Heat Capacity Heat capacity = heat absorbed/temperature change Ocean Water = 1 Continent Soil = 0. 2
Heat Capacity Heat capacity = heat absorbed/temperature change Heat Capacity of Water = 1 (1 calorie of heat is needed to raise the temperature of 1 gram of water by 1°C) Ocean Continent Oceans warm up and cool off slower than adjacent continents.

Quick Summary—Monsoons and Ocean Currents: • Monsoonal climates have major seasonal shifts in the prevailing wind direction • These wind shifts are driven by seasonal heating and cooling of land resulting pressure pattern changes • warm season = wet monsoon (low pressure) • cool season = dry monsoon (high pressure) • Surface ocean currents move about 45 degrees from prevailing surface wind direction • Currents circulate in closed loops (“gyres”) • Ocean currents moving poleward are warm currents • Ocean currents moving equatorward are cold currents
