The prospect is good enough that there was a Conference on Laser-based Weather Control in 2011 in Geneva. This year the same organizers are putting together their second international meeting: the Conference on Laser, Weather and Climate (LWC2013) at the World Meteorological Organisation (WMO), once again in Geneva.

Their website explained that "ultra-short lasers launched into the atmosphere have emerged as a promising prospective tool for weather modulation and climate studies." They point out such prospects as the old lightning control dream, laser-assisted condensation, and then add "the striking similarities between the non-linear optical propagation and natural phenomena like rogue waves or climate bifurcations."
I will not pretend to understand more than a sliver of that last phrase, but I look forward to hearing about more specific science coming out of the conference itself, on Sept. 16-18. Meetings like these are critical for an unusual field because they require such a wide array of talents - meteorologists, atmospheric physicists, electrical engineers (someone has to work the laser), and so on - who may not all be employed at the same institution. Hopes are that collaborations will ensue. Long gone are the days when two guys with a kite, key and a jar could do meaningful science.
