Changes of total and low cloud fraction and the occurrence of different cloud types over Russia were assessed. The analysis was based on visual observations from more than 1600 meteorological stations. Differences between the 2001–10 and 1991–2000 year ranges were evaluated. In general, cloud fraction has tended to increase during recent years. A major increase of total cloud fraction and a decrease of the number of days without clouds are revealed in spring and autumn mostly due to an increase of the occurrence of convective and non-precipitating stratiform clouds. In contrast, the occurrence of nimbostratus clouds has tended to decrease. In general, the ratio between the occurrence of cumulonimbus and nimbostratus clouds has increased for the period 2001–10 relative to 1991–2000. Over particular regions, a decrease of total cloud fraction and an increase of the number of days without clouds are noted.
The thick clouds of Venus do not affect the temperature-vs-pressure curve of that planet:
ReplyDeleteVenus: No Greenhouse Effect
Neither do the scattered clouds of Earth affect Earth's temperature-vs-pressure curve. The hydrostatic temperature lapse rate structure prevails over all other variables. Only that structure and the intensity of incident solar radiation affect the climate. This is the fundamental truth that everyone involved in the climate debates needs to face, and accept. To the extent that does not seem clear to a student of climate, after studying my Venus/Earth comparison, is an indication of the strength of the false theory that has been taught for a generation and more, and the hold it retains upon the individual's mind, even in the face of overwhelming, definitive evidence against it. Svensmark's theory, like every other current climate theory, has been demolished by the Venus/Earth temperature comparison, properly done, by me, for the first time since the Venus data was obtained nearly 20 years ago. The world, and the world of science in particular, needs to wake up and shrug off the bad dreams of an incompetent science consensus, with new knowledge and, most importantly for one's strength of mind, new understanding of previously ignored knowledge.
Agreed that the adiabatic lapse rate and solar insolation set the temp profiles. However, albedo affects solar insolation, so not clear why you are suggesting it can be dismissed entirely.
