Abstract:
During the spring of 2013, the surface air temperature was 1℃ higher than normal and the average precipitation was 8.3% more than normal in China. However, obvious spatial and temporal inhomogeneity was observed in both temperature and precipitation with severe cold weathers persisting in Northeast China and regional drought occurring in North China. Long persistent negative phase of Arctic Oscillation (AO), active cold vortexes and more extensive than normal snow cover over the Northeast China caused the sustained low temperature in this region. And, weaker than normal Siberian high, anomalous high ridge and inadequate water vapor transport may be the primary causes for the drought in North China.
