Sentences with phrase «difference between the ocean and atmosphere»

So what is the difference between the ocean and atmosphere of Venus from a «pure» density / pressure, IR absorption point of view?

Not exact matches

However, it is also very noisy because a small amount of energy exchange between ocean and atmosphere make a big difference to surface temperature.

Increased warming of the cool skin layer (via increased greenhouse gases) lowers its temperature gradient (that is the temperature difference between the top and bottom of the layer), and this reduces the rate at which heat flows out of the ocean to the atmosphere.

We find that the difference between the heat balance at the top of the atmosphere and upper - ocean heat content change is not statistically significant when accounting for observational uncertainties in ocean measurements3, given transitions in instrumentation and sampling.

Is it the difference in temperature between the ocean surface and the atmosphere, or the absolute temperature of the ocean surface that encourages hurricane formation?

The current difference in pCO2 between atmosphere and oceans is about 7 ppmv (again proof that the oceans are NOT a source of extra CO2), see: http://www.pmel.noaa.gov/pubs/outstand/feel2331/exchange.shtml

Wind shear is the difference in wind speed and direction between the ocean surface and the mid-to-upper atmosphere.

It is important to mention that these processes are not uniform over the global ocean and thus the disequilibrium is not only between ocean and atmosphere, but there are also differences in radiocarbon levels within the ocean.

Some time ago, I made an estimate of the deep ocean — atmosphere exchanges to explain the difference in 13C isotope drop in the atmosphere between what was expected from fossil fuel burning and what was observed.

Yes they ad up: the natural flows in and out are huge and only rough estimates, but the difference between the natural inflows and outflows (for oceans and vegetation and all other processes together) is well known, as that is the difference between increase in the atmosphere and the human emissions.

The main difference between H2O and CO2 (apart from the numerical differences of their specific physical properites such as degree of freedom, thermal capacity, physical mass, etc) in terms of their effects on the atmosphere is that water is capable of condensing into liquid to form clouds and readily and rapidly moves between surface and atmosphere, daily, seasonally, annually and on even greater time scales, but CO2 does not liquify in the biosphere and transfers over mostly long time periods between surface (primarily oceans, seas, etc) and the atmosphere.

These two mechanisms are so strongly dependent on the temperature difference between the ocean surface ant the atmosphere that the net influence on the skin temperature and on the net heat transfer between the ocean and the atmosphere is negligible.

Its convective strength — the boiling motion of air rising from the ocean surface to the atmosphere — depends on the temperature difference between the surface ocean and the upper atmosphere.

The difference is in timing: the equilibrium between ocean surface and atmosphere is reached in 1 - 3 years half life time, but the deep oceans - atmosphere exchanges are limited in flux and need much longer periods to reach equilibrium (half life time ~ 40 years).

This is because ultimately it is the temperature differences between the ocean surface and the upper atmosphere that causes the amount of water vapour that ends up producing the heat energy in the upper atmosphere that in turn causes the instability.

This relationship is expected to change over time as the ocean warms, as the transfer of heat between ocean and atmosphere depends in part on the relative difference between them.

Consistent with the global transfer of excess heat from the atmosphere to the ocean, and the difference between warming over land and ocean, there is some discontinuity between the plotted means of the lower atmosphere and the upper ocean.

That is a matter of CO2 pressure difference (ΔpCO2) between atmosphere and oceans: the in or out fluxes are directly proportional to the CO2 pressure difference.

This is because hurricanes get their energy from the temperature difference between the warm tropical ocean and the cold upper atmosphere.

Somewhat more CO2 will leave the oceans and somewhat less will enter the oceans, but the net increase in the atmosphere still goes strong but slightly reduced, because the difference between the pCO2 in the atmosphere and the new equilibrium is now 16 microatm smaller than before.

My educated layman's physicist's gut (layman as far as climate science goes, not physics) tells me 2W / m2 out of the ocean seems pretty high given that the temperature difference is generated by a peak forcing of only -3.4 W / m2 - it implies that the ocean response is of the same order as the atmospheric response, which seems unlikely given the «impedance mismatch» between the ocean and atmosphere.

The other 23 W / m ^ 2 is due to the temperature difference between the skin of the ocean and the atmosphere with which it exchanges photons.

The basic idea was that reducing the difference in temperature between the ocean (at some fixed depth below the skin) and the atmosphere (at some fixed low altitude) through warming the atmosphere reduces the heat loss.

With steady pCO2 in the atmosphere, the pressure difference between ocean pCO2 and pCO2 of the atmosphere changes and thus the flows from one to the other.

Even if not all sinks are known to any accuracy, neither the partitioning between vegetation and oceans (one of them even may be a net source), we know with reasonable accuracy that all natural flows together form a net sink of average 3 GtC / yr (ad that is the difference between emissions and accumulation in mass in the atmosphere).

-- d13C / d14C levels don't prove that humans are the sole cause of the increase in the atmosphere, but they prove that the deep oceans are not the cause of the increase... — I did use your Segalstad example to show the difference between accumulation in % (the red dye) and the accumulation is mass (the extra inflow), all other variables being constant in total result.
