Document Summary
Specific heat: 1 calorie- amount of heat required to raise the temperature of 1 gram of pure water by 1 c unit for specific heat: calories/grams/ c. Salinity: total mass of dissolved inorganic solids (in grams) in 1 kg of seawater (parts per thousand) Salinity of typical of seawater is close to 35 grams of total salts in 1 kg of seawater. Corilolis force: pulls an object to the right in the northern hemisphere, and to the left in the southern hemisphere. Pressure gradient force: wind blows from high pressure toward low pressure. It rises and causes low pressure at the earth"s surface. Ascending air cools as it expands, water vapor condenses into tiny droplets clouds; then possible rains: when air is cooled: Its temp drops as heat is taken away. It sinks and causes high pressure at the earth"s surface. Descending air warms as it compresses, and the droplets (clouds) evaporate, fair weather.
