Document Summary

For example, atmospheric fronts are important in both: define front . The moist air fuels the storm. (comeback maybe) Severe cyclonic tropical storm in the north atlantic. Using the saffir-simpson hurricane scale; the velocity of wind, the height to which the sea rises and the extent of destruction are used to scale hurricanes. Range from category 1-5: list all the conditions essential for successful development of a hurricane north of the equator and in the atlantic ocean. Begin with a disturbance in the westward-flowing air not far from the equator. The sea surface temperature must be 26 c, this is necessary to produce the latent heat energy needed to power the hurricane. Needs open water to maintain and grow in strength as it receives its power from warm waters. Requires a slowly moving or stationary cold front that produces a bulge in the boundary between cool and warm air moving in opposite directions.
