Who has their head in the clouds?

Clouds are a huge issue because when the water vapor becomes a liquid droplet; it also goes from being a GHG and thermal insulator to a solar reflector and ground shade producer. Even the act of transition, condensation, releases heat.
Getting a grip on total precipitable water in the atmosphere and knowing what phase it is in, for how long, and where, could tell us more about global temperatures. That knowledge may improve climate model predictions.

On the flip side there may be anthropogenic sources of gasses or particles that inhibit nucleation or increase evaporation. Shortening the time atmospheric water stays liquid would be a huge GHG producer. Something like that might have a bigger impact on global climate than CO2 or methane.
An increase in daytime clouds and decrease in nighttime clouds cool areas regionally. Knowing these trends and temporal patterns would be a boon for modelers.

Has anybody looked at the impact of seeding clouds to make them rain or incidental seeding on air column temperatures. I would expect that pulling liquid water out of the air would also decrease the residence time of liquid water in the atmosphere and consequently increase insolation to the lower atmosphere, surface, and ocean.

Continuous and increasing emissions of particulates from fossil fuel combustion might be such a climate-changing source. It seems worth a look. We now have water vapor, and visual satellite sensors. What I don’t know is how long they have been tracking global data and what trends they have picked up globally and in proximity to new power plants. Does water vapor from all the cooling towers impact local or regional temperatures?

Cake and Storms

By: biff4ugo, 5:19 PM GMT on June 07, 2010

For my friend and his 5 year old's birthdays, their wife/mom made an Iron Man cake that was life sized! I helped her with the fondit skin. There was also a pig roast, cuban style that was dampened by the heat but the rain held off till after the pinanta.
We got 1.5" rain burst on Friday 5/4/10 over about 40 min. and another .25" Sunday that looked like more in a long drizzle, but the rain gage said no, only a quarter.
Lake levels across the NE are looking good still.
No oil on the East Coast of FL yet.
Hope you all had a great weekend too.
