The correct answer is option 1: 27°-30°. The jet streams are high-altitude, fast-moving air currents that flow in the upper levels of the atmosphere. In India, the jet streams are located around the subtropical latitudes, specifically between 27°-30° north latitude. These jet streams are called subtropical westerly jet streams because they blow from west to east. They play an important role in determining the weather patterns in the region, affecting the movement of cyclonic systems, monsoon patterns, and air travel routes. By understanding the location of the jet streams, meteorologists can make more accurate predictions about weather systems and their impacts on various regions. It is important to note that the other options (2, 3, and 4) do not correspond to the correct latitude range for the location of the jet streams in India.
