Paper on the types and sizes of ice particles in hurricanes published 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 …
