on maps, you can look at…1.Wind direction2.Wind speed3.Temperature4.Dewpoint temperature5.Pressure tendency6.“Weather” (showers, t-storms)•3 trigger mechanisms for tropical thunderstorms1.Inter-Tropical Convergence Zone2.Easterly waves3.Old mid-latitude fronts•4 characteristics of the hurricane environment (requirements)1.Sea surface temperature > 80°F2.Deep (> 200ft) layer of warm water3.Weak wind shear4.Location at least 5°N or S•Wind shear is bad for hurricanes because it spreads out the clouds, causing latent heat and surface pressure to drop (El Niño Years=windy).
•The coriolis force is important for storm rotation. At the equator, this force is equal to zero. This is why hurricanes form anywhere past 5 degrees above or below the equator, but not on it.•4 destructive forces of a hurricane1.Wind2.Heavy rain3.Storm surge4.Waves•Aircrafts that fly into the eyes of hurricanes can forecast the intensity and movement of the storm.•The primary reason for unpredicted behavior of hurricanes is poor initialization of the models due to the lack of observations available throughout the tropics.•Types of drought:1.Meteorological Drought: an unusually long period during which precipitation is below normal for a particular area2.Agricultural Drought: a period of deficient moisture in the soil layers from which crops and other plants normally draw their water3.Hydrological Drought
