Abstract

The mesoscale divergence and its change are in good coincidence with the heavy rainfall in the Meiyu front. The orders of the divergence change and the terms related to vertical velocity (ω) and divergence (D) in divergence equation are larger in the region of heavy rainfall than in the region of weak rainfall. The low—level imbalance field (U) and nonhomogeneous field (A) that are calculated using mesoscale data coincide with the region of heavy rainfall. Calculation of these field and divergence change can provide important information for the nowcast of the mesoscale weather phenomena such as heavy rainfall
