Question

Consider the following statements: 

1. Jet streams occur in the Northern Hemisphere only.

2. Only some cyclones develop an eye.

3. The temperature inside the eye of a cyclone is nearly 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 1

(c) 2 only

Jet streams occur in both the Northern and Southern Hemispheres. 

Hence statement 1 is not correct.

Extra-tropical cyclones may not always have an eye, whereas mostly mature storms have well-developed eyes.

Rapidly intensifying storms may develop an extremely small, clear, and circular eye, sometimes referred to as a pinhole eye. 

Hence statement 2 is correct.

It is warmer and not colder inside the eye of the tropical cyclone.

The warmer temperature is what drives the storm. 

Hence statement 3 is not correct.
