Reduction of precipitation during heatwaves and temporal distribution of selected heatwaves throughout the summer. Daily rainfall ($\mathrm{mm}/\mathrm{day}$) against daily mean temperature (${}^{\circ }\mathrm{C}$) of summer days in June, July, August from 1979 to 2018 in a Northern Europe, b Western Europe, and c Southern Europe. Color shaded points in a blue, b green, and c red are selected heatwaves dates. $P_{80}$ is the daily mean temperature threshold for each region, ${\mu }_{\mathit{rcs}}$ is daily mean precipitation during climatological summer, ${\mu }_{\mathit{rhw}}$ is daily mean precipitation during heatwaves days, and $N_{\mathit{dhw}}$ is the total number of heatwaves days. d Selected periods of heatwaves for each region
