What type of SIGMET addresses severe turbulence and icing conditions?

1. Convective SIGMET

2. Non-Convective SIGMET

3. Routine SIGMET

4. Special Weather Statement

The correct answer is: Non-Convective SIGMET

The correct answer focuses on Non-Convective SIGMET, which is specifically designed to address significant weather phenomena outside of convective activities. Severe turbulence and icing conditions are often associated with non-convective weather patterns, such as those caused by frontal systems, jet streams, or winter storms. Non-Convective SIGMETs provide critical information to pilots about adverse weather conditions that could impact flight safety, especially in terms of turbulence and icing, which can pose serious hazards during flight operations. They typically cover a wider scope of weather phenomena, making them essential for ensuring that pilots are aware of these potentially dangerous conditions. In contrast, Convective SIGMETs are primarily issued for thunderstorms and related phenomena, which makes them less relevant for severe turbulence and icing that are not directly associated with convection. Routine SIGMETs do not specifically pertain to the urgent severe conditions that Non-Convective SIGMETs address, and Special Weather Statements typically provide broader updates rather than the specific, urgent warnings critical for safety in these scenarios.
