Using 19 climate models, a team of researchers led by Professor Minghua Zhang of the School of Marine and Atmospheric Sciences at Stony Brook University, discovered persistent dry and warm biases of simulated climate over the region of the Southern Great Plain in the central U.S. that was caused by poor modeling of atmospheric convective systems — the vertical transport of heat and moisture in the atmosphere.

One big reason the sea level dropped for so long: Only 6 % of the rainfall in Australia runs directly back to the sea, and the rest runs inland to lowlands (image depicts a normally dry area in eastern Australia flooded by rains in late November 2011) where it either soaks into the ground or evaporates back into the atmosphere — a process that returns moisture to the sea far more slowly than the rivers draining other continents do.

Collectively, these data show general increasing trends in both plant growth and evaporation with recent climate change mainly driven by vegetation greening and rising atmosphere moisture deficits.

By analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmospherBy analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmospherby carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmosphere.

The global warming that we have experienced so far has increased the atmosphere's moisture storage capacity by about seven per cent.

Warming oceans produced a third positive feedback cycle by pumping more moisture into the atmosphere.

However, the surface warming caused by human - produced increases in carbon dioxide, methane, and other greenhouse gases leads to a large increase in water vapor, since a warmer atmosphere holds more moisture.

A NOAA website on atmospheric rivers contains this fascinating statistic that illustrates just how much moisture can be transported by winds in the mid-to-upper atmosphere: «A strong atmospheric river transports an amount of water vapor roughly equivalent to 7.5 - 15 times the average flow of liquid water at the mouth of the Mississippi River.»

According to my old text book «A Short Course in Cloud Physics» by Rogers and Yau (1989, p. 95 in Third edition): «Condensation nuclei of some sort are always present in the atmosphere in ample numbers: clouds form whenever there are vertical air motions and sufficient moisture».

Heavier deluges are expected on a warmer planet; each temperature rise of 1 degree Celsius increases the amount of moisture the atmosphere can hold by about 7 percent.

Duration could vary: a more intense storm may peter out more quickly by having used up the available energy in the immediate vicinity (from convergence in the atmosphere as air spirals in, to surface moisture from evaporation in the strong winds) unless it moves into a new environment.

Thus, when temperatures warm, the vegetation can work from a huge store of moisture and thus add a large quantity of local moisture into the atmosphere via transpiration, in addition to what is transported here from the Gulf of Mexico by prevailing southerly winds.»

For every degree C rise in temperature the atmosphere increases its moisture content by 7 % stemming from added oceanic evaporation.

«We think the recent snowy winters could be caused by the retreating Arctic ice altering atmospheric circulation patterns by weakening westerly winds, increasing the amplitude of the jet stream and increasing the amount of moisture in the atmosphere,»

The moisture in the atmosphere, which has been widely observed to be increasing in association with increased SSTs, then gets carried around by atmospheric winds to where storms are favored.

At the very tail end of the event, colder air aloft will move in, destabilizing the atmosphere over interior NorCal and perhaps resulting in a line of two of extremely heavy convective downpours enhanced by the existing subtropical moisture (not unlike what happened during the last event in the Sierra Nevada foothills).

Some moisture, however, is added to urban atmospheres by the many combustion sources.

Trenberth notes that global warming has already increased the average amount of water vapor in the atmosphere by about 4 %, «extra moisture flowing into the storms that produced the heavy rains and likely contributed to the strength of the storms through added energy.»

He modified it in 1948 by including a moisture index that relates the amount of moisture a plant needs to the amount available, known as the Potential Evapotranspiration (PE)(evapotranspiration is the combined moisture loss from the surface either directly, due to evaporation, or indirectly transpired through the plant to the atmosphere).

For one thing turbulence instantly screws it up in the real world, moisture content screws it up, lateral transport screws it up, topology screws it up, the non-uniform temperature of the ground screws it up — the real atmosphere is constantly being kicked around between nearly isothermal and nearly DALR on any vertical column, with the actual measured thermal lapse rate rarely deviating by more than 10 - 20 % from isothermal on an actual vertical sounding of the atmosphere.

However, the surface warming caused by human - produced increases in carbon dioxide, methane, and other greenhouse gases leads to a large increase in water vapor, since a warmer atmosphere holds more moisture.

Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration.

These areas of open water influence: (1) the land by allowing more ocean waves and more coastal erosion, (2) Greenland outlet glaciers by exposing the glacier fronts to warmer ocean waters, and (3) the atmosphere by providing a source of heat and moisture during autumn.

The observations showed that when the usual shallow cumulus clouds give way to the MJO's towering cumulonimbus storms, radiant heat trapped by clouds and moisture gradually warms a deeper column of the lower atmosphere while the tops of the storms radiate heat into space, cooling the upper troposphere.

On January 3 and 4, the first of two back - to - back atmospheric river storms (wide paths of moisture in the atmosphere composed of condensed water vapor), brought heavy rain and mountain snow to central California, ahead of an even more intense round of heavy precipitation brought by a powerful, long - duration atmospheric river storm pulling warm and moist air to California from the subtropical and equatorial region southeast of Hawaii.

The climate during glacial periods is quite different and the moisture could be brought from lower latitudes by the atmosphere.

The pioneer was W.H. Dines, who gave the first explicit model including infrared radiation upward and downward from the atmosphere itself, and energy moved up from the Earth's surface into the atmosphere in the form of heat carried by moisture, Dines (1917); Hunt et al. (1986) gives a review.

Koster et al. (2004, 2006) and Guo et al. (2006) report on a new model intercomparison activity, the Global Land Atmosphere Coupling Experiment (GLACE), which compares among climate models differences in precipitation variability caused by interaction with soil moisture.

These anomalies are then transported by major ocean currents to locations where the stored energy is released into the atmosphere, altering atmospheric pressure and moisture patterns that can ultimately affect regional precipitation.

Planting trees in green areas help to limit the UHI effect, by providing shade, deflecting the sun's radiation and releasing moisture back into the atmosphere.

This difference reflects the respective changes in the rate of temperature decrease with altitude (or lapse rate), which is in turn influenced by the amount of moisture in the atmosphere.

This is caused by the increased moisture capacity of the atmosphere with increased temperature, as well as warmer oceans, seas, and rivers, which leads to increased evaporation rates.

He told Climate News Network: «That really affects how easily we cool off, because we lose heat by sweating − and the more moisture in the atmosphere, the less efficient that process becomes.»

The calculations by Kuang 2010 in which a dynamic model of radiative - convective equilibrium is perturbed systematically with different heat (and moisture) sources suggests that this is the path of least resistance for a convecting atmosphere, but that there are other possibilities as well — I need to understand this paper better.
