Sentences with phrase «latitudinal temperature gradient»

Rind, D., M. Chandler, J. Lerner, D.G. Martinson, and X. Yuan, 2001: Climate response to basin - specific changes in latitudinal temperature gradients and implications for sea ice variability.

The result was a substantial decrease in the lower - tropospheric latitudinal temperature gradient.

This increased climate sensitivity at high latitudes has resulted in a greatly reduced latitudinal temperature gradient (Fig. 3A).

These elevated Arctic Pliocene temperatures result in a greatly reduced and asymmetrical latitudinal temperature gradient that is probably the result of increased poleward heat transport and decreased albedo.

Indeed, physical theory would lead us to expect just that, with a relatively stronger greenhouse effect decreasing latitudinal temperature gradients.

Higher latitudes during Southern Hemisphere winter receive no such augmentation, and the increased latitudinal temperature gradient results in stronger stratospheric west winds.

Most of the focus has been on the global mean temperature trend in the models and observations (it would certainly be worthwhile to look at some more subtle metrics — rainfall, latitudinal temperature gradients, Hadley circulation etc. but that's beyond the scope of this post).

Cors Fochno is strongly influenced by westerly moving storms, so it is suggested that the patterns were due to variations in the intensity of westerly airflow and atmospheric circulation during times when the latitudinal temperature gradient was steepened.

«Our study is the first to point out that the lack of a latitudinal temperature gradient within the tropics has a serious consequence for small - ranged tropical species: many would have to shift thousands of kilometres north or south to maintain their current climatic regime in a warming climate.»

While the canonical view is that latitudinal temperature gradients will decrease as climate warms (greater warming at high latitudes), increased gradients in the Pacific could result from semi-permanent El Niño conditions as simulated by some models; increased gradient in the North Atlantic could arise from decreased ocean circulation (i.e., North Atlantic Deep Water production) as also occurs in some models.

They find that sea surface temperature was up to 4.5 oC warmer than present and that the latitudinal temperature gradient for the southwest Pacific is consistent with persistent La Nina and positive Southern Oscillation Index conditions.

Therefore, the decreased temperature gradient can be explained in part by increased poleward heat transport, but other physical mechanisms must be invoked to explain the observed asymmetry in the latitudinal temperature gradient.

Most of the observed decline in the latitudinal temperature gradient during the Pliocene can be explained by increased poleward heat transport.

Thus the differential magnitude of ice - albedo feedbacks between the Arctic and Antarctica may help to explain apparent asymmetries in the latitudinal temperature gradient.

This pronounced Arctic tail in the latitudinal temperature gradient can be explained in part by a greater ice - albedo feedback in the Arctic compared to Antarctica.
