Previous studies reported a wide range of stratospheric water vapor feedback strength from 0.02 to 0.3 Wm - 2K - 1» https://ams.confex.com/ams/21Fluid19Middle/webprogram/Paper319586.html

I wonder what would happen if the same approach was applied to other climate metrics, like sea surface temperature, water vapor feedback strength, and precipitation - evaporation changes.

Not exact matches

This clearly confuses relative humidity in the boundary layer (which determines evaporation) and specific humidity throughout the troposphere (which determines the strength of the water vapor feedback).

«By comparing the response of clouds and water vapor to ENSO forcing in nature with that in AMIP simulations by some leading climate models, an earlier evaluation of tropical cloud and water vapor feedbacks has revealed two common biases in the models: (1) an underestimate of the strength of the negative cloud albedo feedback and (2) an overestimate of the positive feedback from the greenhouse effect of water vapor.

Andrew Lacis wrote: (3) Water vapor and clouds account for about 75 % the strength of the terrestrial greenhouse effect, but are feedback effects that require sustained radiative forcing to maintain their atmospheric distribution.

(3) Water vapor and clouds account for about 75 % the strength of the terrestrial greenhouse effect, but are feedback effects that require sustained radiative forcing to maintain their atmospheric distribution.

Pekka, «What makes you claim that the strength of water vapor feedback has any influence on my argument?»

28 Estimated Strength of Water Vapor Feedback Earliest studies suggest that if the absolute humidity increases in proportion to the saturation vapor pressure (constant relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute humiVapor Feedback Earliest studies suggest that if the absolute humidity increases in proportion to the saturation vapor pressure (constant relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute hFeedback Earliest studies suggest that if the absolute humidity increases in proportion to the saturation vapor pressure (constant relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute humivapor pressure (constant relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute humivapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute hfeedback that will double the sensitivity of climate compared to an assumption of fixed absolute humidity.

Unlike Charney climate sensitivity, which is related to the strength of feedbacks involving short timescale climate processes such as those involving clouds and water vapor, Earth System sensitivity also integrates feedbacks involving long timescale changes in the cryosphere, terrestrial vegetation, and deep ocean circulation.

The basic results of this climate model analysis are that: (1) it is increase in atmospheric CO2 (and the other minor non-condensing greenhouse gases) that control the greenhouse warming of the climate system; (2) water vapor and clouds are feedback effects that magnify the strength of the greenhouse effect due to the non-condensing greenhouse gases by about a factor of three; (3) the large heat capacity of the ocean and the rate of heat transport into the ocean sets the time scale for the climate system to approach energy balance equilibrium.

There is some uncertainty in the water vapor and cloud feedback strength, but this is not a serious uncertainty since water vapor and clouds are constrained by the Clausius - Clapeyron relation, and since the SW and LW radiative effects of clouds cancel each other to a large degree.

Upper tropospheric humidity is a critical topic in assessing the strength of water vapor feedbacks — knowledge that is essential to understand just how much temperature increase can be expected from doubled CO2.

The fundamental issue is the ratio of the various radiative feedbacks (albedo + water vapor + clouds, etc) to the strength of the Planck radiative restoring response.

Water vapor is a far more powerful greenhouse gas than CO2, so its potential strength as a feedback mechanism is high.
