Sentences with phrase «concentration of water vapor»

Warm air can sustain a higher concentration of water vapor than cooler air without becoming saturated.

However, because atmospheric concentrations of water vapor tend to be at most only a few percent of the amount of air (and usually much lower), they are both often expressed in units of grams of water vapor per kilogram of (moist or dry) air.

As this sinking air mass weighs on the marine layer, the latter compresses into a thin layer with a relatively high concentration of water vapor.

It would provide important insight into how much SRM would reduce radiative heating, the concentration of water vapor in the stratosphere, and the processes that determine water vapor transport — which affects the concentration of ozone.

Above the treetops, he checks a cluster of instruments that analyze the lush canopy as a collection of numbers: the amount of carbon being inhaled from the atmosphere, the concentration of water vapor in the air and the precise mix of hues the leaves exhibit.

Outside of an increase in temperature, I don't see any particular reason to expect hydrogen - based fuels to do anything to increase the concentration of water vapor in the air.

Water vapor will move by vapor diffusion from a high concentration of water vapor to a lower concentration of water vapor.

However the concentration of water vapor varies with the temperature and is not directly affected by human activities.

The concentration of water vapor in the atmosphere reflects the number of molecules of water compared with the total number of air molecules (mainly nitrogen and oxygen).

A recent analysis argues that the concentration of water vapor in the stratosphere decreases by about 10 % after 2000 and this slows the rate of temperature increase by about 25 % relative to the increase that would have occurred due to CO2 and other greenhouse gases (6).

Consequently, as air warms, for whatever reason, more evaporation may take place and the concentration of water vapor may increase.

Where water vapor is important is as a feedback effect... whereby the warming of the atmosphere due to increased CO2 causes the «equilibrium» concentration of water vapor to increase and this then enhances the warming because of water vapor's absorption of infrared radiation.

Increases in evaporation and concentration of water vapor in the atmosphere are the consequence of, not the trigger for, global warming.

This and other basic principles indicate that warming associated with increased concentrations of the other greenhouse gases also will increase the concentration of water vapor (assuming that the relative humidity remains approximately constant; modeling and observational studies find that this is indeed so).
