Figure 4 Composites of a stationary, b eastward-migrating, c northeastward-migrating, and d southeastward-migrating SWVs in the warm season at 700 hPa. Solid lines represent the geopotential height units: gpm, and vectors the wind velocity units: m s -1 . Areas with #cod#x003c3; BI higher than 1#cod#x000d7;10 -7 s are shown as dashed lines. The contour interval of #cod#x003c3; BI is 10 -7 . The speed of the wind in the shaded area is #cod#x02265; 10 m s -1 . The asterisks represent the mean locations of the SWVs.
