TEMPERATURE CONTROLS 1. LATITUDE(closer to the equator the warmer the daily temps) Station A 65F 60N Ocean 30N Station B 71F EQ 3. OCEAN CURRENTS(places by warm current are warmer than places by a cold current) 2. LAND vs WATER(coastal places cooler summers warmer winters) Summer/Winter Temps 4. ELEVATION(higher up the cooler it gets) Station A 75F/60F Station B 60F(5000FT) Ocean Station B 95F/45F Station A 72F(500Ft)
