Paper on a new dropwindsonde that measures sea surface temperature released online in the Journal of Atmospheric and Oceanic Technology

Warm water provides the energy for tropical cyclones to form and intensify, and knowing the temperature of the water is important in predicting how strong a hurricane will become. Dropwindsondes are instruments that measure air temperature, moisture, pressure, and wind velocity as they fall toward the ocean after release from Hurricane Hunter aircraft, but they […]

Paper on the types and sizes of ice particles in hurricanes released online in the Journal of Applied Meteorology and Climatology

Many people have experienced the heavy rain and warm, moist air when hurricanes reach land. But several miles above the ground, where the air is very cold, hurricane clouds are made up of snowflakes and tiny ice particles called ice crystals. The computers that scientists use to forecast where hurricanes will go and how strong […]

Paper on the Coyote unmanned aircraft system in Hurricane Edouard published in Earth and Space Science

This was the first successful launch of an unmanned aircraft system into a mature hurricane from a Hurricane Hunter aircraft. This so-called Coyote is a 13-pound drone with a 5-foot wingspan that measures pressure, temperature, humidity, and wind speed and direction.    Important Conclusions: Data from the Coyote compared very well with other observations […]

Paper on Colorado hailstorms published in Weather and Forecasting

Summary: Thunderstorms that result in deep hail on the ground can threaten life and property. Previous such storms in the Denver area caused hail to pile up to two feet deep in 30 minutes and closed roads, damaged aircraft, and required swift water rescues due to flooding from rain and melting hail. Because snowplows and […]
