On the role of Ural Blocking in driving the Warm Arctic–Cold Siberia pattern

We use reanalysis data to substantiate the role of Ural blocking (UB) in driving the Warm Arctic–Cold Siberia (WACS) pattern, which represents an anti‐correlation of surface temperature between the Barents–Kara Seas and central Asia. We confirm a robust link between UB and the WACS pattern on daily to subseasonal time‐scales. UB controls the pace of the WACS pattern; warming over the Barents–Kara Seas and cooling over central Asia peak 3–5 days...
