| 摘 要： | 以2007-2009年的雷灾调查为基础,利用保存的MICAPS资料对9次雷灾天气进行了分析.结果表明:致灾雷电均产生在大范围较深厚的低值系统环流背景下,其中7次强雷电的T-lnp图具有喇叭口、存在逆温、SI指数较小(≤-2),其他物理量如垂直上升速度与T-lnp图或SI表现基本一致.另外2次致灾雷电产生在稳定降水形势下...

| Abstract: | Based on the lightning disasters from 2007 to 2009, making use of MICAPS data, an analysis is made of nine lightning disasters occurred in the three years. The results indicate that all lightning disasters were produced under the background of a large-scale deep low system. In seven of the lightning events, there was a trumpet-shaped pattern on the T-lnp chart or inversion temperature pattern or lower SI （less than 2）, and the physical elements, as vertical ascending velocity, is consistent with the T-lnp chart or SI. The other two lightning disasters occurred under the background of severe rainfall in stable weather |
