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

Figure 12

Diurnal variations of (a) temperature (°C), (b) relative humidity (%), (c) wind speed (m·s⁻¹), and (d) CAPE (J·kg⁻¹) during the observation period calculated from automatic weather station data and ERA5 reanalysis data. The central line of the box indicates the median, and the bottom and top lines of the box indicate the 25th and 75th percentiles, respectively. The bottom and top of the dashed vertical lines indicate the 5th and 95th percentiles, respectively. Red solid lines represent the mean values.
