Spatiotemporal Variability and Change of the South China Spring Precipitation during 1961–2012

Figure 10

The differences of physical fields between the abundant spring precipitation years and scarce precipitation years in the South China: (a) the 500 hPa geopotential height (dagpm); (b) the 850 hPa wind (ms⁻¹); (c) the low-level convergence (10⁻³ s⁻¹); and (d) the zonally averaged (along 110°–120°E) vertical velocity in p-coordinate (10⁻³ Pa s⁻¹).
