Not exact matches

Professor Baldwin added: «Natural large pressure fluctuations in the polar stratosphere tend to last a long time — at least a month, and we see this reflected as surface pressure changes that look very much like the North Atlantic Oscillation — which has significant effects on weather and extreme events across Europe.»

As changes happen in the polar regions, they are carried around the world by ocean currents, both at the surface and in the deep ocean.

The study simply wasn't aimed at identifying any causes of mass loss — it merely observed these losses using NASA's twin GRACE satellites, which measure mass and gravitational changes at the Earth's surface, and tied them to the resulting polar motion.

Multiyear records of remotely sensed tDOM distributions provide direct evidence of how the routing, inventory, storage and residence time of tDOM in surface polar waters change in response to climatic forcing.

By facilitating the real - time, synoptic monitoring of tDOM and freshwater runoff in surface polar waters, this novel approach will help understand the manifestations of climate change in this remote region.

Although there is still some disagreement in the preliminary results (eg the description of polar ice caps), a lot of things appear to be quite robust as the climate models for instance indicate consistent patterns of surface warming and rainfall trends: the models tend to agree on a stronger warming in the Arctic and stronger precipitation changes in the Topics (see crude examples for the SRES A1b scenarios given in Figures 1 & 2; Note, the degrees of freedom varies with latitude, so that the uncertainty of these estimates are greater near the poles).

Aren't those cyvlones not only steadily tugging more on the earth's surface on our seas (e. g. the so - called monsterwaves) but pulling also on our firm crust in certain places, thereby provoking unusual outbreaks of volcanoes, like in Iceland, and with that maybe also causing every more a little change on the polar axis of our planet?

There are three large average surface wind patterns few know about: the tropical easterlies (tradewinds), the midlatitude westerlies and the polar easterlies, but variability results in significant weather changes.

When polar ice melts the earth changes shape: mass (ice) which was concentrated at the poles, with a short arm of inertia, is spread evenly around the ocean surface, averaging something like 63 degrees latitude.

More or less upwelling in the eastern Pacific is linked to changes in wind and gyre circulation — in both hemispheres — driven by changes in surface pressure in the polar annular modes.

AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing water mass from equatorial latitudes and transporting this water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..

Because the GISS analysis combines available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in polar regions where observations are limited.

The puzzle of a shared 20 to 30 year pulse in both hemispheres is traced mechanistically back to changing polar surface pressure fields — influencing storm tracks in high latitudes.

Storms and cloud spinning off the polar vortices into lower latitudes — the changes in sea surface temperature over vast areas of the Pacific.

Also, as far as temperature changes across the year are concerned, in the polar regions right at the surface, the main warming will be in the winter months.

As the polar ice caps grow or melt, the surface area of the earth covered by land relative to that covered by water changes.

The changes in the solar magnetic field impacting the Earth at polar regions cause changes in surface pressure.

The more recent suggestion is that it is triggered by changes in polar surface pressure which modulate wind and ocean currents in both the north and south hemispheres.

Climate forcings due to past changes in GHGs and surface albedo can be computed for the past 800000 years using data from polar ice cores and ocean sediment cores.

As the Earth's surface cools further, cold conditions spread to lower latitudes but polar surface water and the deep ocean can not become much colder, and thus the benthic foraminifera record a temperature change smaller than the global average surface temperature change [43].

Furthermore warm ocean surfaces really do send the air circulation systems poleward whilst changes in the intensity of the polar high pressure cells work in opposition to those oceanic effects.

In accordance with that proposition the ocean surface temperatures change cyclically and the polar atmospheric oscillations change cyclically.
