Sentences with phrase «ohc trend»

As the ohc trend is not ubiquitous ie there is no trend in either the tropics, or NH you need another mechanism (as opposed to increased subsurface observation) eg Sutton and Roemmich

The OHC trend and surface temperature trend have been robust since 1998.

Although there is very little trend in the OHC in the subpolar North Atlantic where the salinity induced vacillation cycle dominates, there is a linear OHC trend equatorward of 45 ° N and ° S in the Atlantic basin (including the Southern Ocean)(fig.

I remember checking Wong et al. (2006) only to discover that it doesn't support your claim that OHC trend is modulated by cloud cover.

These have some cancellation due to warming tending to keep up with GHGs, but the imbalance goes into the OHC trend.

I didn't attempt to run a trend for 1990 - 2000, as OHC trend for that period was hard to read.

If you think about the fact that OHC trend is responsible for over 90 % of warming due to TOA imbalance, you may reasonably expect the surface T changes (where only 3 % of that imbalance energy goes) will not be very well correlated.

Thus the OHC trend says that surface temperature trend has further to go.

Same energy flux at the TOA, but quite a different picture for the OHC trends.

Not exact matches

The most exciting thing is we'll get a chance to see the relative strength of all of these over the next few years, and it will most interesting to compare the total decade of 2010 - 2019 to previous decades in terms of the trends in Arctic Sea ice, Global Temps, and of course, OHC.

I'm still waiting for Gates to tell me how recent OHC warming trends compare to those of 100 years ago.

OHC has a steep warming trend 1969 - 1979 (incl), has a much lower trend 1980 - 1990, and a steep trend again 2000 - 2014.

The three decadal surface temp trends behave as I imagine for periods when OHC rises quickly or is flattish.

For periods when there was a clear linear trend change in OHC (0 - 700 & 0 - 2000), there seems to be an inverse correlation with surface temperatures.

OHC 0 — 700m trends strongly upward while TSI falls...?

«A global ocean heat content change (OHC) trend of 0.55 ± 0.1 Wm ^ 2 is estimated over the time period 2005 — 2010.

The «noise level,» that is, the amplitude of internal variability, approximated here by the standard deviation (σ) of the OHC time series after the linear trend is removed, amounts to 0.77 × 1022 J from 2004 to 2015 (Table 1).

Thus, it is relatively straightforward to detect a long - term trend in OHC.

We have had these measurement long enough to know that OHC has a positive trend.

The linear trend of OHC is 0.79 ± 0.03 × 1022 J year − 1 within the same period (Figure 2).

If you can't see the problem where the measured OHC level has suddenly become adjusted to the same trend as Agenda based pre-2003 models, then you obviously have both eyes blinded by too much AGW kool - aide.

It is the north Atlantic which has gained lots of OHC and has had the most elevated SST which best matches the global trend since 1970.

As for that Fig. 4 in your 2000 Levitus paper, that is not 69 % «increase in OHC» — that is the «percent variance accounted for by this trend» (see Figure caption).

As he pointed out, a dominant unforced contribution to surface warming relative to forced trends would be expected to be accompanied by a trend of declining OHC, which is inconsistent with the observed trends averaged over the past half century as evidenced by mixed layer temperature measurements and sea level rise.

Favourite plays include hyper - focus on one, extremely speculative study (T&S 09); misrepresenting the potential for abrupt cooling in the C21st, dismissing the dominance of the centennial forced trend, misrepresenting deglacial abrupt climate change; grossly over-stating the accuracy and utility of pre-CERES TOA reconstructions (especially the synthetic, non-observational ISCCP - FD reconstruction); hyper - focus on interannual OHC variability; confusion of cause and effect with long - term trends in OHC (CO2 forcing denial) and general inability to see that natural variability from now on will be riding up a forced trend which will increasingly dominate climate behaviour.

Since 1Q2004, the OHC data show a positive trend of +3.1 ZJ / yr for the 0 - 700 m region.

I have illustrated and document that there are multiyear aftereffects of ENSO events that cause the positive trends in SST and TLT anomalies outside of the tropical Pacific, and I have shown that the rise in global OHC, when broken down into logical ocean basin subsets, is dominated by natural variables.

Considering the sampling bias, new methods to assess long - term trends in the OHC (0 — 700 m) are proposed that suggest the presence of a continuous upper ocean warming (0.36 ± 0.08 W m - 2) since 1966.»

Linear trends are particularly sensitive to the periods being analyzed [Lyman, 2012], and over such a short 8 year interval, changes in upper OHC can be strongly influenced by fluctuations in the state of the El Niño - Southern Oscillation (ENSO)[Roemmich and Gilson, 2011] and other short - term variations in the ocean state.

What remains indeed unaccounted for is the volcanic OHC imprint (which seems responsible for the trend difference between GCMs and FR11 highlighted in [Troy Masters] analysis).

However, the restoration of the volcanic OHC imbalance introduces a fairly constant (underlying) trend which is implicitly accounted for by the FR11 method.

During the altimeter period the observed 0 - 700 meter ocean heat content (OHC) in the subpolar gyre mirrors the increased SSH by its dominantly positive trend.

Especially not trends in OHC.

However, when you take long - term trends, such as seeing what happened in the last 60 years you see the big picture without the wiggles and both the SST and OHC rose.

And if you ask the question how does the OHC warming, at any depth, compare to the trend before 1950, all you get is a little deer in the headlights look.

Fig 3A is the most important chart of the page, we don't have enough historical data to make a valid trend, not do we have enough coverage now to adequately define OHC.
