The conditions of 30 blocking events were examined at the time of onset over the 1993/1994–1996/1997 cold season (November to March). The antecedent synoptic-scale eddies in 83.3% of the total events are shown to induce a large-scale low/high eddy forcing pattern upstream of the incipient block, and the mean basic westerly flow is weak, 76.7% of which possesses cyclonic shear. It appears that both the antecedent synoptic-scale eddies that induce a low/high eddy forcing pattern and the weak… CONTINUE READING
