In May 2007, in preparation for the support to the international Convective and Orographically-induced Precipitation Study (COPS), a 19-day series of rapid scans was performed with the Meteosat-8 satellite over the period 11-29 May 2007. The images and animations below show the situation on 25 May 2007 when severe thunderstorms developed along a low-level airmass boundary in France and Germany. In the afternoon Paris and Berlin were hit more or less simultaneously by major thunderstorms with heavy precipitation and strong wind gusts. As one can see in the animations, the high repeat cycle leads to very smooth movements/transitions of the cloud systems (i.e. no jumps as regards position and movement of clouds) when compared to the 15-minutes repeat cycle (see Animation, 08:59-16:59 UTC, MPG, 3822 KB). Moreover, the high repeat cycle is essential for the early detection of rapidly developing thunderstorms. Another example of this can be seen over Northern Spain (see Animation, 08:59-14:04 UTC, MPG, 3249 KB).
