Fig. 11: Schematic diagram of how the correct TP SPV simulation improved the downstream precipitation prediction at an extended-range in 2022.

The correct simulation of TP SPV and associated overhead heating in June 2022 improves the prediction of low-level water vapor transport and of middle- and upper-level synoptic waves, both of which favor the correct prediction of strong ascending motions related to strong precipitation.
