The definition of geometric parameters of precipitation clouds.
| | Symbol | Geometric meaning |
| | L(km) | The length of precipitation cloud | | W(km) | The width of precipitation cloud | | α | α describing horizontal shape of precipitation cloud, α = W/L | | S(km2) | The area of precipitation cloud, sum of all area of rain pixels | | β | The filling ratio of precipitation cloud, the ratio of precipitation cloud S to the fitted MBR area | | Hmax(km) | The maximum echo top height among rain pixels in precipitation cloud | | Havg(km) | The mean echo top height averaged among rain pixels in precipitation cloud | | γmax | The maximum spatial morphology, γmax = Hmax/L | | γavg | The mean spatial morphology, γavg = 2 Havg/(L + W) |
