Interpret weather radar reflectivity (dBZ) into precipitation type and rate.
输入雷达反射率因子(dBZ),利用 Z-R 关系估算降水强度,并判别回波类型与对流强度。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Reflectivity factor | dBZ = 10 log Z | Radar meteorology |
| Z-R relation | Z = 200R^1.6 | M&P 1948 |
| dBZ thresholds | 20 light / 35 mod / 45 heavy / >55 hail | NWS radar guide |
| Echo top | ET >12 km deep convection | Radar product spec |
| Attenuation | X/C band needs correction | QX/T radar calibration |
| Ground clutter | Filter low-elevation clutter | QC spec |
输入天气雷达反射率因子(dBZ),依据 Marshall-Palmer Z-R 关系反演降水强度,并按 dBZ 量级判别层状云、对流云、暴雨及冰雹等回波类型,为强对流天气识别提供参考。
