Document Summary
Climate - long-term weather in an area and is determined by temp and precipitation. Introduction to the basic drivers of climate article notes: desert climate = warm +dry. Most important factor that determines what life is found in a specific region. Climate changes include seasonal cycles, el nino events (changes over several years: long-term climate change occurs due to intensity and distribution of sun"s radiation on earth"s surface. Sunlight intensity affecting winds, precipitation, & ocean circulation: Water and air at equator receives more sun = more heat = molecules are spread out (as to cold conditions) ;; difference in density causes heat to rise. Warm air in tropics = wet (sunlight evaporates water from plants, soils and bodies of water: cuz air is warm and less dense, there is enuff room for water molecules in the air mass. But as air passes over cool areas air and water gets more dense water falls as precipitation.
