Consider the following statements:1. Jet streams occur in the Northern...
Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.
Since these hot and cold air boundaries are most pronounced in winter, jet streams are the strongest for both the northern and southern hemisphere winters. Hence, statement 1 is not correct.
The “eye” of Tropical Cyclone is a roughly circular area of comparatively light winds and fair weather found at the center of a severe tropical cyclone.
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 (Hawkins and Rubsam 1968). 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).
Therefore, the correct answer is (c).

1. False. Jet streams occur in both the Northern and Southern Hemispheres.
2. True. Not all cyclones develop an eye, which is a calm region at the center of the cyclone with low pressure and clear skies.
3. False. The temperature inside the eye of a cyclone is not fixed, but it is generally warmer than the rest of the cyclone due to sinking air and compression. The exact temperature can vary depending on various factors such as the strength and size of the cyclone.
