Warm moist air to convect and therefore the pressure falls. The rising air cools and condenses forming clouds.

Warms the air and it rises further, cools, condenses and releases further latent heat forming continuous upwards convection currents. Thick, cumulonimbus clouds grow rapidly and give heavy rainfall and thunderstorms.

Into the low-pressure system from different directions causing high speed winds at the earth's surface.

hurricanes follow a spiral path due to the Coriolis Effect.
