Answers
Answer:
Low pressure over land - Cyclonic depressions
Air currents - Summer
Seasonal reversal - Monsoon winds
Winter rainfall in Tamil Nadu - North-east Monsoon
Winter rainfall in Delhi - Jet Streams
Explanation:
Low pressure over land - Cyclonic depressions
Areas of high pressure are called anticyclones, and low pressure areas are known as cyclones or depressions. Anticyclones typically result in stable, fine weather, with clear skies whilst depressions are associated with cloudier, wetter, windier conditions.
Air currents - Summer
Air currents are caused by the sun's uneven heating of the Earth. As the Earth's surface is heated, it warms the air just above it. The warmed air expands and becomes lighter than the surrounding air. It rises, creating a warm air current.
Seasonal reversal - Monsoon winds
A monsoon is a seasonal reversal in wind patterns over a region.
Winter rainfall in Tamil Nadu - North-east Monsoon
North-east trade winds is the main reason behind winter rainfall in Tamil Nadu. As the state is situated in the eastern coast of India, the southern portion of India receives rainfall from the Southwest monsoons which are obstructed by the Western Ghats.
Winter rainfall in Delhi - Jet Streams
Delhi gets winter rainfall due to Western distubances. Western disturbances, specifically the ones in winter, bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent. During the winters, the low pressure belt of temperate zone slides down over the Northern India. Due to which the feeble temperate cyclones originating over Mediterranean Sea move along western jet stream strikes North India.
