Occur when warm air moves over the top of cooler air at the surface.

Waterspout
51
Caused by a thin layer of standing water that separates the tires from the runway.

52
This turbulence is often defined as turbulence below 15,000ft. MSL. Originates due to surface heating or friction within a few thousand feet of the ground.

53
This turbulence is often experienced in the traffic pattern when the winds forms eddies as it blows around hangars, stand of trees, or other obsturctions.
Mechanical Turbulence
54
This turbulence is also referred to as thermal turbulence, is typically a daytime phenomenon that occurs over land in fair weather when winds are light. Caused by vertical air currents or thermals that develop in air heated by contact with the warm surface below.
Convective Turbulence
55
This turbulence occurs in the narrow zone just ahead of a fast-moving cold front where updrafts can reach 1,000ft./min.
Frontal Turbulence
56
This turbulence is commonly thought of as a high altitude phenomenon. Usually encountered above 15,000ft. however it can take place at any altitude and is often present with no visual warning.
