Document Summary
Climate refers to average weather conditions over long periods of time. Concerned with both their average value for each month and variation across the months. Natural vegetation is strongly influenced by temperature and precipation. Latitude near the equator, temperatures are warmer and annual range is low toward the poles, temperatures are colder and annual range is greater. Produced by the latitudinal variation in the annual cycle of insolation. Coastal regions show a smaller annual range in temperature while continental interiors display larger range. Warm air can hold more moisture than cold air. Colder regions generally have less precipitation than warmer regions. Precipitation will tend to be greater during warmer months. Distinctive types of annual temperature cycles related to latitude and location image of different global temperature regimes - slide 7. **draw in relation to circulation and air masses. Most influenced by pressure systems and the global circulation. Subtropical highs pressure cells, characterized by dry, subsiding air.
