Where does orographic rainfall occurs in India?

The Western Ghats
Complete answer: The Western Ghats in India provide favorable conditions for orographic rainfall. The warm and moist air from the Arabian sea is blocked by the Western Ghats and gets lifted over mountain ranges.

What is the distribution of rainfall in India?

(i) The western coast and northeastern India receive rainfall of over about 400 cm. (ii) It is less than 60 cm in western Rajasthan and adjoining parts of Gujarat, Haryana and Punjab. (iii) Rainfall is equally low in the interiors of the Deccan plateau and east of the Sahyadris.

What is the area of orographic rainfall?

orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.

Where is orographic rainfall most common?

Orographic precipitation is well known on oceanic islands, such as the Hawaiian Islands or New Zealand, where much of the rainfall received on an island is on the windward side, and the leeward side tends to be quite dry, almost desert-like, by comparison.

Which part of South India receives orographic rainfall?

Western Ghats and West Coastal plains.

Where does the orographic effect occur?

The orographic effect occurs when air masses are forced to flow over high topography. As air rises over mountains, it cools and water vapor condenses. As a result, it is common for rain to be concentrated on the windward side of mountains, and for rainfall to increase with elevation in the direction of storm tracks.

What is the distribution of rainfall?

Factors controlling the distribution of rainfall over the earth’s surface are the belts of converging-ascending air flow (see doldrums; polar front), air temperature, moisture-bearing winds, ocean currents, distance inland from the coast, and mountain ranges.

What is mean by distribution of rainfall?

Global distribution of mean annual rainfall (in centimetres). Because rainfall results from the ascent and cooling of moist air, the areas of heavy rain indicate regions of rising air, whereas the deserts occur in regions in which the air is warmed and dried during descent.

Which locations are impacted by the orographic effect?

The extensive dry regions of Asia (Turkestan east to the Gobi Desert of China) and the Great Basin Desert of North America are the result of orographic effects on the flow of air masses (Manabe and Broccoli, 1990).

What is orographic rainfall class 9 geography?

Orographic rainfall is also known as relief rainfall occurs when moist air is forced to rise over a mountain range.

Which of the following receives orographic rainfall?

Explanation: In Brazil, Northeast areas receives orographic type of rainfall. Orographic rainfall occurs when the rain bearing winds strike against the mountains and this immediately results in precipitation on the windward side of those mountains.

What is orographic rainfall class ninth?

Orographic rainfall is precipitation produced when the mountains of uplands act as barriers to airflow, forcing the air to rise and the moist air moving upslope coo down by producing clouds and precipitation. The clouds and precipitation will be concentrated on the windward side of the mountains.
