700 hPa Height, Relative Humidity, and Vertical Motion
Caption: +700 hPa geopotential height (solid contours every 6 dam). +700 hPa relative humidity (green contours at 10, 30, 50, 70 and 90%). +700 hPa vertical motion [shaded according to the colorbar (10-3 hPa s-1)]. Warm (cold) colors denote regions of 700 hPa ascent (descent). +Image was generated from 1.0x1.0o NCEP-GFS data (unsmoothed).
