Sentences with phrase «high northern latitudes due»

The main reason for this warmer climate was an increased amount of energy from the Sun being received at high northern latitudes due to Earth's orbital configuration, plus Earth had an increased capacity to absorb heat due to vegetation changes and reduced ice and snow cover.

Not exact matches

For the change in annual mean surface air temperature in the various cases, the model experiments show the familiar pattern documented in the SAR with a maximum warming in the high latitudes of the Northern Hemisphere and a minimum in the Southern Ocean (due to ocean heat uptake)(2)

Another seemingly useful clue is that, during a period of methane doldrums (no rise) from 1999 - 2002, the N / S gradient of methane relaxed a bit [Dlugokencky et al., 2003], suggesting that the doldrum was due to a decline in a methane source in the northern high latitudes.

ENSO is ultimately driven by change in sea surface pressure at high latitudes due to the coupled circulation of the stratosphere and troposphere and the inter annual variations in ENSO relate to what we know as the Southern Annular Mode and the Northern Annular Mode.

For example, mechanisms evaluated in this work revealed a cooling trend in Eurasia due to forest loss in western North America; this finding, however, contrasts with evidence of a warming trend in the Northern Hemisphere high latitudes with increased CO2 concentrations [45] that result in shifts in boreal forest range and disturbance regime [46].

For the change in annual mean surface air temperature in the various cases, the model experiments show the familiar pattern documented in the SAR with a maximum warming in the high latitudes of the Northern Hemisphere and a minimum in the Southern Ocean (due to ocean heat uptake) evident in the zonal mean for the CMIP2 models (Figure 9.8) and the geographical patterns for all categories of models (Figure 9.10).
