GEOL 101 Lecture Notes - Lecture 7: Semi-Arid Climate, Rain Shadow, Vehicle Emissions Control
Document Summary
Temperature regimes- comparing maritime climates (less variability in seasons) v. continental climates (away from coast: koppen classification, a climates (tropical humid) (intertropical convergence zones, within 20 degrees of the equator. Average monthly temperature of >18 deg c (64 deg f: brazil, africa, latin america. Af: tropical wet climate (every month> 6cm rain, highest average annual precipitation) (warm and rainy all year) Am climates: monsoon climate, rainfall peaks in summer (one or more months < 6cm rain) (asia, australia, southern asia) Aw: savanna climate (drier than other a climates) very seasonal( summer rain, dry winter, grassland vegetation: b climates (dry) (based on rainfall pattern) (hottest) About 30% of the earth s lands area is a dry continental zone. Three main causes for deserts are: subtropical highs, rainshadow, west coast deserts/ cold currents. Coldest month less than 0 deg c (no d climates in the southern hemisphere but receive 4 seasons)
