What does "T" stand for in temperature reporting in METAR?

In METAR reports, the "T" specifically stands for "Temperature," indicating the current temperature of the air measured in degrees Celsius. This designation is part of a more complex temperature and dew point reporting system utilized in aviation weather observations. When you see "T" followed by a numerical value, it provides the essential temperature reading that pilots and meteorologists need for flight planning and safety conditions.

The choice indicating "Total" does not apply here since it does not relate to temperature. "True" is not relevant either, as "T" does not denote a truth value in this context. Lastly, "Thunderstorm" would not fit into this specific reporting framework, as METAR distinguishes between temperature, humidity, wind, and other weather phenomena separately. Therefore, understanding that "T" directly corresponds to "Temperature" helps clarify not only this aspect of METAR reports but also the importance of accurate temperature readings in aviation weather assessments.
