Abstract:

利用热带测雨计划任务卫星(TRMM)的测雨雷达(PR)、闪电成像仪(LIS)和微波辐射计(TMI)资料,研究了2005年5月6日发生在我国华南的一次强飑线过程的闪电活动及其与降水结构之间的关系。结果表明,该飑线系统中对流降水面积仅为层云的一半,但是总降水率却远大于层云的总降水率。绝大多数闪电发生在对流区,有少数闪电出现在层云区域。在6km高度上,闪电发生附近的最大雷达反射率因子主要集中在35~50dBZ区间,峰值频数在40~45dBZ,35dBZ以下较少。研究还表明,对流单体的最大雷达反射率垂直廓线可以很好地指示单体的闪电频数和对流发展强度。对闪电与微波亮温的研究表明,大多数闪电发生在低亮温区域,特别是低于200K亮温区,而在240~260K的区域也可观测到少量闪电,这一般对应于飑线的层云区域。结合2003年4月17日黄淮地区的另一次强飑线系统的进一步研究发现,在单体尺度上,总闪电频数和冰相降水含量之间表现出非常密切而稳定的关系,相关系数达0.92。总闪电频数和冰相降水含量之间的稳定关系在中尺度数值模式中闪电资料的同化和飑线系统的闪电参数化研究中均有较大的应用潜力。
