The dry, northeasterly , and their more extreme form, the , are interrupted by the northern shift in the and resultant southerly, rain-bearing winds during the summer.

Arroyos and canyons are prone to flooding as runoff from higher areas rush to carry excess rainfall through to lower areas.
The moisture-laden winds on reaching the southernmost point of the , due to its topography, become divided into two parts: the Arabian Sea Branch and the Bay of Bengal Branch. These monsoon winds bind the whole country by providing water to set the agricultural activities. They blow from land to sea and hence for most part of the country it is a dry season. Similar is caused when moist ocean air is lifted upwards by mountains, surface heating, convergence at the surface, divergence aloft, or from storm-produced outflows at the surface. So, a shift in the development of monsoon trough or low pressure trough along with the change of season is the main reason for the reversal of wind direction in Indian subcontinent.
The monsoon also plays a significant role in celebrating festivals, folk dances, music, and other aspects of the cultural life of the people and their dress. As such, obviously the flora, fauna and the entire ecosystem of these areas are heavily dependent on the Monsoon. B India has a monsoon type of climate. This enables even northern India to have uniformly high temperature for their latitudes. But these winds reach the Eastern Ghats last of all so there is less rainfall in Tamil Nadu and consequently it is much lower as compared to the rainfall on the Malabar Coast of the Western Ghats.

Why does rainfall decrease from the east to the west in northern India? Examples are the formation of a rare low-latitude tropical storm in 2001, , and the in 2007.
In respect of both these elements, land and sea contrast in the plateau region plays a significant role. So, Shillong is rainier in June while Kolkata is rainier in July. We study in our Social Studies book of class ninth that monsoon is a unifying bond. Answer : Jodhpur is in the extreme western part of India and so, when the monsoon winds reach it, they have exhausted their moisture. These monsoons winds bind the whole country by providing water to set agricultural activities in motion. The Himalayas thus act as a kind of shield for us and thus this phenomenon results in uniformly high temperatures in India as compared to the other areas in the same latitude. The eastern areas of the Western Ghats do not receive much rain from this monsoon as the wind does not cross the Western Ghats.
