Abstract:
Based on the conventional observation data,Doppler radar products and observations of automatic meteorological station,the paper analyzed a heavy hailstorm weather occurred in the south edge of Zhunger Basin on May 2,2010 from weather situation,cloud images change,evolution of physical quantity field and radar echo.The results showed that the hail weather occurred under the weather condition of unstable convective stratification,dry and cold at the middle or upper layer,but humid at the low layer;abundant vapor condition,a esoscale convergent shear on the ground,the suited height of the 0℃layer and-20℃layer,strong vertical wind shear were all favorable to this weather process.The Doppler radar can properly monitor the developing processe of the hailstone weather.The appearance of>50 dBZ echo section and cove configuration,convergence region and adverse wind region,increase of VIL value(Vertical Integration of Liquid water)and STI(storm track information),these all have indication to occurrence of hail weather.
Key words: hailstorm, environment field, radar product
摘要:
利用常规气象探测资料和多普勒天气雷达产品,结合石河子地区和兵团农六师的高密度自动站网资料,对2010年5月2日在准葛尔盆地南缘发生的一强冰雹天气过程,从天气形势、云图、物理量场和雷达回波演变特征等几个方面进行了综合分析。结果表明:这次冰雹天气出现在对流不稳定层结条件下,中高层干冷、低层暖湿,水汽条件充沛,0℃层和-20℃层的高度适宜,同时具有强的垂直风切变。多普勒雷达能很好地监测冰雹天气的发生发展演变过程,>50 dBZ强回波区和穹窿结构的出现,中气旋和逆风区的出现,垂直累积液态含水量(VIL)增加以及风暴跟踪信息(STI)预警等都对冰雹天气的出现具有指示意义,对今后的防雹减灾工作有较好的应用价值。
