Document Summary

Air always moves from high pressure areas to low pressure areas. Low pressure areas are created at the itcz due to solar radiation causing evapotranspiration. Warming air can hold increasing amounts of water in vapor form and vice versa. Surface winds increase and these bring more moisture and this feeds the storm and causes more growth of the system. More water vapor is condensed and more heat (energy) is released. The air continues to rise a(cid:374)d this triggers (cid:373)ore co(cid:374)de(cid:374)satio(cid:374), etc . Matthew was 75 mph over myrtle beach. So if warm air and moisture are available, the disturbance can get bigger and more developed and turn into a hurricane. The strongest winds are in the eyewall** Note the number of categories used to classify hurricanes according to the saffir- Note the five primary factors that determine the degree of damage of a hurricane. Typical cyclones range in diameter from 100-10000 feet.
