Why don't tropical cyclones develop on the equator?

Best Answers

The formation of a tropical cyclone requires a number of favourable environmental conditions and one of them is a suitable latitude. Almost all tropical cyclones form over regions more than 5 degrees of latitude away from the Equator and very few occur near the Equator. read more

Tropical cyclones do not form near the Equator (within 5 degrees latitude) b/c the Coriolis force is 0 and air tends to flow straight into low pressure centers, so it feels up before the pressure can drop enough. read more

The rotation of a large-scale weather system depends on theCoriolis effect, in which moving air is deflected relative toearth's surface. read more

Thunderstorms begins to develop, which further fuel the cyclone. To sustain the spiraling movement of the strengthening hurricane, the force of the Coriolis Effect must be sufficient, which becomes non-existent at the equator. Any developing weather disturbances along the equator do not gain enough traction to become a hurricane. read more
