Behind the 2015 Atlantic Hurricane Season: Wind Shear & Tropical Cyclones

Wind Shear
No Wind Shear

In the presence of vertical wind shear, a storm’s core structure will be tilted in relationship to the wind shear. This tilting will disrupt the flow of heat and moisture which inhibits the storm from developing and becoming stronger.

With the 2015 Atlantic hurricane season underway, researchers are pointing to the strong presence of El Niño as the major driver suppressing the development of tropical cyclones in the Atlantic basin. But what specific conditions are associated with El Niño that lead to a less than ideal environment for tropical cyclone development? Through research and observation, hurricane researchers know strong environmental wind shear is a major factor affecting potential hurricane development and growth. This hurricane season, AOML researchers are delving further into the relationship between wind shear and tropical cyclones.

What is wind shear?

Wind shear is the variation of the wind’s speed or direction over a short distance within the atmosphere. For tropical cyclones, wind shear is important primarily in the vertical direction, as these storms occupy a large vertical slice of the atmosphere from sea level to the top of the troposphere, which extends up to about 40,000 feet altitude in the tropics in summer.

How does wind shear affect tropical cyclone development?

Tropical weather systems are vulnerable to changes in the broader atmosphere surrounding them; often influenced by large features such as areas of high and low pressure, and fronts. If there’s too much wind, these weather systems have trouble organizing and developing into a tropical cyclone. As a tropical system forms, heavy thunderstorms build near the center. Given the right environment, these systems can eventually begin turning counter-clockwise (or cyclonically) in the northern hemisphere. With little to no wind shear, the turning within the tropical system is uniform and the storm becomes vertically aligned, helping to keep it intact and, likely, strengthening.

The most favorable condition for tropical cyclone development is the absence of wind shear. When wind shear is present, however, a storm’s core structure becomes vertically tilted in relationship to the wind shear, disrupting the flow of heat and moisture. Tropical cyclones are heat engines powered by the massive heat release associated with water vapor condensing into liquid water. Vertically-tilted systems are less efficient at drawing in warm and moist air from the surrounding ocean and will be less likely to develop and strengthen.

How does El Niño affect the presence or absence of wind shear?

El Niño is a climate phenomenon driven by above average ocean temperatures in the central and eastern tropical Pacific. While that warmth helps boost Pacific storm activity, the extra heat transferred to the atmosphere leads to a domino effect, altering climate around the globe.

Specifically, the instability over the warm equatorial Pacific during El Niño creates changes in the jet stream over the Northern Hemisphere, resulting in decreased wind shear in the Pacific and increased wind shear across much of the Caribbean and Atlantic. El Niño also increases the atmospheric stability, or resistance of the atmosphere to vertical motion, in the Atlantic basin, which suppresses hurricane activity.

Can a storm persist despite the existence of wind shear?

AOML researchers are focusing on particular characteristics of developed tropical cyclones that enable them to persist despite increased levels of wind shear. The theoretical work focuses mainly on how a tropical cyclone’s wind structure is disrupted by wind shear.

Using a simple mathematical model, researchers can estimate the degree to which the center of the storm becomes vertically tilted based on the cloudiness within the eyewall, as well as the structure of the wind outside the eyewall. By modeling the development of storm tilt, a better understanding of a tropical cyclone’s behavior is gained in the presence and absence of wind shear.

Results suggest that tropical cyclones are more likely to resist disruption by vertical wind shear when clouds cover a large portion of the eyewall and when winds decrease less rapidly from the eye. These model simulations show promise in understanding the fundamental physical processes driving intensity and structural changes of tropical cyclones due to environmental factors.

Model results suggest certain features such as cloudiness within the eyewall as well as the structure of the wind outside the eyewall may determine a storm’s level of resistance to wind shear.

A Doppler wind lidar instrument added to NOAA’s hurricane hunter aircraft this season will assist AOML researchers in collecting observational data to better understand the wind environment around tropical cyclones. The lidar instrument is used to collect, process, and transmit atmospheric data from within a hurricane, enabling NOAA to sample the winds inside the eyewall of storms. By leveraging observational expertise and new data combined with modeling, AOML researchers hope to learn more about the wind environment and the interaction between wind shear and tropical cyclones, allowing them to better predict a hurricane’s future activity and intensity.

AOML Enlists Citizen Scientists for International Ocean Sampling Day 2015

 

Researchers with AOML’s Environmental Microbiology Lab joined a global effort to sample the smallest members of the ocean ecosystem on June 21 during International Ocean Sampling Day. Organized and led by the European Union’s MicroB3 organization and the Ocean Sampling Day Consortium, Ocean Sampling Day (OSD) is a simultaneous sampling campaign of the world’s oceans and coastal waters. These cumulative samples, related in time, space and environmental parameters, contribute to determine a baseline of global marine biodiversity and functions on the molecular level.

What are scientists looking for?

The organisms of scientific interest for the OSD campaign include microscopic Bacteria, Archaea, Fungi, Protists and viruses, collectively known as microbes. Microbes make up 98 percent of the biomass in Earth’s oceans and are responsible for most of the biological activity that takes place within it. Microbes are found everywhere, from the ocean surface to deep within rocks beneath the ocean floor. They are pervasive and can evolve rapidly in response to changes in the environment. In fact, many scientists consider microbes to be a “canary in the coal mine”, signaling local and global changes in the oceans. It is, therefore, important to acquire information from across the globe on this vast community of organisms, against which future changes can be observed and measured.

