Paper on how tropical cyclones in shear intensify published in Geophysical Research Letters

Summary: Tropical cyclones (TCs) are made up of thunderstorms (what we call convection), and these storms have strong winds moving up and down (what we call up- and downdrafts). Dry air enhances evaporative cooling (the same process that cools people when they sweat) from convective downdrafts, reducing the temperature and humidity in low levels; this … Continue reading Paper on how tropical cyclones in shear intensify published in Geophysical Research Letters

Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from … Continue reading Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review
