Sentences with phrase «over evaporation increases»

in response to the increase of atmospheric carbon dioxide, the excess of precipitation over evaporation increases, and surface salinity is reduced in high latitudes as noted in section 8.

Not exact matches

Is it the case that evaporation will increase primarily over land while precipitation will rise mostly over oceans?

Rising temperatures over land lead to increased evaporation, which renders crops more susceptible to drought.

I've trying to find what percentage of additional evaporation there is now over the world's oceans at the current increased temp of 0.7 C over the mean.

«Century of Data Shows Intensification of Water Cycle but No Increase in Storms or Floods Released: 3/15/2006 12:13:21 PM» (excerpt) A review of the findings from more than 100 peer - reviewed studies shows that although many aspects of the global water cycle have intensified, including precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods over the past Increase in Storms or Floods Released: 3/15/2006 12:13:21 PM» (excerpt) A review of the findings from more than 100 peer - reviewed studies shows that although many aspects of the global water cycle have intensified, including precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods over the past increase in the frequency or intensity of tropical storms or floods over the past century.

Further, let's agree that this will on average cause more precipitation due to increased evaporation at these higher temperatures (the best data I have seen say that the precipitation trend over the continental US — where we have the best long term records — is up 5 - 10 % over the last century).

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

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..

Now of course increased evaporation also means increased precipitation, but this tends to fall prematurely over the source of the evaporation — the oceans.

If precipitation increases over the tropical oceans, more than evaporation increases, the sea water salinity could decrease.

Alternatively, stronger winds over the mid latitudes may have increased evaporation and so lowered temperatures.

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 Fifth Assessment Report, issued by the United Nations Intergovernmental Panel on Climate Change (IPCC) in 2013, synthesized the available scientific studies and reported that increases in evaporation over arid lands are likely throughout the 21st century.

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.

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.

A stronger greenhouse effect puts a thicker «lid» over the Earth's surface but, if there is no additional sunlight (if we don't turn up the heat on the stove), extra evaporation takes place solely due to the increase in temperature.

Could an increase in greenhouse gases actually have a cooling effect over water by speeding up the rate of evaporation from the oceans thereby extracting energy faster from the oceans, speeding up the hydrological cycle and pushing energy faster to space?

The increased evaporation must always use up ALL the DLR with nothing left over to add to the system.

A consequence of increased heating from the human - induced enhanced greenhouse effect is increased evaporation, provided that adequate surface moisture is available (as it always is over the oceans and other wet surfaces).

This corresponds to a 2.4 cm.yr - 1 increase in evaporation rate since 1800, with 1.7 cm.yr - 1 of this increase occurring over the last 50 years.

Warmer oceans over earth increase evaporation and therefore cloud cover.

This is believable as higher temps would mean more arable land, more evaporation would mean more rainfall and we have seen over the last 50 years as CO2 has climbed that total biotic life on the planet has increased some 30 - 50 % according to NASA satellites measurements.

Whereas stronger evaporation over oceans and the tropics with rising temperature increase rainfall in the tropics and subtopics, the opposite effects occur in the dry lower - mid latitudes.

Evaporation rates are increasing over the oceans, but it's thought to be mostly due to greater windiness.

Huntington is the author of a recent review of more than 100 peer - reviewed studies showing that although many aspects of the global water cycle — including precipitation, evaporation and sea surface temperatures — have increased or risen, the trend can not be consistently correlated with increases in the frequency or intensity of storms or floods over the past century.

According to Isaac Held, climate models predict that the relative humidity over oceans will have to rise about 1 % (a 5 % increase in 1 — RH) to suppress surface evaporation which would otherwise rise at 7 % / degC and create a surface energy imbalance (because DLR increases with warming nearly as fast as OLR).

Secondly, the added warmth also increased evaporation over those waters, putting additional moisture in the air.

This is partially compensated by more evaporation and conduction / convection from the surface to remove the added energy, so that net energy balance is maintained over long times, but at an increased average surface and near surface temperature.
