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

Figure 15

Vertical cross sections along EF (shown in Figure 2(a)) of radar echo (shadings, unit: dBZ), equivalent potential temperature (solid lines, unit: K blue lines for ≤350 K and black lines for >350 K), and winds at various times (a) 1400 UTC, (b) 1600 UTC, (c) 1700 UTC, (d) 1800 UTC, (e) 1900 UTC, and (f) 2100 UTC. Y-axis indicates the height (unit: km). X-axis shows the distance along the direction shown by BD in Figure 2(a) to the western boundary (AB) of the key rainstorm area (unit: km).
