Scale Analysis of Blocking Events from 2002 to 2004: A Case Study of an Unusually Persistent Blocking Event Leading to a Heat Wave in the Gulf of Alaska during August 2004

Table 1

Assessment of the blocking domain size variation, for the 500 hPa monthly average planetary-scale height, during August 2004, for the selected blocking event.

D (latitude × longitude)	Monthly planetary-scale height averaged over the blocking domain D (m)
40^∘×60^∘	5773
50^∘×70^∘	5768
60^∘×80^∘	5757
70^∘×90^∘	5743
80^∘×100^∘	5728
