Review of extratropical transition released online in Monthly Weather Review

Summary: When tropical cyclones move out of the tropics toward the poles, they reach areas where fronts exist and where the ocean, whose warm water fuels tropical storms, is relatively cool. When this happens, the storms go through extratropical transition (ET) and become like other storms in the mid latitudes. The storms can cause catastrophic […]

Paper on accounting for the location of dropwindsondes during measurements published in the Journal of Atmospheric and Oceanic Technology

Summary: Hurricane Hunter aircraft have been releasing instruments called dropwindsondes to measure pressure, temperature, moisture, and wind speed and direction in hurricanes for two decades. Data from dropwindsondes released near the storms have led to better forecasts of where they will go, but improvements to forecasts of how strong they will get have lagged. Part […]
