摘要
为发挥多普勒雷达监测和预警冰雹、雷雨大风等强对流天气的作用,对2013年8月1日河南省驻马店市泌阳县出现的冰雹雷雨大风天气过程进行分析。结果表明,冰雹的回波强度强,达≥60 d BZ,回波顶高≥12 km;回波形态特征上,冰雹常为块状对流型;"V"型缺口、有界弱回波区等都是冰雹的典型特征。为冰雹的临近预报和人工消雹提供了科学依据。
To play the role of Doppler radar products in monitoring and giving early warning of severe convection weather such as hail and thunderstorm gale, the hail and thunderstorm process occurring in Biyang County, Zhumadian City on August 1, 2013 was analyzed. The results showed that echo intensity of the hail was as strong as≥60 dBZ, echo top height ≥12 km; in terms of echo morphological character, the hail was block convection type; V-shaped gap, bounded weak echo region were typical characteristics of hail. The study pro-vides scientific basis for the forecast and mitigation of hail.
