【摘要】 为了发挥雷达监测和预警强对流天气的作用,制作出精细化的临近短时预报,应用2005—2006年63次冰雹云回波资料对雷达回波参数进行了分析,得到5—8月强对流天气的回波特征。阿克苏强对流回波强度强,96.8%集中在40～60dBz,其负温区厚度很厚,正负温度区的厚度比平均为1∶2.0。更多还原

【Abstract】 The weather radar an important role in monitoring and early warning for severe convective weather.It can be applied to produce the refined short-term forecasting and nowcasting.The parameter of radar echo from 63 hail cloud echoes during 2005-2006 was analyzed,and the echo characteristics of the severe convective weather in May-Aug were obtained.In Akesu,the intensity of severe convective echoes concentrated in 40～60 dBz by 96.8 percent,their negative temperature area thickness were very thick,the average ratio of the thickness for the plus and minus temperature area was 1:2.0.更多还原
