Fig. 5: Effects of the marine heatwave on near-surface temperature and wind over land.

a 1.5 m air temperature difference averaged over the British Isles between a regional atmospheric simulation with the observed marine heatwave (ATMostia, with OSTIA SSTs) and without (ATMclim, with climatological OSTIA SSTs). b Wind averaged over the British Isles in both simulations (ATMostia in full line and ATMclim in dashed line). c Map of 1.5 m air–temperature differences (ATMostia–ATMclim) averaged from 19 to 25 June (red area on a, b).
