What are the sides of a mountain called?

In all circumstances in which the terms are used the windward side of the reference point is the one that faces the prevailing wind. The leeward—or “lee”—side is the one sheltered from the wind by the reference point. Windward and leeward aren’t frivolous terms.

What is the wet or green side of a mountain range called?

The windward side is the side of the mountain that the wind encounters. The land on the windward side of a mountain can be lush and green as a result of this precipitation. On the other side of the mountain the leeward side the air rapidly descends and becomes warmer once more.

What are the names of the wet and dry sides of the mountain?

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. In a rain shadow it’s warm and dry.

Is the leeward side cooler?

Rain. As condensation occurs it releases heat into the surrounding air. … As the air continues to descend towards sea level atmospheric pressure increases which causes a temperature increase. Because of all of this (scientifically called adiabatic warming) the leeward side is generally warmer and drier.

Which side of mountain gets more rain?

windward side
Much of airborne moisture falls as rain on the windward side of mountains. This often means that the land on the other side of the mountain (the leeward side) gets far less rain—an effect called a “rain shadow”—which often produces a desert.

What is the leeward side of a mountain?

Leeward (/ˈliːwərd ˈljuːərd/) is the direction downwind from the point of reference i.e. along the direction towards which the wind is going. The leeward region of mountains generally remains dry as compared to the windward region.

What is the windward side of a mountain?

When air runs into a mountain the side of the mountain that it hits first is called the windward side. This is where air is forced to rise and this is the side of the mountain that often sees the heaviest precipitation.

Why is the windward side of a mountain Wet?

Once the damp air makes landfall on an island it ascends hills and mountains to form condensation clouds and precipitation. As the air moves to the other side of the island it warms up and dries out. Thus an island’s windward side is wetter and more verdant than its drier leeward side.

What is a rain shadow desert?

Rain shadow deserts are created when mountain ranges lie parallel to moist coastal areas. Prevailing winds moving inland cool as air is forced to rise over the mountains. Carried moisture falls on slopes facing the winds. When the winds move over the crest and down the far side they are very dry.

What is a Convectional rainfall?

Convectional rainfall

When the land warms up it heats the air above it. … As the air rises it cools and condenses. If this process continues then rain will fall. This type of rainfall is very common in tropical areas but also in areas such as South East England during warm sunny spells.

What is mountain 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.

How do mountains cause rain?

Mountains can have a significant effect on rainfall. When air reaches the mountains it is forced to rise over this barrier. As the air moves up the windward side of a mountain it cools and the volume decreases. As a result humidity increases and orographic clouds and precipitation can develop.

What is the relative humidity when it rains?

Most of the time when it is raining the relative humidity is 90-99 percent but not often is it 100 percent. Clouds form when invisible water vapor gas condenses into visible water droplets and rain occurs when droplets grow too large to be supported in the air and they fall.

Where is a rain shadow?

A rain shadow is a dry area on the side of a mountain opposite to the wind. We call this dry side of the mountain the leeward side. If wind is approaching from the west the rain shadow is on the east. If the wind is approaching from the east the rain shadow is on the west.

Why is it dry on the east side of the mountain?

On the east side (or lee side) of the mountains this same air having precipitated much of its moisture continues eastward and down the mountain slope. This sinking air warms what moisture is left evaporates and dry conditions remain. This is what is called the “rain shadow” effect.

Which side of the mountain has warm moist air?

windward side

Mountains have two sides: windward and leeward. The windward side faces the wind and typically receives warm moist air often from an ocean.

What is a subtropical desert?

Subtropical deserts are very hot and dry in the summer and cooler but still dry in the winter. Rainfall happens in short bursts. The air is so hot and dry in these deserts that sometimes rain evaporates before it even has a chance to hit the ground!

What is the rainshadow effect?

Glossary Term. Rain shadow effect. The region on the lee (sheltered) side of a mountain or mountain range where the precipitation is noticeably less than on the windward side because the moisture-bearing air mass loses most of its moisture on the windward side before reaching the lee side.

What are prevailing winds?

Prevailing winds are winds that blow consistently in a given direction over a particular region on Earth. Due to factors such as uneven heating from the Sun and the Earth’s rotation these winds vary at different latitudes on Earth.

What is a relief rainfall?

Relief rainfall occurs when warm moist air from the Atlantic Ocean rises up over mountains. When the warm air rises it cools and condenses to form clouds which bring rain. Once the air has passed over the mountains it descends and warms.

What are convective showers?
