What plays a role in causing a rain shadow?

Formation of a Rain Shadow

When orographic precipitation occurs, it depletes this air of moisture. By the time the air passes over the mountains, it is relatively dry. As this dry air moves down the lee side of a mountain range, it warms and becomes capable of retaining even more water vapor.

What role does Latent Heat play in the rain shadow effect?

As water molecules leave the rising air parcel as precipitation, most of the latent heat of condensation stays with the parcel’s molecules. As it sinks along the mountain’s downwind side, the air becomes warmer and drier than when it began its ascent.

What are the 4 properties of air that determine how it circulates in the atmosphere?

Air has four properties that determines its movement: Density- less dense air rises, denser air sinks. Water vapor capacity- warm air has a higher capacity for water vapor than cold air. Adiabatic heating or cooling- as air rises in the atmosphere its pressure decreases and the air expands.

What contributes to the unequal warming of the earth?

Solar heating of the Earth’s surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces. … This differential heating is passed on to the air above by conduction which causes air expansion and changes in pressure.

What 3 things do you need to get a rain shadow effect?

height above or below sea level. series or chain of mountains that are close together. all forms in which water falls to Earth from the atmosphere. dry land on the side of a mountain facing away from prevailing winds.

What effect is caused by a rain shadow quizlet?

? 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.

How does latent heat affect weather?

Latent heat supplies weather energy. As water condenses, latent heat from the water molecule is released into the air, heats the air, makes it lighter, and makes it rise fast. As the air rises, more air flows in and promotes storms.

What three factors affect how air flows?

The three major factors that determine how air circulates in the lower atmosphere are uneven heating of the earth’s surface by the sun, rotation of the earth on it’s axis, and the properties of air, water, and land.

What three factors affect how air flows in our atmosphere?

Air flows from areas of higher pressure to areas of lower pressure.  The unequal heating of Earth’s surface generates pressure differences. Solar radiation is the ultimate energy source for most wind.  Three factors combine to control wind: pressure differences, the Coriolis effect, and friction.

How the properties of air water and land affect global air circulation?

Describe how the properties of air, water, and land affect global air circulation. Prevailing Winds blow over the ocean surface and produce currents. The Oceans absorb heat from the earth’s air circulation patterns; mostly in tropical regions. … As prevailing winds blow over the ocean surface, it produces currents.
