Sentences with phrase «small amounts of water vapor»

The high level of interest in scientific circles in upper tropospheric (and stratospheric) water vapor is because it is easy to demonstrate by theory and measurement that small amounts of water vapor at high altitudes have disproportionate effects.

Small amounts of water vapor is present in the air and can carry things like mold, bacteria, and allergens.

Despite the small amount of water vapor in the upper troposphere (above about 5 km) and stratosphere, recent research has shown that upper tropospheric water vapor is very important to the climate.

Not exact matches

«There likely will be little traces of the hydrocarbons in the water that is condensed to form rain, but it will likely make up less than normal pollution does,» says research meteorologist Frank Marks, director of hurricane research at NOAA's Atlantic Oceanographic and Meteorological Laboratory in Miami, Fla. «The amount of water vapor evaporated that might contain hydrocarbons related to the spill will be very, very small.»

The small amount of heat released when water vapor condenses on ice crystals in Arctic clouds, which contain both water and ice, determines the cloud's survival, according to scientists from Pacific Northwest National Laboratory and Environment Canada.

When the water vapor evaporates, this MAY generate a small amount of negative ions.

(Note that radiative forcing is not necessarily proportional to reduction in atmospheric transparency, because relatively opaque layers in the lower warmer troposphere (water vapor, and for the fractional area they occupy, low level clouds) can reduce atmospheric transparency a lot on their own while only reducing the net upward LW flux above them by a small amount; colder, higher - level clouds will have a bigger effect on the net upward LW flux above them (per fraction of areal coverage), though they will have a smaller effect on the net upward LW flux below them.

As far as water vapor in the tropics, they even say» In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.»

This changes the brightness of the atmosphere (many small droplets reflect more than a few larger droplets made from the same amount of water vapor).

The operation of the UPP fuel cell charger is fairly quiet, although not nearly as silent as a solar charger or charging from a spare battery pack, as the device does emit a small amount of noise from the internal fan, as well as a regular clicking noise (which I understand to be from the venting of water vapor during operation).
