Sentences with phrase «variations in wind patterns»

Instead, changes in the South Pole's ozone hole from year - to - year are likely the result of natural variations in wind patterns, researchers said here Wednesday (Dec. 11) in a press conference at the annual meeting of the American Geophysical Union.

There are variations in wind pattern, ocean currents and arctic melting.

Not exact matches

The pattern of wind change is complex, but variations in winds can help to explain some of the regional patterns in sea - ice formation [8].

Then there are seasonal variations in the pattern: we see much stronger wind from late winter to early summer than in the rest of the year.

Phenomena such as El Niño and La Niña — which warm and cool the tropical Pacific Ocean and cause corresponding variations in global wind and weather patterns — contribute to short - term variations in global temperatures.

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

Climate variability associated with the North Atlantic Oscillation (NAO) determines many physical coastal processes in Europe (Hurrell et al., 2003, 2004), including variations in the seasonality of coastal climates, winter wind speeds and patterns of storminess and coastal flooding in north - west Europe (Lozano et al., 2004; Stone and Orford, 2004; Yan et al., 2004).

It's a mode of natural variation in the tropical eastern Pacific ocean which is indicated by sea surface temperature in that region, as well as patterns of atmospheric pressure, surface winds over the ocean, even precipitation over a much larger region.

It implied transient variations of wind patterns within broad limits, and mostly concerned how weather might change in a particular region.

These changes will likely include major shifts in wind patterns, annual precipitation and seasonal temperatures variations.

This eastward moving pulse of anomalous variations in rainfall, wind, sea surface temperatures, and clouds in the tropics typically recurs every 30 — 60 days, creating a pattern that profoundly influences global weather and climate systems, including monsoons, tropical cyclone activity, and El Niño — Southern Oscillation events.

As noted above, patterns of large - scale variability in the extratropical atmospheric wind field exhibit variations on timescales from weeks to decades (Hartmann and Lo, 1998; Feldstein, 2000).

Defining Climate Climate = long term weather patterns... — Averages and variations in temp., precip., wind, etc..

These jet variations underlie the variability associated with patterns such as the North Atlantic Oscillation (NAO) and have considerable societal impact through variations in the prevailing westerly winds.
