Climatology-study of climate change Climatic regions: similar weather statistics Meteorology- Climatic region-constantly changing, but have similar -genetic classification -empirical classification Biomes-major categories of types of regions found on earth, include forests, ---grassland, tundra, desert ****subject to change -when weather changes, so does vegetation, what El Nino-present patterns shift from usual location -trade winds are weakened and sometimes even switched General circulation patterns in ocean of currents, El Nino is the subsiding of those currents -SST increase, S.Pacific-usually cold upwelling (currents going up providing nutrients) decreases---IMPACTS ENTIRE GLOBE ‘enso’-El Nino Southern Oscillation La Nina -SSTs become colder -Droughts hurricanes flooding What effects climate change *Insolation (amt of sunlight-daylength), temp(latitude), pressure, air mass, precipitation aerosols—volcanic eruptions, ash blocks sunlight, reduces temp aerosols from humans-carbon burning, sprays etc. . human causes decomposing genetic classification-causation matters (for ex: the interaction of air masses) imperical classification-observed effects-climate according to vegetation midlatitude-seasonal microthermal- climograph-shows montly temp and precipitation for a station -measure these climate regions *characteristics and location •Tropical –rain forest (rainy all year) -monsoon(6-12 months rainy) -savanna(<6 months rainy) Tropical Rainforest -mT -high biodiversity, rain, temps, along equator Tropical Monsoon Climates

-along coastlines of tropical rainforest Tropical Savanna -poleward (N or S) -edge of tropical rainforest -summers wetter than winters -high pressure •Mesothermal(midlats, mild winters) -humid subtropical (hot summers) -marine west coast(warm to cool summers) Humid subtropical •Microthermal •Polar •Highland •Dry Tropical Rain Forest Lush evergreen, convectional thunderstorms, moist and warm conditions, bacterial action on the ground (don’t walk barefoot) lots of things not exposed to sunlight, soil sterile and don’t contain nutrients, tree has most nutrients -high in biodiversity-organisms, species, plant life very high abundance -located close to equator-ITCZ (S.America, Africa, Indies) Tropical Monsoon Climate
