Different Types of Rainfall - Convectional, Orographic, Cyclonic Rainfal...


All three of these processes are mechanisms by which moist air masses are uplifted and chilled, with the chilling process triggering condensation and precipitation.

Convectional Lifting - Thermal Convection provides the uplift, explained near the beginning of the video.  (Note the textbook typo.)

Orographic Lifting - Interaction between moist air masses and mountains provides the uplift on the Windward side.  The Rain Shadow Effect is explained beginning at approximately 5:19 in the video.  (Recall that the Rain Shadow Effect is the primary "cause" of the four North American Deserts.)

Cyclonic Lifting - Interaction between dry Cold Air Masses and moist Warm Air Masses is explained at approximately 6:37 in the video.



Other considerations - heat moves towards cool areas
