千（阳）陇（县）地区冰雹的成因分析

ANALYSING ORIGIN OF THE HAILSTORM WEATHER IN QIANYANG AND LONGXAN

根据多年冰雹预报工作的研究成果，分析了千（阳）陇（县）地区１９６２－１９９４年的冰雹过程，归纳出千陇地区冰雹天气气候规律，及有利于冰雹产生的天气形势和物理量、雷达回波判别指标和判别方程。为准确预报该区冰雹天气提供一些依据。

On the basis of the hailstorm forecast research for many years, authors analyse the processes of the hailstorm in the Qianyang and Longxan from 1962 to 1994,and sum up the characters of the hailstome weather、 the physical quantum, the synoptic situation that is benefical to hailstorm. and indexs of the radar pulses、and the discriminant equation. It provides basis for exactly forecasting the hailstorm weather.
