2004年夏天在英格兰南部进行了对流风暴启动项目（CSIP）试验性实地方案。在这次实地考察期间，观察到冷池外流在生成风暴（“主风暴”）的顺风处引发对流弧的情况。在第一道弧线的下风处又出现了三道弧线。这些弧线后来都给英格兰东南部带来了大量降雨。本文所述的模拟研究结果表明，重力波，所产生的“主风暴”，可能是负责发起进一步的三个弧的对流阵雨，观察。
The Convective Storm Initiation Project (CSIP) pilot field programme took place in the summer of 2004 in southern England. During this field campaign a case of a cold‐pool outflow initiating an arc of convection downwind of the generating storm (the ‘primary storm’) was observed. Three further arcs were initiated further downwind of this first arc. These arcs all later gave significant rainfall over south‐east England. Results from the modelling studies described in this paper show that gravity waves, generated by the ‘primary storm’, may have been responsible for initiating the further three arcs of convective showers that were observed.
