Describe the conditions that lead to a tropical revolving storm

Tropical storms can only form between approximately 5° and 30° latitude, as the revolving aspect utilises the Earth's Coriolis effect in order to enable it to spin. Furthermore, the must form above bodies of water that are at least 2km deep. The air above the warm ocean is heated due to latent from evaporation. Once the ocean water reaches at least 27°C, the warm air rises quickly, causing an area of very low pressure. As the air continues to rise quickly it draws more warm moist air up from above the ocean leading to strong winds. The rapidly rising warm air spirals upwards, cools, condenses and large cumulonimbus clouds form.These clouds form the eye wall of the storm and produce heavy rainfall. n the centre of the storm, cold air sinks forming the eye of the storm - here, conditions are calm and dry. As the storm gets bigger, it begins to spin due to the Coriolis force - clockwise in the northern hemisphere and anti-clockwise in the southern. This enables the storm to draw more water in and subsequently fuel the storm. Once the storm reaches land, it slows down and decreases in size due to it not having a source of water for energy.
