Which state is the first to see retreating monsoon?
The Arabian Sea Branch of the Southwest Monsoon first hits the Western Ghats of the coastal state of Kerala, India, thus making this area the first state in India to receive rain from the Southwest Monsoon.
Why do South West monsoon winds retreat?
Gradually, the low-pressure trough is replaced by a high-pressure trough, marking the retreat of the monsoon winds. Such changes in the atmospheric pressure patterns cause the monsoons of the Southwest to withdraw. – Hence this time is known as the Southwest monsoon retreat season.
What are southern monsoon winds?
This is the southwest monsoon. This causes the winds to blow over the Indian subcontinent toward the Indian Ocean in a northeasterly direction, causing the northeast monsoon. Because the southwest monsoon flows from sea to land, it carries more moisture, and therefore causes more rain, than the northeast monsoon.
What is the other name of retreating monsoon?
Retreating monsoon is also known as Northeast Monsoon.
What are the four main characteristics of retreating monsoon?
The following are the four main characteristics of the retreating monsoon:
- During October and November, the south-west monsoon winds become weaker and start retreating.
- The retreat of the monsoon is marked by clear skies and an increase in mercury level in the northern plains.
What is the direction of retreating monsoon?
What is a Retreating Monsoon? During the months of October-November, the south-west monsoon winds become weaker and start to retreat from the skies of North India. This phase of the monsoon is known as the retreating monsoon.
What is withdrawal of southwest monsoon called?
The one word withdrawal of Southwest monsoon is retreat. It begins to withdraw during early September from the northwestern states. Thus, the withdrawal of the southwest monsoon is called retreat or retreating monsoon.
How monsoon winds are formed?
The air over the land gets heated and rises. This causes the winds to flow from the oceans towards the land, which gives rise to Monsoon winds. The pressure difference in adjoining areas gives rise to air movement which leads to the formation of Monsoon winds.
What type of wind is monsoon?
A monsoon is a seasonal wind system that shifts its direction from summer to winter as the temperature differential changes between land and sea. Monsoons often bring torrential summerrains, such as on the Indian subcontinent where the summer monsoon delivers three-quarters of the country’s annual precipitation.
What causes retreating monsoon?
Temperature & Pressure – Retreating monsoon As the monsoon starts retreating towards the south, the pressure gradient becomes low. Local pressure conditions usually affect the wind flow during that time.
What are the three features of retreating monsoon?
This stage is the transition time from the hot rainy season to the cold winter season. It is characterized by a clear sky, moist soil, and high temperatures that give birth to the heat of October. A trough of low pressure moves to the Bay of Bengal.
What are the retreating monsoons?
Where does the retreating monsoon in India pick up moisture?
An exception to that rule occurs along the southeastern coast of India and for some distance inland. When the retreating monsoon blows from the northeast across the Bay of Bengal, it picks up a significant amount of moisture, which is subsequently released after moving back onto the peninsula.
What happens to the sky when the monsoons retreat?
With retreat of the monsoons, the clouds disappear and the sky becomes clear. The day temperature starts falling steeply. The diurnal range of temperature increases due to lack of cloud cover. As the monsoons retreat, the monsoon trough weakens and gradually shifts southward.
When do South West monsoons withdraw from Coromandel?
The south-west monsoons reach Coromandel coast in the first week of June and withdraw from there only in the middle of December. Unlike the sudden burst of the advancing monsoons, the withdrawal is rather gradual and takes about three months. With retreat of the monsoons, the clouds disappear and the sky becomes clear.
How long does it take for withdrawal of monsoons?
Unlike the sudden burst of the advancing monsoons, the withdrawal is rather gradual and takes about three months. With retreat of the monsoons, the clouds disappear and the sky becomes clear. The day temperature starts falling steeply. The diurnal range of temperature increases due to lack of cloud cover.
