The effect of reported high-velocity small raindrops on inferred drop size distributions and derived power laws
reported high-velocity small raindrops inferred drop size distributions derived power laws
2010/8/16
It has recently been shown that at high rainfall intensities, small raindrops may fall with much larger velocities than would be expected from their diameters. These were argued to be fragments of rec...
