Fig. 4: Himalayan trend of ERA5-Land diurnal (8:00–20:00) accumulated precipitation in the warm season (from May to October, during 1994–2020).
From: Local cooling and drying induced by Himalayan glaciers under global warming
a, The map reports the glacier mask used in ERA5-Land and the −0.01 °C yr−1 Tmax cooling trend isolines (Fig. 1). Cold and warm colours represent decreasing and increasing precipitation trends (% yr−1), respectively. The black line indicates their significance (P < 0.05). Three regions of interest have been selected to show the trend magnitudes for precipitation and temperature (from Fig. 1a) along the elevation gradient. b–d, The trend distribution is shown for Lahaul-Spiti (b), Western Himalaya (c) and Central-Eastern (d) subregions, respectively (blue points for precipitation trends, orange points for Tmax trends). The same trend, but considering both diurnal and nocturnal precipitation, is reported in Supplementary Fig. 21.
