Climate
Climate the overall view of a region’s weather conditions over a long period of time.
Major Aspects of Climate 1. temperature 2. moisture (water conditions)
Temperature Calculations 1. Temperature Range 2. Average Yearly Temperature
Temperature Range: New York 1 2 3 4 5 6 7 8 9 10 11 12 36 40 48 58 68 77 83 81 74 63 52 42 What is the yearly Temperature Range of New York? 83o – 36o = 47oF
Temperature Average: New York 1 2 3 4 5 6 7 8 9 10 11 12 36 40 48 58 68 77 83 81 74 63 52 42 What is the yearly average temperature of New York? 36 + 40 + 48 + 58 + 68 + 77 + 83 + 81+ 74 + 63 + 52 + 42 = 60.1oF
Potential Evapotranspiration (Ep) The amount of water vapor that would evaporate from an area if water were available Largely determined by an area’s amount of energy available (temperature)
Climate Ratio Climates can be classified into four types: 1. arid 2. semiarid 3. sub-humid 4. humid We categorize these types by finding the climate ratio of the region. Climate Ratio= P/Ep (P= precipitation)
Factors that Affect Climate 1. latitude 2. planetary wind and pressure belts 3. oceans and other large bodies of water 4. ocean currents 5. mountains 6. elevation 7. amount of cloud cover 8. vegetation
