A Dynamic Analysis of the Role of the Planetary- and Synoptic-Scale in the Summer of 2010 Blocking Episodes over the European Part of Russia

Figure 4

Phase trajectories for the 500-hPa heights in the central part of the blocking region for July 2010 for the (a) planetary-scale, and (b) synoptic-scale, during the preblock (solid, red—X), the block lifecycle (dots, blue—o), and decay (dash, green—diamond). The trajectory begins at (S) and ends with (E), and the block onset is marked with (O) and termination with (T). The dates are labeled as month/day.
