| 摘 要： | 用无狭缝摄谱仪获得了青海高原地区云对地闪电回击过程的光谱,在谱线辨认和光谱特征分析的基础上,根据光谱线相对强度和跃迁参数值,用多谱线法,对回击通道不同高度处的温度进行了定量分析。结果表明,通道温度与闪电放电的强度密切相关,一般情况下,闪电放电过程越强,对应的通道温度越高;对通道不同高度处的数据分析发现,同一回击的通道温度随高度的增加略呈减小趋势。 |
| 关 键 词： | 青海地区 闪电光谱 通道温度 |

| Abstract: | Slit-less spectra for first return stroke of lightning between the cloud and ground have been obtained in Qinghai Plateau.According to the relative intensities of lines and transition parameters,the temperatures for individual lightning strokes and at different heights of the same discharge channel have been calculated by using multiple-line method.The result shows that the temperatures in return stroke channel vary from stroke to stroke.In generally,the moreintensive lightning discharge,the higher is the value of channel temperature.On the other hand,for a certain return stroke channel,temperatures at different positions show signs of falling away with increasing height alone the discharge channel. |
| Keywords: | Qinghai area Lightning spectra Channel temperature |
