Frequency of tropical cyclones
WebA tropical depression is a relatively weak tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less, and a tropical storm has maximum sustained winds of 39–73 mph (34–63 knots).

WebSubscribing to Knutson et al.’s theories, the peak wind speed of tropical cyclones should increase by about 5% for every 1 ºC increase in tropical ocean temperature. Since there has only been a 0.5ºC increase observed, these peak wind speeds should have only increased by 2-3%, and the PD by 6-9%, and the PDI by 8-12%. http://courses.geo.utexas.edu/courses/387H/Lectures/The%20Effects%20of%20Global%20Warming%20on%20Tropical%20Cyclones.doc
