| 摘 要： | 从数值预报资料入手,结合风廓线雷达、多普勒雷达及自动气象观测资料对2008年9月14日飞船主着陆场区一次雹暴过程进行分析。结果表明:这次雹暴过程中气象要素变化剧烈;侵入蒙古低压的冷锋带动中尺度辐合线移近场区时触发强对流迅猛发展;雹暴前期垂直风切变显著增大;深厚的对流不稳定层结、强烈的正涡度平流和垂直上升运动等是雹暴的主要成因;雹暴前期TBB值迅速降低,雷达RHI回波图上,在无回波穹窿区上部为雹源区;冰雹落在θse舌轴的北侧和高空锋区的南侧。 |

| Abstract: | By means of the numerical prediction data,wind profile and Doppler radar data,and automatic meteorological observation data from the main landing site,an analysis is made of a hail storms process on 14 September 2008.The results indicate that during the hailstorm,the essential meteorological factors changed fiercely,and the cold front of the invasive Mongolia low along with a mesoscale convergence line,moving close to the main landing site,triggered the rapid development of strong convection; in the earlier... |
