EQ2 - 1.4 Tropical Cyclones Are Caused By Particular Meteorogical Conditions Flashcards
What is the Coriolis Force?
A strong force created by the earths rotation.
What is the eye of a tropical cyclone?
The centre of a tropical cyclone.
What is meant by seasonal distribution?
How something such as tropical cyclones occur at different times of the year.
What is the source area?
The region in which a tropical storm first forms.
What is meant by track?
The path followed by a tropical storm.
At what temperature does a tropical cyclone develop?
When sea temperatures exceed 26.5 degrees Celsius.
What are the features of the eye in a tropical cyclone?
There is clear sky and no winds.
How does wind rotate at the top of a tropical cyclone?
Winds rotate outwards at the top of a tropical cyclone.
How does air move throughout the cyclone?
Warm moist air rises and pulls towards the centre.
When do tropical cyclones develop in the Northern hemisphere?
Develop in late summer.
How high can cloud tops reach in a tropical cyclone?
They can reach 12-15KM.
What clouds form at the top of a tropical cyclone?
A dense canopy of cirrus clouds form at the top.
What are the characteristics of winds in the eye wall?
The winds in the eye wall is where the winds are strongest.
What clouds form in a tropical cyclone?
Cumulonimbus clouds form.
How do storms fully converge into a tropical cyclone?
- Moist, warm air that us warmer than 26.5 degrees Celsius.
- The time of year where the ocean water is likely to be at its warmest.
- Winds converging at the ocean surface, causing the air to rise.
- Formation away from the equator so the Coriolis effect will cause the storm to rotate.
