The sun crosses the equator in march and september so those are the wet seasons. Tropical cyclone introduction: warm core, low pressure, no front, organized circulation system that develops in the tropics. A trough is defined as a region of relative low pressure. The majority of tropical cyclones form from easterly waves: west african disturbance line (wadl): this is a line of convection (similar to a squall line) which forms over west africa and moves into the.
