Question
Q59.Consider the following statements:
A. Jet streams Occur in the Northern Hemisphere only.
B. Only some cyclones develop an eye.
C. The temperature inside the eye of a cyclone is nearly 10 C lesser than that of the surroundings.
Which of the statements given above is/are correct?
A. 1 only
B. 2 and 3 only
C. 2 only
D. 1 and 3 only
Answer: C
Detailed Explanation
- Jet streams occur in both the Northern and Southern Hemispheres.
- Jet streams occur in both the Northern and Southern Hemispheres.
- Extra-tropical cyclones may not always have an eye.
- Eye :It is warmer and not colder for a tropical cyclone. The warmer temperature is what drives the storm
- Note : Tropical cyclones are characterized and driven by the release of large amounts of latent heat of condensation as moist air is carried upwards and its water vapor condenses. This heat is distributed vertically, around the center of the storm. Thus, at any given altitude (except close to the surface where water temperature dictates air temperature) the environment inside the cyclone is warmer than its outer surroundings.
- Eye :It is warmer and not colder for a tropical cyclone.
The warmer temperature is what drives the storm.
