2)   Consider the following statements

1. Depending on severity, a Strom can be called either Hurricanes, cyclones or typhoons
2. High humidity in the lower to middle levels of the troposphere causes typhoons.

Which of the above statements is/are correct?


a. Only 1
b. Only 2
c. Both
d. None
Answer  Explanation 

ANSWER: Only 2

Explanation:
Hurricanes, cyclones, and typhoons are all the same weather phenomenon; we just use different names for these storms in different places. In the Atlantic and Northeast Pacific, the term “hurricane” is used. The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean. The ingredients for these storms include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds. If the right conditions persist long enough, they can combine to produce the violent winds, incredible waves, torrential rains, and floods we associate with this phenomenon.


3)   Which of the following factors are responsible for Typhoon Formation and Development?

1. Warm sea surface temperatures
2. Cold sea surface temperature
3. High humidity in the lower to middle levels of the troposphere
4. Enough Coriolis force to develop a low pressure center
5. A pre-existing low level focus or disturbance
6. Low vertical wind shear
7. Strong horizontal wind shear


a. 1,3,4,5,6
b. 2,3,4,5,6
c. 1,3,4,5,7
d. All
Answer  Explanation 

ANSWER: 1,3,4,5,6

Explanation:
There are six main requirements for typhoon formation and development and they are:
1. Sufficiently warm sea surface temperatures
2. Atmospheric instability
3. High humidity in the lower to middle levels of the troposphere
4. Enough Coriolis force to develop a low pressure center
5. A pre-existing low level focus or disturbance
6. Low vertical wind shear
