| Abstract: | The mesoscale convective weather of Yingkou area was analysised.The results indicated that hailstone was accured in the troposphere middle and lower levels,between the most wet areas and dry lines(point front),near the most wet areas.It always accured in the shearing places of the troposphere middle and lower levels and the ground,acting in concert with the point front;It has the abvious expression at the radar products.Hailstone echo was greater than 60 dBz at the strength products.It has the mesocyclone or mesoscale convergence line at the speed products,vertical liquid water content exceeded 50 kg/m2. |
