Cool air offshore was very nearly at the saturation point, with a temperature near 20ºC and a dew point of about 19.5ºC. The air at this temperature can only hold a certain amount of water vapor, and how much it can hold depends heavily on the temperature. If you add more water into the air, a cloud will form, but you can also get a cloud to form by cooling the air. Drop the temperature, and it can no long hold as much water vapor, so some of it will condense out and a cloud will form."

Weather experts are gathering at the World Meteorological Organisation later this month to discuss ultra-short lasers as a promising tool for weather modulation and climate studies. Launching these lasers into the atmosphere could potentially control lightning and also assist in cloud production and rainfall. Researchers have begun testing the equipment outside, by firing short pulses of laser light at the sky.
