At +1.75 C for the entire below - surface equatorial region, the current Kelvin Wave is already approaching last year's peak values.

Not exact matches

Head does not expect to find the same icy cover in the equatorial regions of Mars where Spirit and Opportunity landed, but he hopes the «scratch and sniff» tests — in which the rovers drill into Mars rocks and compare the surface with the interior — will reveal the climatic history of the region.

As a result, the Earth's surface may have froze mostly or thinly solid through equatorial regions («Snowball» versus «Slushball» Earth hypotheses).

The increase in sea surface temperature over the central and eastern equatorial Pacific known as El Niño, and the corresponding decrease known as La Niña, contribute to seasonal climate and weather fluctuations in many regions of the globe.

Earth's surface may have froze mostly or thinly solid through equatorial regions (see debate between the «Snowball» versus «Slushball» Earth hypotheses).

The warmth was due to the near - record strong El Niño that developed during the Northern Hemisphere spring in the eastern and central equatorial Pacific Ocean and to large regions of record warm and much warmer - than - average sea surface temperatures in parts of every major ocean basin.

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..

El Niño: A phenomenon in the equatorial Pacific Ocean characterized by a positive sea surface temperature departure from normal (for the 1971 - 2000 base period) in the Niño 3.4 region greater than or equal in magnitude to 0.5 degrees C (0.9 degrees Fahrenheit), averaged over three consecutive months.

At the same time, the accelerated trade winds have increased equatorial upwelling in the central and eastern Pacific, lowering sea surface temperature there, which drives further cooling in other regions.

The NINO3.4 data represent the Sea Surface Temperature of a region in the central equatorial Pacific bound by the coordinates of 5S - 5N, 170W - 120W.

Location of the stations used for the Southern Oscillation Index (Tahiti and Darwin, black dots), the Equatorial Southern Oscillation Index (eastern equatorial Pacific and Indonesia regions, outlined in blue), and the Niño3.4 region in the east - central tropical Pacific Ocean for sea surface temperature (red dasEquatorial Southern Oscillation Index (eastern equatorial Pacific and Indonesia regions, outlined in blue), and the Niño3.4 region in the east - central tropical Pacific Ocean for sea surface temperature (red dasequatorial Pacific and Indonesia regions, outlined in blue), and the Niño3.4 region in the east - central tropical Pacific Ocean for sea surface temperature (red dashed line).

But sea surface temperature in the Equatorial Pacific region remain somewhat hotter than normal — bending toward the warm side of ENSO neutral.

If there is persistent cloud cover, as exists in some equatorial regions, much of the incident solar radiation is scattered back to space, and very little is absorbed by Earth's surface.

Hulme et al. (2001) is cited in a statement about the complexity of African climatology: «Other factors that complicate African climatology include dust aerosol concentrations and sea - surface temperature anomalies, which are particularly important in the Sahel region (Hulme et al., 2001; Prospero and Lamb, 2003) and southern Africa (Reason, 2002), deforestation in the equatorial region (Semazzi and Song, 2001; Bounoua et al., 2002)...»

«For those not in the know» La Nina is the direct consequence of the return of trade winds to their normal strength after a Nino so that renewed surface wind stress plus the Coriolis effect generate upwelling of cool water along the equatorial region: go read it up in any decent, old - fashioned text - book on physical oceanography published after about 1970....

Because the movement of the ITCZ follows the position of maximum surface heating associated with meridional displacement of the overhead position of the sun, near - equatorial regions experience two rain seasons, whereas regions further poleward experience one distinct rainfall season.

I presume the answer lies in admitting more of the complexity of real case into the computations: if not the spinning, irregularly surfaced sphere, then at least the huge differential in solar heating «twixt the equatorial and the polar regions, the great daily poleward energy transfers which compensate thanks in large part to massive convective systems.

Another simple mental picture I will yet again try to present a simplified physical picture: Our climate includes energy transport both from the equatorial region to the poles as well as a vertical flow from the surface to the height from which it can escape freely into outer space.
