Sentences with phrase «greater water vapor concentrations»

Should the Hadley cell, monsoons, and Walker circulation be expected to increase in strength due to greater water vapor concentrations (except where aerosol emissions throw a wrench into it)?

Not exact matches

With JWST, a few hours of integration time will be enough to detect Earth - like levels of water vapor, molecular oxygen, carbon dioxide and other generic biosignatures on planets orbiting a white dwarf; beyond that, observing the same planet for up to 1.7 days will be enough to detect the two CFCs in concentrations of 750 parts per trillion, or 10 times greater than on Earth.

1) Even though CO2 concentrations in the atmosphere has gone up by 30 % over the last 200 years or so (compared to being stable for 400 000), I have a hard time to comprehend how an increase from 0.028 % to 0.038 % of CO2 by volume can have any effect on the thermal mass of the atmosphere considering that water vapor by volume is 50x greater and has higher thermal coefficients.

Water vapor is a stronger greenhouse gas than CO2 and its concentration in the air is between 25 and 50 times greater than CO2.

First, the concentration of water vapor in the tropical lower troposphere is already so great that there is little scope for additional greenhouse - gas forcing.
