Analyzing Tropical Waves Using the Parallel Ensemble Empirical Model Decomposition Method: Preliminary Results from Hurricane Sandy

EarthzineDecember 2, 2013ESTO Showcase 2013, Original

To reveal multiscale processes from high-resolution, multidimensional Earth science data, we have developed the parallel version of the ensemble empirical model decomposition (PEEMD) method with a three-level parallelism. In this study, we illustrate the performance of the PEEMD in extracting tropical wave components from idealized tropical wave solutions and large-scale environmental flows associated with Hurricane Sandy.

Originally Published by ENS – Strengthening into a hurricane just after noon on Tuesday, Isaac made landfall in far southeastern Louisiana in Plaquemines Parish at 6:45 pm local time. The hurricane struck nearly seven years to the day after Hurricane Katrina devastated New Orleans and the Gulf coast in 2005.

It is important for people to be aware of the natural disasters they might face in order to respond and avoid major consequences. It is necessary to have correct information to analyze the impact of a disaster, in this case, a hurricane.

NASA's Hurricane Webpage: A Resource for Worldwide Tropical Cyclones

This 3-D image of Hurricane Igor's cloud heights and rainfall from NASA TRMM data shows a large area of heavy rainfall (falling at about 2 inches per hour), shown here in red on Sept. 15, 2010, at 0353 UTC. The yellow and green areas indicate moderate rainfall between 0.78 to 1.57 inches per hour. The image reveals that Igor's eye was still very distinct but the southwestern portion of the eye wall had eroded. It was located about 440 miles east-northeast of the Northern Leeward Islands in the Atlantic Ocean at this time. Credit: Credit: NASA/SSAI, Hal Pierce

NASA’s Hurricane Webpage is a resource for meteorologists and weather fans, with updates on tropical cyclones happening around the world, along with satellite images, the latest research, animations, educational tools, scientist profiles, satellite information and historic storm information.
