The correct answer is option 1, which states that statement 1 is correct while statement 2 is incorrect. Let`s analyze each statement separately:

Statement 1: Sudden storms and strong winds are the characteristics of equatorial low pressure area.

This statement is correct. The equatorial low pressure area, also known as the Intertropical Convergence Zone (ITCZ), is characterized by unstable conditions and intense convective activity. It is associated with thunderstorms, heavy rainfall, and strong winds.

Statement 2: Westerly jet streams are seen in the northern hemisphere only.

This statement is incorrect. Jet streams are high-altitude, narrow air currents that move from west to east. While the westerly jet stream is most commonly found in the mid-latitudes of the northern hemisphere, it can also occur in the southern hemisphere. In fact, both hemispheres have jet streams, although their patterns may vary.

To summarize, statement 1 is true as sudden storms and strong winds are indeed characteristics of the equatorial low pressure area. However, statement 2 is false as westerly jet streams can be found in both the northern and southern hemispheres.
