Final answer:

A current CONVECTIVE SIGMET forecasting thunderstorms alerts aircraft to potential severe turbulence or severe thunderstorms that are significant hazards to flight operations.

Step-by-step explanation:

When a current CONVECTIVE SIGMET forecasts thunderstorms, it indicates that there may be significant hazards to aircraft in the form of severe turbulence or thunderstorms that are severe enough to warrant attention by all aircraft in the vicinity. Thunderstorms are associated with convection, a process where warm, moist air rises and cools, leading to the formation of clouds and precipitation. These storms can grow to formidable sizes, sometimes penetrating into the stratosphere, driven by the energy released during the condensation phase change of water vapor.

Thunderstorms are a serious concern for aviation because they are often accompanied by other hazardous phenomena such as heavy rain, lightning, hail, strong winds, and in some conditions, can even precipitate the formation of tornadoes. It is important for pilots and flight planners to monitor these SIGMETs closely, as they provide critical safety information that could affect flight paths and operations.
