利用多普勒雷达、闪电定位网、TRMM(热带雨量测量任务)、MTSAT(多功能运输卫星)影像、NCEP(国家环境预报中心)再分析和无线电探空仪等多种数据,对中国东部地区的三场夏季雷暴进行了详细分析。三个风暴中有两个会产生精灵,另一个不会产生精灵。两场产生精灵的风暴发生在2007年8月1日至2日和7月27日至28日,分别产生了16个和1个精灵。不产生精灵的风暴发生于 2007 年 7 月 29 日至 30 日。该研究的主要目标是尝试使用多个数据集找出产生精灵的风暴和不产生精灵的风暴之间可能存在的差异。结果表明,与其他风暴相比,8月1-2日风暴对流最强,产生的精灵数量最多。 8月1-2日风暴对流区降水冰、云冰和云水含量均大于其他两次风暴,但弱对流区则相反。沿着母 CG(云对地闪电)位置的风暴微物理特性没有显示出与精灵相关的特殊特征。 8 月 1 日至 2 日风暴中的闪光速率演变提供了额外的证据,即主要精灵活动与负 CG 闪光速率的快速下降同时发生。然而,7月27日至28日的精灵风暴中CG闪光速率的演化曲线不稳定,与8月1日至2日的风暴有显着不同。产生精灵的风暴中的平均正重心峰值电流大于不产生精灵的风暴中的平均正重心峰值电流。
Three summer thunderstorms in the eastern region of China were analyzed in detail using multiple data, including Doppler radar, lightning location network, TRMM (Tropical Rainfall Measuring Mission), MTSAT (Multi-Function Transport Satellite) images, NCEP (National Centers for Environmental Prediction) Reanalysis, and radiosonde. Two of the three storms were sprite-producing and the other was non-spriteproducing. The two sprite-producing storms occurred on 1–2 August and 27–28 July 2007, producing 16 and one sprite, respectively. The non-sprite-producing storm occurred on 29–30 July 2007. The major objective of the study was to try to find possible differences between sprite-producing and non-sprite producing storms using the multiple datasets. The results showed that the convection in the 1–2 August storm was the strongest compared with the other storms, and it produced the largest number of sprites. Precipitation ice, cloud ice and cloud water content in the convective regions in the 1–2 August storm were larger than in the other two storms, but the opposite was true in the weak convective regions. The storm microphysical properties along lines through parent CG (cloud-to-ground lightning) locations showed no special characteristics related to sprites. The flash rate evolution in the 1–2 August storm provided additional confirmation that major sprite activity coincides with a rapid decrease in the negative CG flash rate. However, the evolution curve of the CG flash rate was erratic in the sprite-producing storm on 27–28 July, which was significantly different from that in the 1–2 August storm. The average positive CG peak current in sprite-producing storms was larger than that in the non-sprite-producing one.
