Characteristic Features of the Evolution of a Meiyu Frontal Rainstorm with Doppler Radar Data Assimilation

Figure 7

Temporal evolution of hourly precipitation (unit: mm·h⁻¹) averaged over all grids along AB (shown in Figure 2(a)) in the key rainstorm area (the white frame shown in Figure 2(a)). X-axis indicates the distance (unit: 10 km) to the western boundary (i.e., AB) of the key rainstorm area along the BD direction (shown in Figure 2(a)). Y-axis shows the forecasting time (unit: hour) from 0000 UTC 4 -0000 UTC 5 July.
