A hurricane needs humidity to develop. Humidity is the amount of  water in the air. A hurricane starts off as a series of  thunderstorms which intensify as it moves over the â¦ warm humid sea.  The humidity continues to grow over the sea. Any sort of decrease  or increase in humidity can change the strength of a hurricane.
If all of the pre-conditions are met, hurricane formation then becomes possible. There are several types of atmospheric disturbances that can cause a hurricane to develop. The most common mechanism to cause hurricanes to form is the monsoon trough. This is an extension of the Inter-Tropical Convergence Zone where cyclonic spin has developed.
