What is the name of the physical features that creates precipitation from the orographic effect in southwest India?
India's Western Ghats, a mountain range on its western coast, for example, causes orographic precipitation on its windward side. The Himalaya Mountains similarly result in orographic precipitation.
Under what conditions does orographic precipitation occur quizlet?
Orographic precipitation occurs when moist air is forced upwards over rising terrain, such as a mountain. Precipitation can also fall in either liquid or solid phases, or transition between them. Liquid forms of precipitation include rain and drizzle.
What physiographic feature creates orographic rainfall?
Desert mountains influence rainfall by orographic effects (rapid cooling of rising air masses) which results in increasing rainfall with increasing elevation.
What are the requirements for orographic rainfall to be experienced?
Answer: the west coast of india and the step slope of western ghats are the chief requirements for orographic rainfall to be experienced.
Where would you be most likely to find orographic precipitation?
Some places of the world are well known for their orographic precipitations. Mountain rainfall is common on oceanic islands like Hawaii and New Zealand. In these places, much of the prevalent rainfall is on windward sides and the opposite regions remain comparatively dry, sometimes almost desert-like.
What are some examples of orographic precipitation?
Precipitation caused or enhanced by one of the mechanisms of orographic lifting of moist air. Examples of precipitation caused by mountains include rainfall from orographic stratus produced by forced lifting and precipitation from orographic cumuli caused by daytime heating of mountain slopes.
Where does orographic precipitation occur?
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.
At which setting will orographic lifting occur?
Orographic lifting occurs when air rises and cools as it travels up the windward side of a mountain. As air cools, saturation point decreases. This means cold air holds less water vapor. At the dew point temperature, the air is "full," and water vapor begins to condense.
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.
Which area orographic rainfall occurs?
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. Thus, Mahabaleshwar lying on the windward side receives more than 250 cm of rainfall, while Pune on the leeward side records less than 70 cm of rainfall.
Where would you be most likely to find Orographic precipitation?
Some places of the world are well known for their orographic precipitations. Mountain rainfall is common on oceanic islands like Hawaii and New Zealand. In these places, much of the prevalent rainfall is on windward sides and the opposite regions remain comparatively dry, sometimes almost desert-like.
What causes orographic lifting?
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation.
Where is orographic rainfall found?
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.
What is orographic rainfall in geography?
Orographic rainfall also called orographic precipitation or snow. 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.
How orographic precipitation is formed?
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.
Which of the following processes can be called orographic lifting?
Which of the following processes can be called orographic lifting? Air is forced to rise over a mountainous barrier.
When and where do orographic occur?
The moist adiabatic lapse rate (~0.6C/100m) occurs above 2000m. The dry adiabatic lapse rate (1C/100m) occurs below 2000m. 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.
Where does orographic lifting occur?
Orographic lifting occurs when air rises and cools as it travels up the windward side of a mountain. As air cools, saturation point decreases. This means cold air holds less water vapor.

Where does orographic cloud generally form?
As airflow encounters a mountain or hill, it is forced to rise; this is referred to as orographic lift. If the flow is sufficiently humid, clouds form on the windward side of mountains and are called orographic clouds (Figure 2). The type of cloud that forms depends on the air stability and moisture content.
How are orographic clouds formed?
Orographic clouds develop in response to the forced lifting of air by the earth's topography (mountains for example). Air passing over a mountain oscillates up and down as it moves downstream.
