2. What environmental conditions are required for the formation of tropical cyclones?

3. Why do we see the largest storm surge on the right side of the eye of the hurricane, looking towards the direction that the storm is moving in?

4. How may upwelling in the ocean impact a hurricane’s energy source, especially if the warm ocean layer is shallow?

5. How might climate change affect the (1) frequency, (2) intensity, and (3) duration of hurricanes? Explain.

6. What is the difference between a typhoon and a hurricane? Are these fundamentally different storm systems? Explain.

Explanation / Answer

1. Air generally moves in the direction of the Equator.moving air is deflected by the rotation of the Earth.In northern hemisphere the deflection is towards the right and southern hemisphere it is towards the left.air moving towards the equator from the south is towards left . Hence so.

2. Warm water atleast of 80 degree Fahrenheit atleast on the order of 50m is required.An atmosphere which cools fast enough with height so that it is potentially unstable to moist convection. A minimum distance of atleast 500km from the equator . Relatively moist layers near the mid troposphere.
