Short summary
By using high concentrations of 7Be as an indicator, we clarify fast descent routes from the stratosphere to Earth's surface in Japan. Most routes arise from high latitudes through the following processes: descent associated with a tropopause fold, southward movement with slow descent at the rear side of a strong trough, and strong descent at the south edge of the trough.
The reason that high concentrations of 7Be occur most frequently in spring is explained.
By using high concentrations of 7Be as an indicator, we clarify fast descent routes from the...
