Sentences with phrase «fixed sst»

«Fs», the fixed SST forcing, is a combination of the flux change at the top of (and throughout) the atmosphere and of the global surface air temperature change after the forcing and with observed sea surface temperature (SST) and sea ice (SI) held fixed.

In principle multiple runs would be desirable, but as equilibrium is reached quickly with fixed SST it looks aas if they have instead, for each forcing, averaged across 3 decades from the same run.

The available data include the climate responses to each of the forcings for fixed SST simulations («Fixed SST Response») as well as for the interactive coupled atmosphere - ocean model («100 - Year Response»).

And I don't think they have archived the fixed SST runs involved — they don't seem to be in the CMIP5 archive.

Cartoon comparing (a) Fi, instantaneous forcing, (b) Fa, adjusted forcing, which allows stratospheric temperature to adjust, (c) Fg, fixed Tg forcing, which allows atmospheric temperature to adjust, (d) Fs, fixed SST forcing, which allows atmospheric temperature and land temperature to adjust, and (e) DTs, global surface air temperature calculated by the climate model in response to the climate forcing agent.»

Shine et al. (2003) extended the fixed SST approach to what they call «adjusted troposphere and stratosphere forcing.»

I guess the best way would be somehow to fix SSTs just in your warm pool somehow, I'm sure some folk at NCAR have done this before.

In contrast, the MBL shallows or even becomes cloud - free under the traditional fixed - SST approach (Figure 2, the «SST» cases).

The traditional approach is to fix the sea surface temperature (SST) and free - tropospheric conditions, which are then perturbed to mimic global warming (e.g., Rieck et al. 2012; Blossey et al. 2013).

In Tan et al. (2016a), we show that all three low - cloud regimes under the present climate are well simulated by both our new slab - ocean approach and the traditional fixed - SST approach.

Ideally the zero point would be modulated by ocean heat content and / or ssts, since it is the comparison between energy into the oceans vs. energy radiated back out that determines warming or cooling, but we don't have much historical ohc or sst data so a fixed zero point would seem to be the best that can be done.

So I'm prompted to wonder... Since 1970, fewer, larger ships reporting SST from fixed (intake / hull) sensors — could this intruduce a warming bias in the recent observed SST data?

However, in the deep tropics, where the theoretical effects on the surface energy budget of temperature - driven changes in evaporation and water vapour are particularly strong, there is a near quarter century record of both SST and tas from the Tropical Atmosphere Ocean array of fixed buoys in the Pacific ocean.

The fixed buoys data enables a proper comparison of SST and tas trends to be made, since the measurements are co-located.

It defines ERF similarly to Hansen's Fs, but with no adjustment made for the change in land temperature (which is modest when SST is fixed), and notes that ERF can also be estimated by regression, as for Fs *.

ERFs were estimated only for the year 2000, from simulations with the then level of the forcing agent concerned and only SSTs fixed at 1850 values.
