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

WEATHER MEASURING INSTRUMENTS 10F 20F 30F THERMOMETER(used to measure outside air temp) Example below shows the temp at 30F WIND VANE(used to measure wind direction) ANOMETER(also on the wind vane used to measure speed located in blue On this diagram) 990mb 1000mb 1010mb 1020mb BAROMETER(used to measure the air pressure outside your station)
