Tropical Storms Flashcards
Tropical storms over warm oceans (Above __°)
Tropical storms over warm oceans (Above 27°)
How do tropical storms form? (1/7)
Strong upward movement draws water vapour from surface of warm ocean.
How do tropical storms form? (2/7)
This evaporated air cools as it rises, and then condenses to thunderstorm clouds.
How do tropical storms form? (3/7)
As the air condenses it releases heat which powers the storm and draws more water up from the ocean’s surface.
How do tropical storms form? (4/7)
Several smaller thunderstorms join together to form a giant spinning storm, winds reaching up to 120kmph (75mph) means it becomes officially a tropical storm.
How do tropical storms form? (5/7)
Storm develops an eye at it’s centre where air descends rapidly, Outer edge of the eye is the eyewall where the most intense weather conditions (strong winds and heavy rain) are felt.
How do tropical storms form? (6/7)
As the storm is carried across the ocean by the winds, it continues to gather strength.
How do tropical storms form? (7/7)
On reaching land the storm’s energy supply (evaporated water) is cut off.
Friction with the land slows it down and begins to weaken, if the storm reaches warm seas after crossing it may become stronger again, however if not it will dissipate and settle.
