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>(a) The blocking area averaged planetary-scale 500 hPa height (m) versus time (days), for a stationary box (40°N to 80°N and 160°E to 260°E), in the midlatitude northern hemispheric flow. The dashed dotted horizontal line defines the monthly mean value for the planetary-scale height. The left vertical line marks the beginning, whereas the right vertical line marks the end of the selected blocking event; (b) same as Figure <a href="../fig4/">4</a>a except for the synoptic-scale height.</table>