2014: The first global OSD effort

During the 2014 Ocean Sampling Day event, over 180 scientific teams participated from all continents ranging from subtropical waters in the Caribbean to extreme environments in the Antarctic Ocean. On this day, more than 600 people all around the world took water samples from the ocean in order to identify the microbes within. Scientists used the data collected to support projects focusing on environmental microbiology parameters that describe the relationship between marine microbes and human health and the health of our local marine ecosystems. This data will also provide insights to the ocean economy through the identification of novel, ocean-derived biotechnologies.

Where are AOML scientists sampling?

This year, AOML will coordinate and sample ten OSD sites across the country. In addition to the 2014 sites in the Florida Keys, Ft. Lauderdale, Tampa Bay, La Jolla, California, and Horn Island, Mississippi, AOML will coordinate five new sites spread across the Florida peninsula from Pensacola to Miami. Sampling sites are expected to be monitored long-term as part of the international Genomic Observatories Network and the resulting database will be accessible to the public.

 

MyOSD: The citizen scientist component

 OSD organizers have amended the citizen science component for this year’s event, allowing individuals from all over the globe to collect samples in their backyard using handy sampling kits. This component, called MyOSD, gives individuals the chance to help scientists unravel the mysteries of the marine microbial world by collecting important environmental data such as latitude, longitude, temperature, salinity, pH and wind speed.

AOML has coordinated and provided kits to a number of citizen science groups in Florida and California, including organized youth groups, citizen science organizations, educational centers, and outreach groups. Samples collected will represent a variety of different marine ecosystems including the open ocean, beaches, coral reefs, and estuaries.

 

We are excited to be working with a number of citizen scientists this year to expand our sampling effort and help contribute to our understanding of the ocean’s biodiversity said AOML. “

A baseline for the future

With the combined effort of researchers and citizen scientists, OSD 2015 continued the initiative to collect and share crucial information that can be used as a reference for generations of experiments to follow in the coming decades. Additionally, the data analysis procedures being developed for OSD are driving the field forward, but it is clear that much remains to be discovered about the microbial world. Scientists hope that such large-scale projects that provide an “ecological snapshot” become increasingly more common as they are essential for understanding the complexity of Earth’s systems.

AOML Scientists Featured in Special Women’s History Month Issue of Oceanography Magazine

Women’s History Month is celebrated annually in March and pays tribute to the generations of women whose contributions made a historical impact on society. It is also a month to honor women who are currently working hard to make positive innovations and impressions on the world.

The Oceanography Society published a special issue of their magazine for 2015 Women’s History Month entitled “Women in Oceanography: a decade Later,” which features four of AOML’s female oceanographers.

The Oceanography Society’s feature includes statistics, women’s program descriptions, and one-page autobiographical sketches written by women oceanographers. It is the sequel to their first “Women in Oceanography” issue, released in 2005, dedicated to exploring why men outnumbered women at higher levels of the field.

This issue evaluates progresses made in retaining women in the oceanography field over the past decade. The article included over 200 autobiographical sketches, which highlighted AOML’s Libby (Elizabeth) Johns, Renellys C. Perez, Claudia Schmid, and Silvia L. Garzoli.

Click below to find out more about each scientist.

Libby (Elizabeth) Johns Oceanographer for the Physical Oceanography Division at AOML

Over the past decade, Libby has continued with her research in south Florida coastal oceanography and broadened her interests to include fisheries oceanography. As a woman in her chosen field, Libby faced a few challenges. First and foremost, the challenge of being a wonderful mother while continuing to excel at her professional career had her constantly adapting to life’s changes. Another challenge Libby faced was transitioning from strictly physical oceanography to interdisciplinary, applied oceanography.  Libby’s advice; “Do not settle for the status quo, but instead constantly evaluate the various parts of a happy and successful life so every aspect can compliment each other.”

Claudia Schmid Oceanographer for the Physical Oceanography Division at AOML

A combined love of the ocean, math and physics brought Claudia to the field of oceanography. Growing up, she spent summers mostly in or on the waters of the Mediterranean. Through her research projects, she achieved global data coverage with regular sampling. For Claudia this was a dream come true. It inspired her to become more involved with data management, co-principal investigator for the Argo project, and join the Prediction and Research Moored Array in the Tropical Atlantic project.

Silvia L. Garzoli Chief Scientists Emeritus at AOML & CIMAS

Over the past 10 years, Silvia transitioned through many life changes. From director of the Physical Oceanography Division (PhOD) at NOAA’s AOML, to Chief Scientist of AOML, to retirement and a part-time scientific position, Silvia witnessed positive changes in the challenges women in science face. When she was PhOD’s director she faced administrative and management challenges, including being a “woman boss,” During her time as director, PhOD greatly benefitted and received excellent reviews after an intensive external review process. Now Silvia works part time as a scientist in order to direct her energy toward writing papers and experiencing extended research cruises. Her advice; “Change is good. It is difficult, and scary, but good!”

Renellys C. Perez Associate Scientist for CIMAS and AOML

Renellys’s love of the ocean brought her to her current research, which is focused on developing a better understanding of ocean currents and their roles in ocean-atmospheric heat exchange. Her investigations require collaboration with other researchers around the world, which allows her to travel and conduct research at sea. This can sometimes be challenging because it involves time spent away from her husband and daughter. Being a woman in science required that Renellys be able to balance family and a career.  Renellys also had to overcome learning how to navigate the US science funding system. She plans on using the multitasking skills she developed in her family life and putting them to use at work, funding multiple projects simultaneously.
