Jet streams are powerful, fast-moving air currents that are found in the Earth’s atmosphere. They are an important part of the global climate and are responsible for influencing weather patterns all over the world, including India. In this article, we will discuss what jet streams are and how they affect the climate in India.
What are Jet Streams?
Jet streams are narrow bands of strong winds that travel around the Earth in the upper atmosphere. These winds can reach speeds of up to 200 mph and can travel up to 3,000 miles in a day. Jet streams are created by the uneven heating of the atmosphere. The difference in temperature between the warm air near the equator and the cold air near the poles creates a pressure gradient, which causes the winds to blow from the poles to the equator.
Jet streams are divided into two main categories: the polar jet stream and the subtropical jet stream. The polar jet stream, also known as the circumpolar jet stream, is located near the Arctic Circle and moves from west to east. The subtropical jet stream, on the other hand, is located near the tropics and moves from east to west.
How Do Jet Streams Affect India’s Climate?
Jet streams have a major influence on India’s climate. The polar jet stream is responsible for bringing cold air from the Arctic Circle to India during the winter months. This cold air causes temperatures to drop and leads to the formation of snow and ice in certain regions. On the other hand, the subtropical jet stream brings warm air from the tropics. This warm air helps to keep temperatures in India relatively warm during the summer months.
Jet streams also influence the monsoon season in India. The monsoon season is caused by the difference in air pressure between the Indian Ocean and the landmass of India. During the summer months, the subtropical jet stream brings warm, moist air from the Indian Ocean to India. This warm air causes the air pressure over India to be higher than the air pressure over the Indian Ocean, resulting in the monsoon rains.
