What does "TS" indicate in METAR reports?

  1. Thunderstorms

  2. Temporary Signals

  3. Turbulence Severity

  4. Terminal Status

The correct answer is: Thunderstorms

In METAR reports, "TS" is the abbreviation for thunderstorms. Aviation weather reports are critical for pilots and air traffic controllers, as they provide important information about current weather conditions at airports. Thunderstorms are significant because they can create hazardous flying conditions, including strong winds, turbulence, severe precipitation, and lightning. Recognizing "TS" in a METAR report alerts pilots to the potential dangers associated with thunderstorms, allowing them to adjust flight plans or approaches accordingly. Understanding this abbreviation is crucial for flight safety, as thunderstorms can develop rapidly and impact visibility and aircraft performance. Familiarity with METAR codes, including "TS," is essential for effective communication and situation awareness in aviation operations.
