What happens when warm moist air rises over a mountain?

As the relatively warm, moist air rises over the windward side of the mountains, it cools and contracts. If the air is humid, it may form clouds and drop rain or snow. When the air sinks on the leeward side of the mountains, it forms a high pressure zone.

What happens when moist warm air rises?

If warm moist air rises, it will expand and cool. As it cools, the relative humidity will increase and water will condense. It can then fall back to the earth as precipitation. … As air rises, it expands because there is less atmospheric pressure at higher altitudes.

What happens to warm moist air as it moves up a mountain Why think about change in density temperature and rainfall?

As warm, moist air rises up the side of the mountain – known as the windward side – it expands (because there’s less pressure) and it therefore cools. … It’s also why the windward side is rainy and the leeward side is dry.

What is formed when warm moist air is pushed over a mountain?

As moist winds blow toward a mountain, it up glides and this causes the air to rise and cool. The cooling of the air from rising causes to meet up with the dew point temperature. Fog forms on top of the mountains. Valley Fog: Valley fog forms in the valley when the soil is moist from previous rainfall.

What eventually happens to moist air if it rises high enough?

What eventually happens to moist air if it rises high enough? The moist air will eventually become tiny droplets or ice crystals, forming a cloud. … As it gets higher in the atmosphere, it cools causing it to not be able to hold as much moisture as before.

What happens when air rises over a mountain?

As air rises over a mountain it cools and loses moisture, then warms by compression on the leeward side. The resulting warm and dry winds are Chinook winds. The leeward side of the mountain experiences rainshadow effect.

What are the 4 types of fog?

There are several different types of fog, including radiation fog, advection fog, valley fog, and freezing fog.

What happens when air cools?

What happens when air is heated or cooled? … So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.

Is fog a precipitation?

Precipitation. Precipitation fog forms as precipitation falls into cold, drier air below the cloud and evaporates into water vapor. The water vapor cools and at the dew point it condenses. When it condenses, it creates fog.

What are 4 ways air can be forced upward?

– There are four lifting mechanisms that form clouds: Orographic Lifting, Convection, Convergence, and Updraft. – Orographic lifting is when air cannot go through a mountain, and so it flows over it. – Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move.

What are the three conditions reasons that causes air to rise?

The atmosphere and the weather

  • Surface heating and free convection.
  • Horizontal Convergence of surface air and/or Horizontal Divergence of air near the top of the troposphere.
  • Topography (mountains)
  • Uplift along weather fronts.
