Convective temperature - The temperature to which air must be heated to generate convection solely by heating. The air will have a dry adiabatic lapse rate from the surface to the LFC.

Convective Temperature - The approximate temperature that the air near the ground must warm to in order for surface-based convection to develop, based on analysis of a sounding. See Fig. 6.

Convective Temperature It is the surface temperature that must be reached to start the formation of convective clouds by solar heating of surface-air layer.

Calculation of the convective temperature involves many assumptions, such that thunderstorms sometimes develop well before or well after the convective temperature is reached (or may not develop at all).

[Slang] A sounding characterized by extreme instability but containing a cap, such that explosive thunderstorm development can be expected if the cap can be weakened or the air below it heated sufficiently to overcome it (the convective temperature).

strong vertical motions are produced by displacement of a parcel of air that accelerates upward when the parcel is moved upward, or downward when the parcel is moved downward. Usually found in regions of the atmosphere where a convective temperature ...

and dew point (and often winds) above a fixed location. Soundings are used extensively in severe weather forecasting, e.g., to determine instability, locate temperature inversions, measure the strength of the cap, obtain the convective temperature, ...
