Abstract
The weather situation, physical conditions, satellites images and so on of a heavy precipitation process happened from July 20 to 21, 2010 in Northeast China were analyzed, the occurrence characteristics and causes of this rainstorm weather were studied. Results showed that, the interaction of northward-moving subtropical high with the northern cold vortex system produced different precipitation in East and West Heilongjiang Province. Under the influence of unstable cold vortex system, short-time heavy rainfall often happed in West Heilongjiang Province; East Heilongjiang was on the external vapor channel of subtropical high, the well coordination of cold and warm air and good moisture convergence conditions led to heavy rainfall in South Harbin. As seen in satellite images, west cold vortex center was dominated by short-time convec-tive precipitation, while the east was dominated by consecutive precipitation.关键词
