During the dry season,
with no fog layer to reflect sunlight, the smaller cloud cover allows plants to receive much higher radiation,
increasing evaporation and photosynthesis rates, another process missed by the GCMs.
The apparent rise in evapotranspiration — the process by which water is transferred from the land to the atmosphere by
evaporation from plants and soil — is
increasing potential drought risk
with rising temperature trends, especially during periodic drought cycles that have been linked
with strong El Nino events.
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.
The clearest impact of warming on drought is when higher temperatures cause more
evaporation and
increase water demand, as has happened
with this drought.
They found that
evaporation of water from the soil surface significantly decreased
with increasing aggregate mulch thickness.
However, in many of the same places, actual evapotranspiration inferred from surface water balance exhibits an
increase in association
with enhanced soil wetness from
increased precipitation, as the actual evapotranspiration becomes closer to the potential
evaporation measured by the pans.
Alarmists have drawn some support for
increased claims of tropical storminess from a casual claim by Sir John Houghton of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) that a warmer world would have more
evaporation,
with latent heat providing more energy for disturbances.
Although records are sparse, pan
evaporation is estimated to have decreased in many places due to decreases in surface radiation associated
with increases in clouds, changes in cloud properties and / or
increases in air pollution (aerosols), especially from 1970 to 1990.

Lake Turkana is a closed basin lake, and
with climate change, you already have
increased evaporation, which leads to alteration of the chemical composition of the lake — and alters the ecosystem, and the fish and all the animals living in it.
One other factor here is
increased evaporation at the equator which has
increased the salanity of tropical waters along
with increased percipitation at the poles seems to be making the thermohaline system move faster which in turn carries move heat to the poles and hence
increases polar ice melting and hence possibly a greater chance of slowdown of the thermohaline system.
The higher temperatures associated
with climate change near the surface are resulting in
increased evaporation, leading to more water vapor in the stratosphere which chemically reacting
with the ozone — resulting in ozone depletion.
As surface water
increases with melting ice will more
evaporation create more overcast, and stop the warning, and even send us shivering for the igloo.
That article pointed out that warmer weather makes a drought worse than it would have been
with cooler weather because it
increases evaporation.
Consistent
with how I was reading things, pleasantly — barring some cautious hedging I'd made, based on the possibility that salinity could reflect mass changes, either when fresh water was added to the ocean via glacial melt or impoundment decreases (ocean mass
increase) or via
increased evaporation rates (ocean mass decrease).
There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located
with increased evaporation and
increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.
However,
with me at least, a bit part of the deal is the
increased acidity reducing fish harvests, water shortages, droughts severely reducing crops (sure — more rain, but more over the ocean, less on land — and
with greater
evaporation before the water trickles to a dry stream bed),
increased heat reducing rice production and other heat sensative crops, the heat waves, etc..
I haven't read the papers and don't know what is happening
with salinity in the rest of the Atlantic, but looking at your map it occurred to me that if there was
increased freshwater in the Northern Ocean due to ice melting and
increase salinity in the tropical Atlantic due to
increased evaporation, couldn't a mixing effect at the southern edge of the Northern ocean as tropical water is circulated north show similar results?
This forest, too, is not adapted to fire, and when
increased heat causes rapid
evaporation - even
with similar precipitation - our greatest biological treasure and one of our largest carbon sinks will go up in a giant ball of flame.
Then again,
with a big expanse of exposed arctic ocean, you would expect
evaporation to
increase, so rainfall might be expected to
increase north of the confluence of the Polar and Ferrel cells.
The idea of an
evaporation thermostat was proposed in the 1970's by Newell, and was based on erroneous reasoning confusing correlation
with causation; when one does the physics, one finds that
evaporation increases the air - sea coupling, but can't prevent a warming if the atmosphere itself warms.
Annual average
evaporation (Figure 10.12)
increases over much of the ocean,
with spatial variations tending to relate to those in the surface warming (Figure 10.8).
The excessive
evaporation increase under warming
with prescribed SST leads to an over-moistened MBL and distorted low - cloud responses to warming (e.g. Webb and Lock 2013).
However, there is also the expansion of the Hadley Cells where water vapor from tropical ocean
evaporation rises, water in the form of rain falls out as the air cools
with increased altitude, then dry air descends at poleward edge of the cells in the dry subtropics.
