A-Train-Based Analysis of Frontal Cloud and Precipitation Structures: A Case Study
The week of Thanksgiving Day in 2006, an extratropical cyclone formed off the coast of Florida and slowly travelled along the eastern seaboard for approximately five days. Copious warm conveyor belt transport of water vapor resulted in coastal flooding in the Carolinas and over an inch of snow in portions of Georgia and South Carolina. Multiple overpasses of this long lived and nearly stationary cyclone were obtained from NASA's Earth Observing System Afternoon-Train (A-Train) Satellite constellation. When combined with winds from an operational numerical analysis, this project was able to use data from the A-Train to observe and understand the evolution of the warm conveyor belt cloud and precipitation structure. Our results demonstrate the value of an analysis that combines satellite and numerical model data, providing insight into the relationships between mesoscale cloud and precipitation features and cyclone scale dynamics and thermodynamic environment.
