Paper examining the region closest to the ocean surface in hurricanes and typhoons published in the Journal of Geophysical Research

Posted on May 15, 2015 by

Global Positioning System dropwindsondes are released by Hurricane Hunter Aircraft to measure temperature, pressure, humidity, and wind speeds. Dropwindsonde data show what the wind, temperature and moisture are like nearest the ocean surface. In this study, hurricanes in the Atlantic … Continue reading →
