Which feature is represented by the Tropopause LEVEL symbol on a SIGWX chart?

Explanation:
The symbol on a SIGWX chart is signaling the altitude of the tropopause in that area. The tropopause is the boundary between the troposphere, where most weather happens, and the stratosphere. Its height changes with latitude and season, generally being higher in the tropics and lower toward the poles. By marking the tropopause level, the chart communicates where the upper boundary of the weather layer sits, which helps pilots understand the vertical extent of storms, cloud tops, and the overall upper-air environment. This symbol is not about a surface cold front, a change in jetstream wind speed at a specific level, or anything related to radioactive materials.
