PHY 118 Final Study Guide: Chapter 11 I. Hurricanes: a. Most deadly hurricane = Galveston, 1990. 8000 deaths. b. Most form between 5 – 20 degrees latitude over all tropical oceans except the S. Atlantic + S. Pacific i. Weak coriolis effect at equator doesn’t generate high enough wind speeds ii. Ocean water temp above 20 degrees latitude is too low to form c. Most form in late summer when ocean waters reach 80 F or higher d. North Atlantic has greatest number e. Typhoons = W. Pacific f. Cyclones = S. E. Pacific g. Fuel for survival = warm, moist air from oceans of 80 F or higher + release of latent heat through condensation h. Sometimes produce tornadoes i. Profile: i. Sustained winds of at 74 mph ii. 100 - 930 miles in diameter iii. Rotary circulation iv. Pressure drops from outer edge to the center v. Eye Wall – the doughnut shaped wall of intense convective activity surrounding the center of the storm 1. Highest wind speeds 2. Heaviest precipitation vi. Outward flow at top, providing room for inward flow at surface vii. Eye – Very center of storm, zone of relative calm 1. Subsiding air warms by compression, warmest part of storm 2. Weakest winds 3. Lowest pressure j. Formation:
