Diurnal Variation Characteristics of Raindrop Size Distribution Observed by a Parsivel² Disdrometer in the Ili River Valley

Figure 7

Composite raindrop spectra for the five rainfall rate classes at different time periods of the day. The rainfall rate intervals are (in mm·h⁻¹) (a) 0.1 ≤ R < 0.5, (b) 0.5 ≤ R < 1, (c) 1 ≤ R < 2, (d) 2 ≤ R < 5, and (e) R ≥ 5.
