Which weather term stands for Significant Meteorological Information?

Explanation:
SIGMET stands for Significant Meteorological Information and is the aviation weather advisory used when weather phenomena could threaten flight safety. It covers significant weather not tied to thunderstorms, such as severe icing, severe turbulence, dust or sandstorms reducing visibility, volcanic ash clouds, and tropical cyclone activity. A separate product called Convective SIGMET handles weather tied to thunderstorms. Other options aren’t weather terms: SIDS is a medical condition, Significant weather prognostic isn’t an official term, and Sensitive altimeter isn’t a weather designation.
