Question: What are jet streams and how they affect the climate of india?
Jet streams are fast-flowing, narrow, and meandering air currents located in the upper atmosphere, typically at altitudes of around 9-16 km. They are caused by differences in temperature and pressure between the polar and tropical regions and the spinning of the Earth. The jet stream can have a significant impact on the climate of India, particularly during the winter months. The subtropical jet stream, which flows over northern India during the winter, can cause the formation of western disturbances, which are low-pressure systems that bring winter rain and snow to northern India. On the other hand, during the summer, the presence of the tropical easterly jet stream can bring monsoon rains to the region, which is critical for agriculture and water resources. However, changes in the strength or position of the jet stream due to natural variability or human-induced climate change can lead to changes in weather patterns, affecting the timing and amount of rainfall, and consequently, the agriculture and economy of the region.
