HURRICANE (TYPHOON) DEVELOPMENT CONDITIONS FOR HURRICANE DEVELOPMENT: 1. OCEAN TEMPERATURE MUST EXCEED 27EC WARM WATER PROVIDES THE ENERGY SOURCE FOR THE SUSTENANCE OF THE HURRICANE 2. LATITUDE MUST BE > 4 E N BUT < 15 E (WATER IS TOO COLD > 15 E) 3. WARM WATER MUST REACH DEPTHS OF ~ 100 M I.E. ENERGY STORED NEEDED TO SUSTAIN STORM

Atlantic hurricanes often develop off Cape Verde or in Caribbean or Gulf of Mexico. Typhoons are Pacific Hurricanes.

HURRICANES ARE A HEAT ENGINE, TRANSFERRING HEAT FROM THE OCEAN TO THE ATMOSPHERE. HEAT COMES IN VIA WARM WATER AND IS EXHAUSTED OUT THE TOP INTO THE UPPER TROPOSPHERE AND LOWER STRATOSPHERE. SOME AIR SINKS INTO THE EYE OF THE STORM CREATING CLEAR AND CALM CONDITIONS.
