Fig. (15) WRF-UEMS Run B2 (WDM6 scheme) cross-section X4 in Fig. (1b) (a) 0000 UTC, (b) 0600 UTC, and (c) 1200 UTC 27 December 2003 with snow mixing ratio (filled colors with solid black contours and black labels: 10-3 g kg-1), equivalent potential temperature (dashed green contours: oK), and vertical velocity (ω < 0: solid purple contours and labels: Pa s-1; ω > 0: dashed pink contours and labels: Pa s-1). The grey arrows with blue outlines show the direction of the vertical motion fields. The horizontal (transect: 270 km) and vertical (pressure: hPa) axes are displayed in the figures.
