Document Summary
An isotherm connecting all points of highest average temperature. North american isotherms bend toward the equator. Persian gulf has the highest recorded sst (96*f) Generally speaking, the southern hemisphere"s patterns are influenced by more marine, where the northern hemisphere is influenced more by continentality. Therefore, the nh experiences more extremes than does the sh. Molecules of air create a pressure by moving around. Evangelista torricelli was the first guy to develop a barometer. Winds are named for the direction from which they originate. Ex) a wind from the west is a westerly wind. (it is blowing eastward) National weather service standardized the scale in 1995. More of a memorable thing than actually used for measurements. The four forces determine both speed and direction of wind. High and low pressure areas exist in the atmosphere principally because earths surface is unequally heated. Poles cold, dense air exerts greater pressure. Equator warm, less dense air exerts less pressure.
