I have tried to discuss the process of low barometric pressure with meteorologists, where condensation has to cause a reduction in pressure because there is a 200:1 ratio of volume between water and vapor. But the formation of cloud seems so subtle, this process seems to be ignored or almost denied. Where it really comes into play is in extreme weather where condensation and precipitation can be going on at the same time, and where the extremes of barometric pressures are found in cyclonics. So clouds do more than just block and reflect and diffuse the sun and radiate broadband both to space and downward, they are very involved in weather other than clear skies. This may be so true that surface IR radiation plays a minor role where clouds exist, making any global averages almost irrelevant. |

Precipitation may be discussed as droplets finding a particle to cling to, things can get really extreme when there is a strong interface of temperature differences. The weather phenomenon called "derecho" (straight line winds moving rapidly), I was in one in 1969, and watched the radar of another a couple of years ago, the only two I am aware of in 80 years. The one in 1969 had winds where I was near Lake Erie of well over 100 miles per hour, and lasted at least 5 minutes, taking down more than half of the mature trees in Lakewood, Ohio where trees were everywhere. It may not have been apparent, but precipitation must have been driving that. |

To what extent Arrhenius meant this when he talked of carbonic acid is debatable, in fact, there is obviously a lot more physics possible with water vapor and CO2 than with the ocean and CO2, there is not too many ways CO2 can get into the ocean. |
