We know that there need to be certain conditions of temperature, relative humidity, and wind speeds at different altitudes.

«The relative humidity was 80 percent there,» Masters says.

And clouds form when 1) the relative humidity reaches 100 % and 2) there are sufficient nucleation sites.

Though there are many caves, only a small number have the best conditions for climate study, including 100 percent relative humidity, constant temperatures, no cave winds, and the actual stalagmites — free of holes and decay — forming in the cave.

There, we find frozen, in aesthetically serene images, the historical and sociological riots trapped in silent surroundings, embraced by relative humidity and temperature.

Obviously, in an actual cloud, the relative humidity is close to 100 %, but at a grid box scale of 100's of km, the mean humidity — even if there are quite a few clouds — will be substantially less.

The water vapor feedback (a generally positive feedback)-- there is an roughly exponential increase in saturation water vapor pressure with increasing temperature, and the relative humidity (at a given vertical level) overall tends not to change a lot globally, though there will be different regional trends associated with shifting precipitation patterns.

There is a recent study tending to demonstrate that the average relative humidity is indeed close to constant.

There is a FAQ about this, which describes how to calculate the 2m specific and relative humidity: http://www.ecmwf.int/en/does-era-40-dataset-contain-near-surface-humidity-data

With wNA forest loss, there are significant declines in both precipitation and temperature during the early growing season, however it is the change in the relative humidity that dominates the observed increase in VPD.

There is a near infinite supply of greenhouse gases available to the atmosphere in the form of water vapor from the ocean to provide the greenhouse effect, but the relative humidity in the atmosphere is much less than one.

The declining relative humidity reduces the temperature compared to the model projections so there is no hot spot.

There is no temperature dependence or vapor pressure dependence except where temperature affects relative humidity or where vapor pressure affects relative humidity.

Air in clouds and immediately next to the ocean surface is at or near 100 % relative humidity, so as temperatures increase the absolute humidity there also increases.

If you actually look at the data for the last few decades... there's evidence for rising specific humidity in the upper troposphere, but we don't have enough data about relative humidity to say either way.

Given there is much more water vapour in the lower levels of the atmosphere, the study really found that there was a decline in overall global relative humidity when global warming theory suggests it should stay more - or-less stable.

There are supposed to be subtle changes in relative humidity in different layers and latitudes depending on temperature changes but global warming theory suggests relative humidity should stay more - or-less stable.

Given there is much more water vapour in the lower levels of the atmosphere, the study really found that there was a decline in overall global relative humidity.

The study found there was a 1.5 % (percentage points) decline in relative humidity in the very lower levels of the troposphere and a 1.5 % increase in relative humidity in the upper layers of the troposphere.

I think the study just confirmed there are changes in relative humidity that we do not understand yet.

As I read for example Bony et al. 2006, Soden and Held 2006, there are in the IPCC dogma four «feedbacks»: increased atmospheric optical thickness due to increased water vapour column amount due to sustained relative humidity; cloud radiative effects; albedo effects; lapse rate effects.

m day and night 24/365 for the flat earth assumed by Trenberth & Kiehl, above which there is an apparently stationary sun), relative humidity, water vapour (H2O), windspeed, etc., plus the all - in Net anthro Forcing of GISS that I used in my last (it does not help your cause if you had actually read my results).

I know very little about tropical dynamics, but have a half - thought question related to the tropical lapse rate: Is there a simple argument for why the relative humidity over land is expected to remain fixed?

Isaac — Among unsettled issues is the change in upper tropospheric humidity with warming — specific humdity increases, but there is conflicting information as to whether this increase is sufficient to maintain a near - constant relative humidity (RH — e.g. Minschwaner and Dessler 2004 as compared with Soden et al 2005).

kuhnkat: I was too hasty, in fact at Des Moines Relative Humidity is highly significant, but negative, and it is average windspeed that there at least plays no significant role whilst also having a negative impact on mean annual temperature.
