnose sturgeon, eastern mud turtle, and seabeach amaranth occur in June.

Using the Threatened and Endangered Species Geodatabases allows oil spill planners and responders to easily gather complex information for a region, such as groupings of species with similar habitat preferences and feeding styles, threatened and endangered status, concentration, and life history summaries. This tool also features the ability to search for presence of a species in a particular month or season. You can take a look at these data, pulled from our many state and federal partners, for anywhere in the United States using this online map application.
