Jet streams are a narrow belt of high altitude (above 12,000 m) westerly winds in the troposphere. Their speed varies from about 110 km/h in summer to about 184 km/h in winter. A number of separate jet streams have been identified. The most constant are the mid-latitude and the subtropical jet stream.

Over India, these jet streams blow south of the Himalayas, all through the year except in summer. The western cyclonic disturbances experienced in the north and northwestern parts of the country are brought in by this westerly flow. In summer, the subtropical westerly jet stream moves north of the Himalayas with the apparent movement of the sun. An easterly jet stream, called the tropical easterly jet stream blows over peninsular India, approximately over 14°N during the summer months.

Jet Stream is the correct answer.
Jet streams are narrow belts of high-speed winds that flow in the upper levels of the atmosphere, specifically in the troposphere. They are characterized by fast-moving, meandering air currents that can reach speeds of up to 184 km/h in winter and around 110 km/h in summer.
Jet streams are primarily driven by the temperature and pressure differences between the polar regions and the equator. These variations in temperature and pressure create strong pressure gradients, which in turn generate the powerful winds associated with jet streams.
Jet streams are found at high altitudes, typically above 12,000 meters (or 39,000 feet). They are concentrated in specific regions of the globe, including the northern and southern hemispheres. In the northern hemisphere, the main jet stream is known as the polar jet stream and is located at around 30,000 feet. In the southern hemisphere, the main jet stream is called the subtropical jet stream and is typically found at approximately 40,000 feet.
Jet streams play a significant role in weather patterns and the movement of air masses around the Earth. They can impact the formation and intensity of weather systems, such as storms and fronts, and can influence the track and speed of aircraft flying within them.
Overall, jet streams are important features of the Earth's atmospheric circulation and have a significant impact on weather and climate. They are instrumental in shaping global weather patterns and are of particular interest to meteorologists and aviation professionals.
