Which of the following affects Indian monsoon ?
El Niño
Tibetan Plateau
Jet Streams
All of the above
None of the above
All of the above
The Indian Monsoon is a complex meteorological phenomenon influenced by various atmospheric and oceanic factors. El Nino disrupts normal circulation, the Tibetan Plateau acts as a high-altitude heat source driving the monsoon engine, and Jet Streams (Subtropical Westerly and Tropical Easterly) dictate the onset and withdrawal of the monsoon.
The Indian Monsoon is a complex meteorological phenomenon influenced by various atmospheric and oceanic factors. El Nino disrupts normal circulation, the Tibetan Plateau acts as a high-altitude heat source driving the monsoon engine, and Jet Streams (Subtropical Westerly and Tropical Easterly) dictate the onset and withdrawal of the monsoon.
The monsoon mechanism is primarily governed by the Inter-Tropical Convergence Zone (ITCZ) and the differential heating of the land and sea, a fundamental concept in Indian Climatology.
El Nino creates warm ocean conditions in the Pacific, which typically leads to deficient rainfall in India.
The Tibetan Plateau absorbs intense solar radiation in summer, creating a low-pressure cell that draws the monsoon winds towards the subcontinent.
The withdrawal of the Subtropical Westerly Jet Stream from the North Indian plains is the primary trigger for the onset of the Southwest Monsoon.
The Tropical Easterly Jet Stream is responsible for the formation and intensity of the monsoon in the Indian peninsula.
El Nino is the warm phase of the ENSO (El Nino-Southern Oscillation) cycle, often resulting in drought-like conditions in India.
Tibetan Plateau heating is crucial for the establishment of the Tropical Easterly Jet, which aids in monsoon rainfall distribution.
All listed factors collectively create the high-pressure and low-pressure gradients necessary for the Indian monsoon cycle.
The Indian Ocean Dipole (IOD) is another critical factor frequently tested alongside these elements in the context of monsoon variability.
D is correct тАФ El Nino, the Tibetan Plateau, and Jet Streams are all vital components that modulate the intensity and timing of the Indian monsoon.
When studying monsoon variability, always correlate El Nino/La Nina impacts with the Indian Ocean Dipole (IOD) as they are the two primary drivers of inter-annual monsoon rainfall fluctuations in India.
