A weather (state of atmosphere) front is a boundary separating two masses of air of different ... When a front becomes stationary, and the density contrast across the frontal boundary vanishes, the ...

Lifting Mechanisms | Climate Education Modules for K-12


Jun 25, 2012 ... Lifting mechanisms are forms of lift that cause air to rise. In this topic we cover orographic lift, frontal lift, convergence, and convective lift.

Effects of Frontal Lifting: on forecasted precipitation


Effects of Frontal Lifting. on forecasted precipitation. Forecast Tip: If there is sufficient moisture in the air and a forcing mechanism like a cold front (for example) is ...

Air Lift: Definition & Processes - Video & Lesson Transcript | Study.com


Another way that air is lifted is through frontal lifting. A front is where two different air masses meet, so frontal lifting is when one air mass along a front gets lifted ...

The third process is frontal lifting. Here a moving, cooler air mass pushes its way under and lifts a warmer air mass. Again, this lifting action can produce cumulus ...

The forced ascent of the warmer, less-dense air at and near a front, occurring whenever the relative velocities of the two air masses are such that they converge ...

7(r) Air Masses and Frontal Transitional Zones - Physical Geography


The sloping of warm air over the cold air leads to a forced uplifting (frontal lifting) of the warm air if one air mass is moving toward the other. In turn, this uplifting ...

8(e) Cloud Formation Processes - Physical Geography


Convergence or frontal lifting takes place when two masses of air come together. In most cases, the two air masses have different temperature and moisture ...

Atmospheric Instability and Cloud Development due to frontal lifting


Atmospheric Instability and Cloud Development - Frontal Lifting. Another lifting mechanism is by fronts -->>. if air is lifted into a stable layer: stratus or ...

Lifting Along Frontal Boundaries: when air masses interact


Lifting Along Frontal Boundaries. when air masses interact. Lifting also occurs along frontal boundaries, which separate air masses of different density.
