Abstract:
By using the Vmax mesocyclone products of new generation radar of Hefe i, the occurrence time, spatial distribution and a variety of characteristic val ues were statistically analyzed. It is discovered that the Vmax meso cyclone wh ich lasts more than three volume-scannings is well corresponds to the thundersto rm and gale. By analyzing the typical processes of gale, the relationship of th e variations in the height of echo base, echo top and severely shear with the oc currence of disaster weather was derived. It is valuable to the operator to mak e a forecast of thunderstorm and gale timely and accurately.
