Sentences with phrase «ocean evaporation rate»

Not exact matches

The winds can affect rates of evaporation, which cool an ocean in much the same way as sweating can cool the skin, affecting the amount of heat that moves between the sky and the ocean.

Warm oceans produced extensive evaporation and precipitation, which on the cold continents resulted in extreme snowfall rates that built up glaciers.

There are some various proposed mechanisms to explain this that involve the surface energy balance (e.g., less coupling between the ground temperature and lower air temperature over land because of less potential for evaporation), and also lapse rate differences over ocean and land (see Joshi et al 2008, Climate Dynamics), as well as vegetation or cloud changes.

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).

If we isolate the ocean for diagnosis, there is a rather short list of suspect forcings and feedbacks (ie changes in shortwave reaching ocean surface possibly from strong negative aerosol feedbacks, net positive rate change in loss of longwave from the ocean (which would have implications for the positive WVF), net positive heat loss through evaporation without balancing compensation (with other implications for positive WVF).

The rate of evaporation from the ocean seems to be increasing as the world warms.

Is it the long - awaited, predicted and scientifically reasonable CO2 fertilization feedback effect on the oceans» vast biomass of CO2 - consuming cyanobacteria, albeit also driven by the (literally) «shit - loads» of nitrogen compounds the human race is also pumping into the oceans — thereby shifting sea surface albedos, reducing evaporation rates and troposphere relative humidities (ringing any bells here, bros)?

If we are to get a real idea of the rate of tropical convection that drives Hadley cell dynamics and the size of the subtropical high pressure cells we need to measure the rate of evaporation from the tropical ocean.

The rate of evaporation from the ocean is increasing as the world warms.

Since latent heat transport (and surface cooling of the ocean) must increase in proportion to the rate of evaporation, perhaps Wentz et al have identified a reason why the models appear to overstate climate sensitivity: the actual latent cooling increases by about 4 watts per square meter more than the models predict for each degree rise in surface temperature.

The existence of that cooler layer is evidence that the rate of evaporation is the primary influence on variability in the rate of ocean energy loss (apart from internal ocean circulation variability which is not relevant here) and it follows that more evaporation for the same rate of conduction and radiation (from a stable temperature differential) will send that cooler layer deeper and / or intensify the temperature differential between it and the ocean bulk below.

Indeed, the faster the rate of evaporation the deeper the level of temperature discontinuity will go and / or the larger the temperature differential will be between the cooler layer and the ocean bulk below.

I have been engaged in a discussion with a young climatology professional who thought that evaporation from the ocean surface left behind a residue of surplus energy to warm the oceans by reducing the rate of energy release from the oceans and thus justifying the AGW scenario.

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?

Instead the rate of energy flow from ocean to air would be primarily governed by the rate of evaporation and not by temperature differentials.

So if one increases the rate of downwelling IR (thereby increasing the evaporation rate) then the increase in upward energy flow caused by the fall in the temperature of that 1 mm layer will be greater than the decrease in upward energy flow that will result from any reduced temperature differential between the topmost Knudsen layer and the ocean bulk arising from the application of Fourier's Law.

The oceans control the background rate of energy flow from ocean to air via The Hot Water Bottle Effect and it is the energy flow from ocean to air (supplemented to a miniscule extent by the greenhouse effect) that drives the rate of evaporation by creating varying temperature differentials between sea surface and air at the surface.

Warmer water surfaces from extra downwelling infra red can not cause warming of the ocean bulk because the rate of evaporation increases proportionately to the extra energy available and the latent heat of evaporation is then taken mostly from the water.It is then no longer available to warm the ocean bulk.

... The increase in flux is converted by the ocean surface into an insignificant change in evaporation rate.

As the world warms, the rate of evaporation from our oceans seems to be increasing, powering ever - stronger storms.

The rate of evaporation always increases in proportion to the supply of extra energy to water molecules at the surface or to molecules of air that are in contact with the water surface so that no warming of the ocean by the air can occur.

As regards a warming of the ocean skin, evaporation is a continuous process caused by temperaure, density and pressure (not just temperature) differentials between water and air so that the rate of evaporation accelerates when a water surface is warmed such as from the warming effect of extra greenhouse gases (especially if the air is dry).

The ocean responds by rapidly increasing the surface evaporation rate by 1.7 W.m - 2, or 2.7 g.hr - 1 of water for ideal «clear sky» conditions.

Water vapor is brought into the atmosphere via evaporation - the rate depends on the temperature of the ocean and air.

v) More CO2 ought theoretically induce faster cooling of the oceans by increasing evaporation rates.

I see discussion of ocean temperature and evaporation rates without mention of relative humidity effecting evaporation and heat content.

Instead it is a composite of the rates of evaporation and condensation, melting and freezing and thus the average time that a water molecule remains in the air in vapour form, or in the ocean as a liquid or in ice and snow as a solid.

Stephen Wilde is quite correct in pointing to evaporation from the oceans and the rate of the hydrological cycle as the pre-eminent regulator of surface temperatures on Earth in his conceptual «model.»

Conversely if downwelling IR decreases the evaporation rate decreases and the heat exchange at the ocean / atmosphere boundary remains the same.

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.

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

In fact, one almost certain effect of global warming will be an increase in the evaporation rate of the oceans.
