图4 2020—2021年暖季08:00起报的36 h时效24 h累积降水量在小雨(a、b、c)、中雨(d、e、f)、大雨(g、h、i)和暴雨(j、k、l)量级的降水频率预报偏差分布(单位:%) [(a、d、g、j)为 CNTL-观测,(b、e、h、k)为 PM-观测,(c、f、i、l)为 MEAN-观测] |
Fig.4 Frequency prediction deviations of light rain (a, b, c), moderate rain (d, e, f), heavy rain (g, h, i) and rainstorm (j, k, l) for 24 h accumulated precipitation forecast of 36 h lead time starting at 08:00 in the warm season from 2020 to 2021 (In fig.a, fig.d, fig.g and fig.j, the value is for CNTL minus observation; In fig.b, fig.e, fig.h and fig.k the value is for PM minus observation; In fig.c, fig.f, fig.i and fig.l the value is for MEAN minus observation) |
