Document Summary

Low pressure system without any front attached. Warm ocean waters (80 f/27 c) throughout a depth of about 150 ft. An atmosphere which cools fast enough with high that is its potential unstable to moist convection. Relatively moist air near the mid-level of the troposphere (16,000 ft. ) Generally a minimum of 300 miles from the equate. Low values (less than 23 mph/37 km/h) of vertical wind shear between the surface and upper troposphere. Needs warm waters, so natural that they form near the equator. Storms usually do not form within 5 latitude of the equate due to lack of coriolis force. Easterly waves: an inverted trough of low pressure moving generally westward in the tropical easterlies. West african disturbance line (wadl: this is a line of convection which forms over west african and moves into the atlantic ocean. Tutt: a tropical upper tropospheric trough is a trough or cold core low in the upper atmosphere, which produces convection.
