The southern branch blows eastwards south of the Himalayan ranges along 25° N latitude Rajasthan. In India, the monsoon lasts for 100 to 120 days from early June and to mid-September. The overall pattern of the advance follows a , but local episodes may differ considerably. Without them, the southwest monsoon winds would blow right over the Indian subcontinent into , , and without causing any rain. This creates low pressure on the landmass, while high pressure is created over the seas during daytime, but is reversed during the night time.
Forecasts may be further refined in May by comparing rainfall patterns in both Zimbabwe and with the easterly winds above the city of Kolkata in state. When the summer monsoon is late or weak, the regions suffers. Another part strikes the Saurashtra Peninsula and the Kachchh. Its withdrawal from India typically starts at the beginning of September and finishes by the beginning of October. The South west monsoon is also called as a Sea breeze and produces more rainfall than North East monsoon.
As India further cools during September, the southwest monsoon weakens. Most of the are also rain-fed and monsoon-dependent. However, these weather systems are more frequent in the Bay of Bengal. India is positional situated in North — East trade winds and should have N- E winds throughout the year, but a little pressure through lies along the Ganges and upper India, due to which S-W winds predominate.

This South-West monsoon that flows in to India brings about a major change in its weather.
You are sure to see the other side of colourful India during monsoon and also avail the low air fares and costs of stay during this season. To fill this void, the moisture-laden winds from the rush into the subcontinent. Now imagine 60 litres of water filling that! Above the heated land, the air below 1,500 metres 5,000 feet becomes unstable, but it is held down by the overriding easterly flow. One branch is located to the south of the Himalayas, while the second branch is positioned to the north of the Tibetan Plateau. The withdrawal takes place progressively from north to south from the first week of December to the first week of January. South Asian monsoon Onset dates and prevailing wind currents of the southwest summer monsoons in India The southwestern summer monsoons occur from July through September.
It reaches its greatest speed at its normal position to the south of the anticyclonic ridge, at about 15° N from through India. The influence of the Southwest Monsoon is felt as far north as in China's. During the monsoon, the wind direction reverses. It strikes the Indian mainland around 1 June near the Malabar Coast of Kerala. The good news is that visiting India in monsoon is still possible.
It flows every two to five years in place of the cold Peruvian current. Finally, it reaches its end on the Indian coast of Africa. Strictly speaking these winds are planetary winds known as Northeast Trades. Keeping clothes dry becomes difficult which soon starts smelling damp. Unlike the western part of Southeast Asia, the eastern, Pacific coast of Southeast Asia experiences its rainy season in the winter. However, you must note here that during weak monsoon condition when there is ample sunshine, the lower levels of the atmosphere are warm which gives rise to convection current. The southwest monsoon is generally expected to begin around the beginning of June and fade away by the end of September.
Monsoon onset and early developments As the high-sun season that is, the Northern Hemisphere summer moves northward during April, India becomes particularly prone to rapid heating because the highlands to the north protect it from any incursions of cold air. However, many meteorologists argue that the monsoon is not a local phenomenon as explained by the traditional theory, but a general weather phenomenon along the entire of. The dynamic theory explains the monsoon as a global weather phenomenon rather than just a local one. The reverse happens during the winter, when the land is colder than the sea, establishing a pressure gradient from land to sea. It usually arrives in approximately 10 days later, reaches by the end of June, and covers the rest of India by mid-July. By the end of May, the monsoon trough further intensifies over north India due to high temperature. This is the southwest monsoon.
Precipitation then occurs on the windward side of the highlands because of and condensation of the moist rising air. It has an annual period of occurrence. If it rains the same amount this year, then we will say that India had a normal monsoon in 2011. However, over Indian Ocean south of the equator high pressure belt begins to develop in this season. By June end, the monsoon winds are usually established over most parts of India.
