Sentences with phrase «high latitudes»

For the month shown, an exception occurs for snow - covered regions at high latitudes in the northern hemisphere.

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

He began seeing firsthand the impacts of climate change at high latitudes where the sea ice is melting rapidly due to human - caused global warming.

Increased melting from high latitudes should produce an identifiable pattern of sea level change («fingerprints») that may provide evidence of an acceleration in the rate of sea level rise.

The pattern of future warming where land warms more than the adjacent oceans and more in northern high latitudes is seen in all scenarios.

Many species simply expanded their ranges into higher latitudes, and mammals and plants were able to move into new continents.

The significance is that one can readily observe the extent and intensity of the cold air covering the northern high latitudes as a whole at the time and date of each map.

As can be seen, coverage at high latitudes during winter is poor mainly because the sun is not high enough over the horizon.

Anyone at high latitudes makes far less vitamin D per minute of sun exposure.

We might expect that as ocean temperatures warm at higher latitudes more tropical storms could persist farther north.

Climate models suggest that atmospheric carbon dioxide concentrations would need to increase, at the very least, by 1,000 parts per million, to warm high latitudes by 8 to 10 degrees Celsius.

Some of these northern high latitudes experienced monthly averages 10 - 15 °C (18 - 27 °F) above normal.

We argue that how drought affects tree mortality in forests of high latitudes remains an open question and more studies are needed.

The temperature of higher latitudes probably shows more natural variability because it takes a smaller variation in energy flux to change the temperature where it is colder.

In addition, the temperature gradient between low and high latitudes governs many features of atmospheric dynamics, the movement of winds and storms.

[9] Therefore, the effect of excluding higher latitudes from the predictor field seemed worth investigating.

That's because the lower sun angle at higher latitudes negatively affects solar thermal field performance.

The tree rings used for temperature are from trees at quite high latitudes, where temperature has historically been the limiting factor.

The study also notes that global warming is greatest at higher latitudes near the poles.

A rise in mean temperature in high latitudes should increase the duration of the growing period and the productivity of these regions if light and nutrient conditions remain constant.

When a particular combination of the orbital elements is reached, high latitudes of the northern hemisphere begin to experience year round snow.

Just look at the housing and clothing people wear in the tropics compared with at high latitudes.

But also keep in mind that Lambeck et al (2002) have suggested that loss of permanent ice over the Arctic Sea at the end of the last interglacial allowed for increased accumulation of snow and ice at high latitudes because of the increased amount of moisture available.

For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions.

Auroras are lightshows that typically occur at high latitudes such as the Arctic and Antarctic; however, they expand equatorward under severe magnetic storms.

I wasn't aware how much error there was in cloud cover with far fewer clouds predicted by the physics models than the clouds actually observed, except in the very high latitudes where they predict far more than actually observed.

In addition to ozone losses of 25 percent to 40 percent at mid-latitudes, the models show a 50 percent to 70 percent ozone loss at northern high latitudes -LSB-...]

There is pretty good evidence in the tropical ocean paleo that the LIA was about a degree cooler in ~ 1700 and since higher latitudes tend to amplify tropical advection, global temperatures could have be more than 1 C cooler.

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].

The most recent news making events are two: a challenge to the dates that have been assigned to Neanderthal remains closest to the time of their extinction; and a claim Neanderthals occupied a site in the Siberian far North, at much higher latitudes than previously thought possible.

The net result is that in the lower troposphere, the temperature difference between low and high latitudes decreases as the planet warms, creating less wind shear.
