Sentences with phrase «air than water vapor»

Not exact matches

No sooner had the aircraft begun to emerge from the lower reaches of the fog — its outer edges trailing tendrils of water vapor like wisps of smoke — than the air was rent by the pounding percussions of antiaircraft fire.
Specific humidity content of the air has increased, as expected as part of the conventional water vapor feedback, but in fact relative humidity also increased between 1950 and 1990, indicating a stronger water vapor feedback than given by the conventional assumption of fixed relative humidity.
The air at the top of the troposphere is colder than the air at the ground because of a. water vapor b. expansion of gas c. light energy d. ozone
First is that warmer air can hold more water vapor, leading to torrential rains in coastal regions that last longer than usual.
Warmer air holds more water vapor than colder air, so the amount of water vapor in the lower atmosphere increases as it is warmed by the greenhouse effect.
I believe if you just use a CLOSED cell foam (much better water / vapor / air / thermal barrier than either open cell or cellulose) with almost no thermal bridging in the wall then it kind of solves lots of problems all at once...
Since water vapor is lighter than the main constituents of air, air containing water vapor is lighter and so rises above less humid air.
A parcel of air containing water vapor is lighter than air without as much.
A thunderstorm event might be best depicted as a run - away rising column of air that is becoming progressively warmer than the surrounding air as condensing water vapor yields its heat of vaporization until almost all water vapor has condensed out and then cooling at a rate of 9.8 deg C per 1000 meters, it eventually reaches a warmer layer of air and spreads out like smoke over a ceiling.
This is because water vapor is lighter than air.
This means that air flowing from the surface and converging into the Pineapple Express would have a chance to be carrying greater - than - usual amounts of low - level water vapor, thus intensifying the moisture channel.»
This is why gardeners will put water vapor in the air and water liquid on the ground around their garden on a clear cold night — it protects the local area from cooling as fast because water vapor and liquid both 1) cool much slower than dry air due to their massive heat capacity, and 2) cool even slower because they release their massive latent heat, which means that heat energy is released from them without requiring a drop in temperature — once they're in the latent heat release phase, they just keep shedding energy without dropping in temperature any further.
Adding the influence of water vapor concentration to the density profile makes the difference between the densities of the two cases a little larger, because water vapor lowers the density as H2O molecules are lighter than average for dry air.
My guess would be that the heat capacity of the air would dominate (surely the volume of air in a forest is more than 1000x the volume of the leaves), in which case the cooling effect would still be an order of magnitude greater than the buoyancy of water vapor effect (but no more than 13X).
You are probably also aware already that water vapor is as much if not more of a so called greenhouse gas than carbon dioxide is and there is a lot of evaporating ocean water on the planet not to mention clouds and high tropical humidity because hot air provides added space in the atmosphere for water vapor gas to become a major component of air.
Water vapor is a stronger greenhouse gas than CO2 and its concentration in the air is between 25 and 50 times greater than CO2.
When you see condensation on the bathroom mirror, you know the dew point of the water vapor in the air is equal to or higher than the surface temperature of the mirror.
Shifts in clouds, water vapor, and the great currents in the ocean and air, however, cause complex responses in which some regions warm more than the average while others warm less than average, or even cool.
Warm air can hold a lot more moisture (water vapor) than colder air.
Water vapor is just a trace gas, less than one half of one percent of the air in the atmosphere.
By combining these two elements, VPD plots the unstable situation created when air holds less water vapor — or has a lower humidity — than is possible at a certain temperature.
Air masses are more mobile than the ocean waters, and when they move to a cooler region, the water vapor condenses as rain or snow, leaving the heat energy in the atmossphere.
-- It seems perfectly reasonable to me that if we imagine the surface never emits that energy in the first place, - energy that is stored in the surface and just below, i.e. oceans, lakes, rivers, ground, and air, — just to mention a few, then any surface temperature change would be completely reliant on variations in Solar irradiation and advection mainly by Water Vapor (WV) but also by other GHGs that have the ability to contain more heat than the rest of the atmospheric gases.
The end result is there's virtually no heating beyond the first few micrometers and the molecules near the surface just keep picking up more and more energy as latent heat until they have enough energy to vaporize and then they leave the surface and quickly convect upwards because water vapor is lighter than air.
Dave Springer says: ``... the molecules near the surface just keep picking up more and more energy as latent heat until they have enough energy to vaporize and then they leave the surface and quickly convect upwards because water vapor is lighter than air.

Still more persuasive to scientists of the day was the fact that water vapor, which is far more abundant in the air than carbon dioxide, also intercepts infrared radiation.
Warm air holds more water vapor than cold air does, so the air is more humid than a few years ago.
(A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)
Warmer air holds more water vapor than colder air, so global warming will make the lower atmosphere wetter.
Pekka: Your description patently conflicts with the following geophysical realities: a) Water vapor is lighter than air and adds extra lift to thermally forced convection.
«Warmer air can contain more water vapor than cooler air,» according to the 2014 Climate Assessment produced by the U.S. government.
Because water vapor is lighter than dry air (mostly nitrogen and oxygen), that layer of air can move upward in the attic.
First, warm air holds more water vapor than cold air — and the rising air temperatures since the 1970s have caused the atmospheric water vapor content to rise as well.
«Humid air holds water vapor until it contacts a surface whose temperature is less than or equal to the dew point,» he says.
