Sentences with phrase «observed hemispheric»

Put in a two - hemisphere energy - balance model and using observed hemispheric temperature changes and ocean heat uptake changes you can easily arrive at an independent total aerosol forcing estimate - one that also implies small net total aerosol forcings that are reasonably consistent with the latest observatiional findings.

This result compares well with the observed hemispheric transport of volcanic debris leading to «the year without a summer» in 1816 in the northern hemisphere after the 1815 Tambora volcano cataclysmic eruption in Indonesia in 1815.

Observed hemispheric asymmetry in global sea ice changes.

Not exact matches

Well, something must be there, because main conservation principles are unable to account for the observed extremely precise match between all sky hemispheric albedoes, while clear sky albedoes are vastly different.

Modelers now are comparing not just hemispheric mean series, but the actual spatial patterns of estimated and observed climate changes in past centuries.

Modelers of course do not compare just hemispheric mean series, but the actual spatial patterns of estimated and observed climate changes in past centuries.

(2) The observed inter hemispheric difference between the CO2 measurements at the Mauna Loa and the South Pole stations tracks beautifully the temporal increase and variation of the fossil fuel emissions over the last 55 years.

While atmospheric GEM concentrations reconstructed from Summit firn air are higher than mean hemispheric values, they reproduce GEM levels observed shipboard between 40 ° and 50 ° N (see Fig.

Here we consider briefly some additional studies that examine the spatial structure of observed trends or use more sophisticated time - series analysis techniques to characterise the behaviour of global, hemispheric and zonal mean temperatures.

Correlation structures in surface temperature Another extension is to examine the lagged and cross-correlation structure of observed and simulated hemispheric mean temperature as in Wigley et al., (1998a).
