Development of the observation network for comprehensive study on giant thunderstorm, Hector

我们利用我们独创的闪电观测网和澳大利亚气象局的气象设备，在澳大利亚达尔文进行了研究大雷暴赫克托的野外活动。成功地实现了长水平发展的闪电导流道可视化。结果表明，云地闪光中水平的长负先导沿正电荷区边界发展。当领导者到达正电荷区的末端时，他们将方向改变为向下。尝试了一种新的闪电中和电荷分布估算方法。随着赫克托的发展，正电荷的上升被注意到了。

We have conducted field campaign in Darwin, Australia to study on giant thunderstorm, Hector by means of our original combined lightning observation network with meteorological equipments operated by Bureau of Meteorology Australia. Lightning leader channels with long horizontal developments are successfully visualized. It is concluded that the horizontal long negative leaders in cloud-to-ground flashes progress along the boundary of positive charge region. When the leaders reach the end of the positive charge regions, they change their direction to downward. An innovative estimation for charge distributions neutralized by lightning flashes is tried out. Ascent of positive charge with Hector developments is noticed.
