Over the years discussed since the Revolutionary War there have been all kinds of hurricane seasons, but, the general trend is obvious.
This is a study done of North America and drought. Drought and hurricanes are related. The worse the drought the less hurricanes because there is far less water vapor in the troposphere to generate the storms.
Click on link above and experience the devastation of 2005 years of ever increasing drought. As you watch it's progression realize it starts with desert in the West but spreads throughout the West. Each drought season is actually building the next drought season as biota dies off with each passing drought and the trees are less hardy.
Also realize the intrusion of an every growing population in the USA and it's destruction by timber and replacing biota with concrete and macadem.
