Abstract:
A mesoscale analysis is performed of the regional heavy rain in the early summer of 2006 in Shaanxi Province with the rainfall data of automatic precipitation stations, FY2C satellite TBB, DopplerRadar data, etc. The results indicate that the regional heavy rain occurred under the effect of mesoscale convergence line and mesoβ convective cloud clusters together. The mesoscale system s corresponding to the heavy rain centers can be clearly seen from the stream field after filtering. It can be seen that the severe heavy rainfall is closely connected with the strong radar reflectivity, adverse wind area, lowlevel jet, and warm advection.
