What is the purpose of issuing Convective SIGMETs?

The purpose of issuing Convective SIGMETs is to provide warnings about potential severe weather that can significantly impact flight safety. These alerts focus on specific hazardous weather phenomena associated with convective activity, such as thunderstorms, severe turbulence, wind shear, and hail. By informing pilots of these dangers, Convective SIGMETs play a crucial role in helping them make informed decisions regarding flight routes and safety measures to mitigate the risks associated with severe weather conditions.

The other options do not align with the function of Convective SIGMETs; they either downplay the potential dangers of flight conditions or pertain to unrelated aspects of weather reporting.
