A decrease in storm activity over large parts of the US, Europe, Russia, and China is found to influence weather extremes—cold ones in winter, hot or dry ones in summer. This is now shown in a study by scientists from the Potsdam Institute for Climate Impact Research. The observed changes in storm activity are likely related to changes in other atmospheric dynamics like the jet stream—strong westerly winds circling the Northern hemisphere high up in the sky.
