Figure 1 a The terrain around Northeast China shaded, units: m and the track of the Northeast China cold vortex NCCV, where circles denote the developing stage, rectangles denote the mature stage, and the triangles denote the decaying stage. Panels b-e show the geopotential height at 500 hPa shading and contours; units: gpm, where the white dashed circles stand for the mean effective radius during the mature stage: b 0000 UTC 3 July; c 0600 UTC 3 July; d 1200 UTC 3 July; e 1800 UTC 3 July 2013.
