Sentences with phrase «latitude polar regions»

Not exact matches

The negative phase brings higher - than - normal pressure over the polar region and lower - than - normal pressure at about 45 degrees north latitude.

I am arguing that because the area of the polar region (higher than latitude 60) is approximately a third of the area of the tropics (lower than latitude 30), then the global temperature will be dominated by that of the tropics.

Over the last 35 years, our research team has recovered ice - core records of climatic and environmental variations from the polar regions and from low - latitude high - elevation ice fields from 16 countries.

In the case of Saturn the temperatures predicted by models of solar heating are 200 K, compared to temperatures of 400 K observed independently in the polar regions and at 306 latitude.

This helps the middle latitude jet stream to blow strongly and consistently from west to east, thus keeping cold Arctic air locked in the polar region.

By convention, the high index polarity of the annular modes is defined as lower than normal pressures over the polar regions and westerly wind anomalies along ~ 55 - 60 degrees latitude.»

In the very high latitudes of the north polar region the temperature change is declining with latitude rather than increasing.

T0 can be taken as more or less constant near 255 K while P0 is latitude dependent near 400 mbar at the equator, and near the ground in the polar regions (as there there is very little water vapour and the optical thickness of the air on most of the thermal infrared spectrum is low).

It is, however, projected that some low - latitude and polar regions will experience net costs even for small increases in temperature.

Since the major dust sources are located in northern subtropical latitudes, the direct effect is mainly concentrated in these regions (11), although polar regions are sensitive to amplified high - latitude variability in dust concentrations (12).

Figure 3 compares the GISS analysis of global temperature change with the case in which the polar regions, specifically regions poleward of 64 degrees latitude, are excluded from the analysis.

As expected, amounts of precipitable water are greatest over warm, equatorial regions and decrease more or less continuously with increasing latitude down to very low values over the cold, polar regions.

Middle latitude monthly temperature variation is greater than in polar or tropical regions.

In contrast to the polar regions, the network of lower latitude small glaciers and ice caps, although making up only about four percent of the total land ice area or about 760,000 square kilometers, may have provided as much as 60 percent of the total glacier contribution to sea level change since 1990s (Meier et al. 2007).
