how tropical storms form

Flussdiagrammknoten

• A strong upward movement of air draws water vapour up from the surface of a warm ocean

• this evaporated air cools as it rises and condenses to form a towering thunderstorm clouds

• As the air condenses it releases heat which powers the storm and draws up more and more water from the ocean

• several smaller thunderstorms join together to form s giant spinning storm. when the surface winds reach an average of 120km per hour(75 miles per hour) it is officially a tropical storm

• the storm now develops an eye at its centre where air descends rapidly. The outer edge of the eye is the eyeball share the most intense weather conditions are.

• as the storm is carried across the ocean by prevailing winds it gathers strength

• on reaching land the storms energy supply(the water)is cut off.friction with land also slows and weakens it .
