What causes the orographic effect?

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 causes orographic rainfall in India?

Orographic rainfall occurs when rain bearing winds strike against the mountains and result in precipitation on the windward side of the mountains. In India, rainfall is orographic in nature as heavy rains occurs on the windward slopes of the Western Ghats and scanty rainfall on the leeward side.

How are orographic rainfall caused Class 7?

Orographic rainfall occurs when a mass of air is pushed up because of a structure with very high elevation, such as a mountain. The lifted air cools down and precipitation occurs. Rain shadow area is formed on the other side of the elevation.

What is orographic rain?

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.

Where does orographic rainfall occur in India?

The Western Ghats
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.

Where does orographic rainfall occur in the world?

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.

Why do the Western Ghats cause orographic rain?

As the summer (wet) monsoons approach the West Coast of India, they rise up the western Ghats (mountains) and the air cools. This cool air is less able to hold moisture and it is released as rainfall. This is called OROGRAPHIC RAINFALL.

Why orographic types of rainfall is more prominent in India?

The Indian rains are chiefly orographic in nature. As a result, the regions situated on the windward side receive greater rainfall than the regions located on the leeward side. Only a scant amount of rainfall is received from cyclones and convectional rainfall.

What is orographic rainfall Wikipedia?

Orographic precipitation, also known as relief precipitation, is precipitation generated by a forced upward movement of air upon encountering a physiographic upland (see anabatic wind). The upward deflection of large scale horizontal flow by the orography.

In which region of Maharashtra orographic rainfall occurs?

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.

Which type of rainfall is caused by the Western Ghats?

western ghats receive monsoon type of rainfall.
