Cloud‐Radiative Impact on the Regional Responses of the Midlatitude Jet Streams and Storm Tracks to Global Warming
Previous work demonstrated the strong radiative coupling between clouds and the mid‐latitude circulation. Here, we investigate the impact of cloud‐radiative changes on the global warming response of the mid‐latitude jet streams and storm tracks in the North Atlantic, North Pacific and Southern Hemis...

Previous work demonstrated the strong radiative coupling between clouds and the mid‐latitude circulation. Here, we investigate the impact of cloud‐radiative changes on the global warming response of the mid‐latitude jet streams and storm tracks in the North Atlantic, North Pacific and Southern Hemisphere. To this end, we use the ICON global atmosphere model in present‐day setup and with the cloud‐locking method. Sea surface temperatures (SST) are prescribed to isolate the circulation response to atmospheric cloud‐radiative heating. In the annual mean, cloud‐radiative changes contribute one‐ to two‐thirds to the poleward jet shift in all three ocean basins, and support the jet strengthening in the North Atlantic and Southern Hemisphere. Cloud‐radiative changes also impact the storm track, but the impact is more diverse across the three ocean basins. The cloud‐radiative impact on the North Atlantic and North Pacific jets varies little from season to season in absolute terms, whereas its relative importance changes over the course of the year. In the Southern Hemisphere, cloud‐radiative changes strengthen the jet in all seasons, whereas their impact on the jet shift is limited to austral summer and fall. The cloud‐radiative impact is largely zonally‐symmetric and independent of whether global warming is mimicked by a uniform 4 K or spatially‐varying SST increase.
