If a thunderstorm ended at 2057UTC and the current time is 2106UTC, how is this information encoded?

The correct encoding of the information regarding the thunderstorm ending time is based on the international meteorological standards for identifying thunderstorm events. The term "TSE" is specifically used to denote the ending of a thunderstorm.

In this scenario, the thunderstorm ended at 2057 UTC, and therefore, the code "TSE2057" effectively communicates that the thunderstorm has ceased at that specific time. This coding format helps meteorologists and pilots reference weather conditions quickly and accurately, ensuring clarity in weather data reporting.

The other options use variations of the "T" prefix that may imply related but different meanings. For instance, "TST" generally denotes the occurrence of a thunderstorm, while "TSO" and "THU" do not correspond to established conventions within thunderstorm reporting.
