(a) The 500 hPa mean daily height. The cross indicates the center of blocking at the onset. The blocking domain boundary is marked around the center by thick solid black line. The continuous curves represent height contours at 50 m interval, for 05 August 2004. Note the meridional (split)-flow character of the block; (b) for 13 August 2004; (c) for 27 August 2004.
