Climate: Why organisms live where they do  Physical factors drive the distribution of organisms o Light o Temperature o Precipitation  Global climate is driven by o Sunlight (tropics) o Movement of planet o Atmospheric and ocean circulation  Primary driver of climate o The sun  More intense at tropical latitudes  Because of vertical rays  As air rises and cools, it loses moisture = rain o Air moving upward at equator creates inter-tropical Convergence Zone o Dry cold air is dense, picks up moisture o Hadley cells are generated by ITCZ  Prevailing winds that blow east and west are generated by The Coriolis Force o Deflection of air mass is behind direction of spin o Tradewinds develop by moving slower to faster  Forces also affect ocean circulation o Shallow currents driven by prevailing winds o Large scale gyres (movement of water) driven by coriolis forces  Changes in ocean circulation can have huge impact on climate o El Niño southern oscillation  Non el nino  Warm water piles up on Western side (Pacific)  Water comes from below to replace water moved o Nutrient rich  Tradewinds stop, water on Western side moves to eastern side  Shuts down nutrient rich input
