12. Precipitation, Air Masses, and Fronts

Warm front by the Noah Ark Exhibition, Hong Kong, China. June 2011.


Frontal Precipitation


Frontal Precipitation is the frontal movement created by the uplift of warm air, which is then cooled and the water vapor undergo condensation. One of the types is the cold front, where the cold air wedge-like movement forces the warm air to rise and condense into a huge cumulonimbus creating a dramatic rainfall. Warm front allows the lighter warm air to rise and spreading out the rain clouds along the increasing gentle slope above the cold air, overriding the cooler air. From my photo, my background resembles a warm front since the rain cloud is not as dramatic as it seems to be and the rain was not too hard.
