Which landform exists because of the rain shadow effect?
A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked.
Which of the following is responsible for the rain shadow effect?
Wind and moist air are drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the “rain shadow”.
What effect is caused by a rain shadow?
???? ?? ??? ???? ?????? ??????? An area having relatively little precipitation due to the effect of a topographic barrier, especially a mountain range, that causes the prevailing winds to lose their moisture on the windward side, causing the leeward side to be dry.
What is the opposite of rain shadow?
A rain shadow region is the leeward side which is opposite to the windward side.
What is another word for rain shadow?
Other relevant words (noun): fohn, foehn.
What is 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.

Why is orographic rainfall important?
In orographic precipitation, the important fact is that a landform acts as a wedge or barrier over which moist air is lifted and cooled to the dew point, and clouds release some moisture as precipitation. Orographic precipitation may occur in downpours, but it usually takes the form of general rains.
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 best describes the orographic effect?
What Is the Orographic Effect? As a weather system moves over land, it follows the topography of the terrain. The air might rise up over mountains or sink down through valleys. Orographic effect is the term used to describe changes to air flow when the topography of the land forces air upward.
Is cyclone a rain?
Cyclones: bringing clouds and precipitation. A cyclone is an area of low pressure around which the winds flow counterclockwise in the northern hemisphere. Air converges into a low pressure center which causes air to rise. The rising motion may produce clouds and precipitation.
What is called cyclonic rain?
Cyclonic or Frontal rain: This type of rainfall occurs when warm and cold air meets each other. Since warm air is lighter, it rises above the cold air. The rising air is then cooled beyond the saturation point resulting in heavy rainfall. Such rainfall lasts only for few hours.
Why is there a lot of rain during typhoon?
Answer: Rainfall is more common near the center of tropical cyclones overnight. Over land, outer bands are more active during the heating of the day, which can act to restrict inflow into the center of the cyclone. Recent studies have shown that half of the rainfall within a tropical cyclone is stratiform in nature.
Is the air in the center of a cyclone subsiding or rising?
Is the air in the center of the cyclone subsiding or rising? The air is rising and precipitation occurs along the path of the storm because it follows cloud formation.
Is the eye of a storm high or low pressure?
A characteristic feature of tropical cyclones is the eye, a central region of clear skies, warm temperatures, and low atmospheric pressure.
Why is the eye of a storm low pressure?
So you have a tremendous volume of air converging from 360 degrees around the hundreds of miles of the storm, all converging on the eye and spiraling up with an intense updraft, creating a very low pressure near the surface in the eye/core.
Why is the eye the calmest part of the storm?
Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach it. This convergence causes the air to actually sink in the eye.
