Sentences with phrase «heat uptake»
"Heat uptake" refers to the process of absorbing or taking in heat. It means that something is gaining warmth or energy from its surroundings. Full definition
Our results hence point at the key role of the ocean heat uptake in the recent warming slowdown.

The rate of heat uptake by the ocean provides the link between the SST and global average temperature.
And I would like to understand the effects of internal variability on heat uptake a lot better.
He notes that the high end is driven by uncertainties in the oceanic heat uptake data earlier in the record.
This was due to a combination of factors: a less active sun, higher levels of cooling aerosols from volcanoes and Asian factories, and increased heat uptake by the oceans.
Hence the deduction of the estimated change in ocean heat uptake from the estimated change in forcing before comparison with the change in global temperature to derive sensitivity.
The cycle of extra heat uptake by the oceans may be over for at least a decade.
New research shows that ocean heat uptake across three oceans is the likely cause of the «warming hiatus» — the current decade - long slowdown in global surface warming.
Over long time periods, this tropical heat uptake is roughly balanced by heat release from the ocean to the atmosphere in other regions closer to the poles.
The only reason why ocean heat uptake does have an impact is the fact that it is highly concentrated at the surface, where the warming is therefore noticeable (see Fig. 1).
Let's think about the implications for ocean heat uptake.
Even extending to pre-Argo periods, with a long period the errors in ocean heat content values have to be very large to have a major effect on the mean rate of heat uptake over the period.
The authors note that more than 85 % of the global heat uptake (Q) has gone into the oceans, including increasing the heat content of the deeper oceans, although their model only accounts for the upper 700 meters.
The ocean heat uptake comes into play only when one is trying to explain why the structure of the warming in models changes in time — that is, why the high latitude warming is delayed.
The CERES radiation data shows net heat input for January but their absolute values are doubtful and January always has more heat uptake due to the sun being over more ocean.
«Therefore, unless models miss effects of other forcing agents, it is likely that this [less efficient ocean heat uptake] process will occur and act to accelerate surface warming in coming decades.»
Although Gregory 02 ignored non-ocean heat uptake, some allowance should be made for that and also for any increase in ocean heat content below 3000 m.
But a quick computation suggests that with ECS at 1.6 C and reasonably mainstream ocean heat uptake parameters, TCR would likely be in the range 1.25 -1.4 C.
Trenberth only thinks there's 50 % more heat uptake by the ocean than Hansen does.
As far as there being a «guarantee», all I can say is that I personally have no idea on how to create a consistent model dominated by internal variability — ie., a model with low climate sensitivity, a trend pattern similar to observations, and a positive heat uptake — as I tried to outline in this post.
