Sentences with phrase «ocean energy content»

We see ocean energy content increase or decrease as tropospheric energy content decreases or increases.

It is a given that the existing models do not fully incorporate data or mechanisms involving cloudiness or global albedo (reflectivity) variations or variations in the speed of the hydrological cycle and that the variability in the temperatures of the ocean surfaces and the overall ocean energy content are barely understood and wholly inadequately quantified in the infant attempts at coupled ocean / atmosphere models.

Thus a proportion of incoming solar energy (in the infrared) never gets into the oceans to affect the ocean heat content (I prefer the term ocean energy content and will use it from now on).

Not exact matches

However, radiation changes at the top of the atmosphere from the 1980s to 1990s, possibly related in part to the El Niño - Southern Oscillation (ENSO) phenomenon, appear to be associated with reductions in tropical upper - level cloud cover, and are linked to changes in the energy budget at the surface and changes in observed ocean heat content.

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

(2002); atmospheric energy content based on Trenberth et al. (2001); and arctic sea ice release from Hilmer and Lemke (2000).

In terms of the so - called «pause», it becomes more and more clear that the current cool phase of the PDO is largely responsible for this «pause», but looking at the continued rise in ocean heat content, and the nice job Cowtan & Way have done interpolated Arctic temperatures, we see that the «pause», may have reflected a slowdown in the rise of tropospheric temperatures, but the energy imbalance of the climate system continues quite strongly.

The current energy imbalance at the surface (as demonstrated by the increasing heat content of the oceans) implies there is at least a further 0.5 deg C surface warming in the «pipeline».

With ocean heat content, including the IPWP, running at record high levels (literally off the chart), how much energy is released in this El Niño and how quickly it fills back in is of keen interest to me.

Finally, I note that you have not acknowledged the falsification I gave in 231 of your claim that all the energy of the ocean heat content increase since 2000 was first sitting in the atmosphere in 1979.

I'd just assumed that: man's path = total ocean heat content leash length = bounds on energy transfers dog jiggles driven by ocean oscillations, solar jiggles, volcanoes...

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

Paul S (# 1)-- Since the Planck Response dominates over positive feedback responses to temperature, wouldn't a La Nina - like failure of surface temperature to rise lead to an increase rather than a reduction in energy accumulation compared with accumulation during a surface warming — presumably a small increase, so that the observed rise in ocean heat content would still be substantial?

We are just changing the order of events a bit because an increase in surface temperatures would in any case eventually increase the energy content of the oceans.

The RF time series are linked to the observations of ocean heat content and temperature change through an energy balance model and a stochastic model, using a Bayesian approach to estimate the ECS from the data.

Given that the most of the melting that goes on is from the underneath (i.e. under the water) and ocean heat content is at modern highs, and the oceans have even released a bit less energy than average over the past 15 years, it is not a coincidence that ice would de line even faster during this period.

In particular, that the energy content of the oceans should be increasing.

Anthropogenic GHG warming is about the Earth's energy balance, and thus, looking at an average global near - surface temperature, or the total ocean heat content can tell us something useful about that energy balance.

Ocean heat content increases (and the closely related sea level rise) is a far better long - term proxy for energy in the climate system.

And of course, the issue of the consistent rise in the best metric of Earth's energy balance - ocean heat content and the closely related sea level rise, get's ignored as though, through some miracle, a warming ocean holding in the bulk of the anthropogenic energy imbalance gives we troposphere dwelling creatures a free pass.

Everything else that might try to alter that base level simply results in atmospheric circulation changes (atmosphere includes oceans for this purpose) that adjust the rate of conversion between kinetic and potential energy so as to keep the base level of system energy content stable.

Hurricanes draw their energy from the ocean and warmer waters provide an increase in both temperature and moisture content of the tropical atmosphere, which leads to storm intensification.

If you take the amount of crude oil extracted since 1850 (estimates vary, but maybe 200 billion tonnes = 200 * (10 ^ 9) * (10 ^ 3) kg) and multiply by the energy density of crude oil (~ 50MJ / kg) the result comes out at about 10 ^ 22 J which is an order of magnitude lower than the increase in ocean heat content in the upper 700m since the 1950s (~ 10 ^ 23J).

Several recent studies have also concluded that it is necessary to include data from the deep ocean in order to reconcile global heat content and the TOA energy imbalance, which DK12 failed to do.

A better metric to gauge to real planetary effects of the TOA GHG induced imbalance is of course to combine combine troposphere anomalies with ocean heat content anomalies, as well as cryosphere anomalies, to get a net Earth system energy imbalance.

Flatline in total air heat content, flatline in air temperature, and yet some energy is flowing from the air into the ocean, going downwards.

For the ocean heat content to vary appreciably [the lag is a red herring], the energy input [your q] has to vary appreciably too, and it doesn't.

Given that it is all eventually going to come back to the issue of the gradual gain we've been seeing in ocean heat content over many decades, the most accurate thing we can say is that 2014's warmth is very consistent with the general accumulation of energy in Earth's climate system caused by increasing GH gases and is well accounted for dynamically in global climate models.

Theo Goodwin, the ocean heat content change doesn't average out to zero in the long term, only those internal processes you mention which shuffle energy around.
