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.

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.

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 ...
