Document Summary
Climate is the average weather of a region. Temperature and precipitation are two of the key measures of climate. There are three primary factors that control the magnitude/range of temperatures experienced: latitude, longitude, and elevation o o. In coastal locations, temperatures are more moderate and seasonal variations are minimal, with the least seasonal variation at the equator and the greatest towards the poles o. In continental locations, temperatures are more extreme and seasonal variations are more pronounced, with the least seasonal variation at the equator and the greatest towards the poles. These patterns are in large determined by air mass characteristics and movements, which in turn are affected by latitude, topography, air masses, persistent pressure patterns, and atmospheric and oceanic circulation: dry and moist climates. Classified according to the amount of precipitation they received compared with the total evaporation. Dry the total evaporation of moisture from the soil and from plant foliage greatly exceeds the annual precipitation.
