摘要:
利用热带气旋和全球闪电定位网资料对比分析了1305号热带风暴"贝碧嘉"和1409号超强台风"威马逊"的闪电时空分布特征。结果表明:贝碧嘉和威马逊的每小时闪电频次都在振荡变化,整体上,威马逊闪电频次波形振幅变化不大,而贝碧嘉有明显的减小趋势;贝碧嘉闪电在300km以外的外雨带最频繁,威马逊闪电在160km以外的内雨带和外雨带最多;闪电都主要发生在贝碧嘉和威马逊的西半部分;贝碧嘉闪电活动主要分布在气旋移动方向的左后方,威马逊闪电活动最多发生在移动方向的右前方和左前方。
Abstract:
Based on the lightning flash data from the World Wide Lightning Location Network and storm intensity and track data from Shanghai Typhoon Institute, the temporal and spatial characteristics of lightning activity of tropical storm Bebinca (2013) and super typhoon Rammasun (2014) were comparatively analyzed. The result show that both of the waveforms of temporal evolution of lightning rates in Bebinca and Rammasun are vacillation change. Overall, waveform amplitude change of lightning rates in Rammasun is not large, but decreasing trend of lightning rates in Bebinca is obvious. In radial, lightning activity of Bebinca occurred mainly in the rain band more than 300km away, lightning activity of Rammasun occurred mainly in the rain band more than 160km away. Meanwhile, lightning concentrated in the western half part of Bebinca and Rammasun, which is also the right front and left front of the moving Rammasun, and left rear of the moving Bebinca.
