Cold, hot or dry: Persistent weather extremes associated with decreased storm activity

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. —> Read More
