The researchers believe the greening is a response to
higher atmospheric carbon dioxide inducing decreases in plant stomatal conductance — the measure of the rate of passage of carbon dioxide entering, or
water vapor exiting, through the stomata of a leaf — and increases in soil
water, thus enhancing vegetation growth.
Meanwhile, dry regions in the subtropics will get even drier because of
atmospheric circulation patterns that carry
water vapor away to
higher latitudes.
They had assumed that
atmospheric water vapor had seeped into
high - latitude martian soil and frozen between soil particles, forming a half - ice, half - soil mixture.
He notes that DMF could rapidly replace ethanol, because it not only provides more energy but also has a
higher boiling point (allowing DMF to blend more easily with gasoline) and it does not react with
water (ethanol absorbs
atmospheric water vapor, which degrades its potency).
Predictive accuracies ranging from 89.4 % to as
high as 99.1 % show that trained deep learning neural networks (DNNs) can identify weather fronts, tropical cyclones, and long narrow air flows that transport
water vapor from the tropics called
atmospheric rivers.
Their argument is that tropical Cumulonimbus (thunderstorm) clouds procuce less
high - level cirrus - cloud outflow when sea surface temperatures (SST's) are warmer and
atmospheric water vapor is
higher.
(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.
The convective heat / mass transfer due to
water dwarfs any radiative forcing; besides — just on optical depth alone, any re-radiated LWIR from
atmospheric CO2 would be IMMEDIATELY absorbed by the much
higher concentration of
water vapor in the atmosphere (aka clouds!)
«What our study shows is that observed
water vapor concentrations are
high enough and temperatures are low enough over the U.S. in summertime to initiate the chemistry that is known to lead to ozone losses,» said Harvard
atmospheric scientist David Wilmouth, one of the paper's co-authors, in an email.
States that other feedbacks likely to emerge are those in which key processes include surface fluxes of trace gases, changes in the distribution of vegetation, changes in surface soil moisture, changes in
atmospheric water vapor arising from
higher temperatures and greater areas of open ocean, impacts of Arctic freshwater fluxes on the meridional overturning circulation of the ocean, and changes in Arctic clouds resulting from changes in
water vapor content
[26] Historically, the most intense storms and precipitation events in California have been tied to wintertime
atmospheric rivers that fed on
high levels of
water vapor in the air.
Micro bubbles found in deep polar ice cores of the ancient atmosphere (1 - 200,000 years ago) showed a
higher atmospheric density than now, perhaps 2 atmospheres, also
higher water vapor and CO2.
I know the data say that 99 % of all the
atmospheric Water Vapor (WV) is to be found in the Troposphere, so yes it is very likely to be some in the «tropospause» and even maybe as
high up as in the Stratosphere.
One of the most well - known effects of global warming is an intensification of the
water cycle, with
higher air temperatures leading to increased evaporation from the seas and soils, and more
atmospheric water vapor contributing to more frequent heavy precipitation events.
