‘Mega heat waves’ strengthened by interaction between soil moisture, atmospheric pressure and temperature

A new study has found that a self-reinforcing interaction between temperature, soil moisture and atmospheric pressure is being triggered at high temperatures, making extreme heat waves 10% hotter than they would otherwise be. The study was published in Science Advances and led by the Potsdam Institute for Climate Impact Research (PIK) and the International Institute for Applied Systems Analysis (IIASA).
