Lightning, Calais - Dunkerque, France, July 2nd & 3rd 2009


Page 2: A whole night of heat storms with lightning



Rising and dissipating cumulus congestus clouds at home. They would not develop any further than this until the morning hours the day after

Driving along the highway to the west near the Belgian-French border where some small heat storms developed (with tops till 14km / 45,000 feet) though

These small heat storms were very short lived and dissipated again

With no convection in sight, we went to eat some fries (and reloading the laptops battery). When we came out, new towers were developing again. A very good sign since the sun was setting, and simple diurnal heating could no longer be the only cause.

Good looking pop-corn convection

Found a better location to observe the new convective towers

More convective towers developing further west. These were not going to dissipate...
