Definition Of Orographic Lifting

Definition Of Orographic Lifting. This simple concept is such a powerful lifting force in the atmosphere that it is likely responsible for the majority of the snow that falls in big mountains. Occurs when air is forced to rise and cool due to terrain features such as hills or mountains.

Several thermodynamic variables change when air rises. Orographic lift is an adiabatic process, which means that all of the changes that happen within an air parcel occurs only in the parcel through changes in temperature and how much moisture can be condensed within the parcel.

In convective lift, moist air is warmed as it moves over warm ground. If the cooling is sufficient, water vapor condenses into clouds.

Occurs When Air Is Forced To Rise And Cool Due To Terrain Features Such As Hills Or Mountains.

As air rises over mountains, it cools and water vapor condenses. When air is forced to rise over a land mass of higher elevation (mountain) and in the process, expands, cools, condenses, and forms clouds. The rising air leads to a drop in temperature, which results in condensation, cloud formation, and.

Of or relating to mountains especially : The orographic effect occurs when air masses are forced to flow over high topography. This is a fancy name with a very simple meaning.

If The Cooling Is Sufficient, Water Vapor Condenses Into Clouds.

When this type of lifting occurs the land forces the air to move to a higher elevation. Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. The air cools, forms clouds, and rains, leaving the lee side dry.
