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 10°C lesser than that of the
surroundings.
Which of the statements given above is/are correct?
Jet streams are the strongest for both the northern and southern hemisphere winters. Hence, statement 1 is not correct. The eye is the region of lowest surface pressure and warmest temperatures aloft (in the upper levels) – the eye temperature may be 10°C warmer or more at an altitude of 12 km than the surrounding environment, but only 0-2°C warmer at the surface in the tropical cyclone. Hence, statement 3 is not correct. The formation of an eye is almost always an indicator of increasing tropical cyclone organisation and strength. Because of this, forecasters watch developing storms closely for signs of eye formation. But in Extratropical Cyclones or Temperate Cyclones, there is not a single place where winds and rains are inactive (as in case of Tropical Cyclone). Hence, statement 2 is correct. Therefore, the correct answer is (c).
