ATOC 1050 Lecture 24: Ch. 11 Notes
Document Summary
Only small seasonal changes in the weather. Very little pressure variation often use streamlines instead of pressure contours to see areas of convergence and divergence. Hurricane katrina over the gulf of mexico on august 28th, 2005. A large quantity of warm, moist air. A continuous supply of warm, moist air. Light winds aloft: most hurricanes develop in late summer when ocean waters have reached sufficient temperatures of, 80 degrees fahrenheit, to provide heat and moisture in the atmosphere. Warm ocean water: hurricanes need warm ocean temperatures (at least 80 degrees fahrenheit) to form, how does this happen, stages of hurricane: Easterly waves: tropical depression, as the pressure falls, the thunderstorms grow bigger and start to organize. As air flows toward the low pressure zone, it picks up more energy from the warm sea surface and also starts to rotate due to the coriolis force.
