WEATHER&METEOROLOGY
A rising bubble of warm air which forms at the surface where heating is large and dry convection is occurring under superadiabatic conditions. Clouds start out as thermals before they reach their convective (lifting) condensation level but not all thermals become clouds. This is because the surface characteristics (supplying the thermal) are either too dry or too cold for the thermal to reach saturation aloft.

Air rising or falling due to temperature differences thus creating pockets of high pressure. Useful in soaring.

Thermal Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
A thermal column (or thermal) is a column of rising air in the lower altitudes of the Earth's atmosphere. Thermals are created by the uneven heating of the Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection. The Sun warms the ground, which in turn warms the air directly above it. Dark earth, urban areas and roadways are good sources of thermals.
