Document Summary

27 oc warm oceans in the equatorial zone. 24 oc warm oceans in the tropical zone. Least: an air mass usually has a well-defined boundary, called a front, between itself and a neighboring air mass. A warm front moves into a cold area, and rises above it. It is gradual, and has long but light rainfall. A cold front moves into a warm area; it is steeper and denser, and has short but heavy rainfall. An occluded front is produced when a fast cold front overtakes a slow warm front: at mid-latitudes, travelling cyclones & anticyclones change weather conditions as they pass across regions. Mid-latitude (wave) cyclones affect arctic/antarctic zones, and range in strength (weak-vigorous). Tropical cyclones affect tropical/subtropical zones, and can cause hurricanes and typhoons. Tornados are relatively-strong cyclones associated with intense and enormously powerful winds. Chapter 8 : the global scope of climate: climate is the average weather of a region.
