Fig. 13-6, p. 361 The Global Pattern of Climate Major features of Earth's climate distribution (moist tropical, dry, moist/mild winter, moist/severe winter, polar, highland) local variations within larger climate regions Tropical Moist Climates tropical wet (Af) tropical monsoon (Am) Tropical Moist Climates tropical wet and dry (Aw) Savanna Dry Climates arid (BW) Dry Climates semiarid (BS) Moist Subtropical MidLatitude Climates humid subtropical (CfA) (west coast) marine (CfB) Moist Subtropical MidLatitude Climates Mediterranean (Cs) coastal Cs interior Cs Moist Climates with Severe Winter
