Fig. 3
Distribution of SAT (°C, shaded), geopotential height (m, contours), and wind (m s−1, arrows) at 500 hPa, in a JJA 2002, b first HW (25 June to 10 July), c second HW (16 July to 2 August), and d third HW (7 August to 27 August). Variables in b–d are expressed as anomalies with respect to the 30-year average (1981–2010) of the corresponding period, but as the mean absolute value for wind at the 500 hPa level. The red line in a delineates the study domain by model. Negative contours are shown by dashed lines
