what happens when an air mass is pushed up and over a mountain range
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 happens to air as it moves over a mountain range?
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 is it called when air is forced over a mountain?
Orographic Lifting Same as Upslope Flow; occurs when air is forced to rise and cool due to terrain features such as hills or mountains.
What happens when air is pushed up and over a mountain range?
When the wind blows across a mountain range, air rises and cools, and clouds can form. Some clouds form when air encounters a mountain range or other types of terrain.
What happens when an air mass meets a mountain?
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 happens to the airflow as it hits a mountain?
Mountains have two sides: windward and leeward. The windward side faces the wind and typically receives warm, moist air, often from an ocean. As wind hits a mountain, it is forced upward and begins to cool. Cool air reaches its dew point more quickly, and the result is rain and snow.Jun 19, 2019
Can air masses move over mountains?
Topography can play a crucial role in the modification of air masses. For example, the Rocky Mountains cause flow from the west to be lifted over the mountains. The originally mP air loses its moisture as it precipitates, leaving dry air to move eastward.
What happens to an air mass as it descends?
Answer and Explanation: A descending air mass is drier because the air becomes warmer as it moves down in the atmosphere. Therefore, the humidity in the air mass decreases as the temperature increases which produces drier air. This all happens in relation to atmospheric pressure.
What happens to an air mass as it runs into a mountain?
When air is confronted by a mountain, it is forced up and over the mountain, cooling as it rises. If the air cools to its saturation point, the water vapor condenses and a cloud forms. Heating of the mountain slopes by the Sun also causes air to rise upward.
What does an air mass do when it encounters a mountain range?
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 air masses to move?
Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.
What happens when two air masses collide quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. How is a warm front produced? A warm front forms when warm air moves into an area formerly covered by cooler air.
What happens to a moving warm air mass when it encounters a mountain range?
Solution: When warm air hits the mountain, it has to rise to bypass the mountain. When it rises to a higher part of the atmosphere, it causes that air to cool.