In a 1998 report, scientists from NOAA explained that higher global temperatures might be
increasing evaporation from land and adding moisture to the air, thus intensifying the storms and floods associated
with El Niño.

With warming planet, there is
increased evaporation and more water present in atmosphere.
Where did I write that, outside of the tropical Pacific, a rise in SST anomalies associated
with an El nino event was caused by
with an
increase in
evaporation?
I conclude that the observed global aridity changes up to 2010 are consistent
with model predictions, which suggest severe and widespread droughts in the next 30 — 90 years over many land areas resulting from either decreased precipitation and / or
increased evaporation.
Temperatures are continuing to rise
with consequent
increases in
evaporation and atmospheric humidity and reductions in snow amount and snow season length in many regions.
He had already been warned on this thread that when I had earlier answered a legitimate question from a commenter far more polite and sensible than he, I had replied
with a straightforward account of how Professor Lindzen, in a talk that he had given under my chairmanship at the Houses of Parliament, had calculated that if the
increase in
evaporation from the Earth's surface
with warming was thrice that which the models predicted then climate sensitivity was one - third of that which the models predicted.
You claim such a justification from the coincidence that the 1 % to 3 %
increase in
evaporation seen across the models yields a range of climate sensitivities more or less in line
with the IPCC range.
While the years
with warm and wet weather extremes have also become more common in the state,
increased temperatures accompanying the precipitation tend to lead to quicker
evaporation, Diffenbaugh said.
This study seems to conflict
with Kunkel et al. (1996), which found that
evaporation from corn agriculture significantly
increased the «sensible heat» of Midwest summers, including the deadly 1995 Chicago heat wave.
As a checksum, we can plug the modeled 3 % - per - Kelvin (2) and 1 % - per - Kelvin (3)
increases in
evaporation with warming, as well as the observed 5.7 %
increase (4), into (1) to determine the warming ∆ T (2x) at a doubling of CO2 concentration:
A higher atmospheric temperature reduces net IR losses and energy accumulates until losses are again balanced
with evaporation, conduction,
increased IR up or all three.
Hence less than 0.8 W / m ² radiated from the surface do no longer reach the cosmos [26] and are carried away by the
evaporation associated
with a minuscule temperature
increase of the surface: for
evaporation at +6 W / m ² / °C, the required temperature
increase would be 0.13 °C spread over the 200 years it would take to double the CO2 content of the air at the rate of +2 ppm / year.
«
With global temperatures warmer now than they were at the beginning of the last century, that means our temperatures are warmer too, which
increases the rate of
evaporation and
increases the demands on water,
increases the stress on the water supply, and also leaves us more susceptible to breaking the high - temperature record, which we've been doing lately,» Nielsen - Gammon said.
11
increased evaporation leaves salt behind, which
increases the density dense water sinks and is replaced
with less dense water Example: Mediterranean
This rather trivial correlation is to be expected in light of
evaporation increasing exponentially
with temperature, leading eventually to greater cloudiness.
The rate of
evaporation also
increases with temperature, also a cooling effect.
Moreover, significant trends in sensible heat and
evaporation rates are evident in satellite - derived datasets, especially in the Barents - Kara Sea region in the fall due to
increases in the air - sea temperature and humidity gradients, collocated
with reductions in sea ice.
With evaporation being the more powerful effect the rate of energy flow to the air above is likely to
increase rather than decrease and the 1 mm deep layer descend and / or intensify despite a warming of the topmost few microns.
«The logic is clear: when temperatures
increase there is more
evaporation and the atmosphere has a greater capacity to absorb water vapour,
with the result that its energy content is higher.
Sure you're adding energy, but you simply can not make the
increase in energy carried away by
evaporation greater than the energy you added
with the DLR.
The
increased evaporation must always use up ALL the DLR
with nothing left over to add to the system.
I've taken on board the point about NET cooling and dealt
with it above but your problem is that somehow you need to get to NET warming DESPITE
increased evaporation.
Warming of the skin layer, but not the water below, will slow as
evaporation and radiation
increase with rising temperature.
The skin layer does get warmer
with more DLR but at the same time the interacting layer above it gets cooler because of the deficit created by
increased evaporation taking place in that interacting layer.
