Sentences with phrase «recent positive phase»

Most SRES - based climate scenarios show a continuation of the recent positive phase of the NAO for the first decades of the 21st century with significant impacts on coastal areas (Cubasch et al., 2001; Hurrell et al., 2003).

The readings revealed a shift in the Antarctic Oscillation (AAO), the seesawing pattern of pressure that controls the winds around the South Pole: in recent years, it seems, the AAO has been spending more time in its positive, strong - wind phase.

As the AMO has been in a positive phase since the early 1990s, it may have contributed to the extreme winters that both the US and Europe have experienced in recent years.

Thompson and Solomon (2002) showed that the Southern Annular Mode (a pattern of variability that affects the westerly winds around Antarctica) had been in a more positive phase (stronger winds) in recent years, and that this acts as a barrier, preventing warmer air from reaching the continent.

Similarly, if as a number of recent studies suggest, anthropogenic climate forcing leads to a greater tendency for the positive phase of the North Atlantic Oscillation (NAO)[or related «Arctic Oscillation» (AO)-RSB- pattern, we would expect increased baroclinicity and storminess over a substantial region of the mid-latitude North Atlantic ocean and neighboring western Europe..

If the increasing number of sunspots would bring the Arctic index into «a positive phase» as well, then temperature isolation of the High North would in the winters months improve compared to recent years [which brought temperature records over Greenland and the Arctic Ocean — and a smallest ice extent last winter], perhaps allowing for some extra sea ice recovery.

Recent accelerated warming of the Arctic results from a positive reinforcement of the linear warming trend (due to an increasing concentration of greenhouse gases and other possible forcings) by the warming phase of the multidecadal climate variability (due to fluctuations of the Atlantic Ocean circulation).»

Based on the ENSO and PDO variability during the altimeter record, a positive acceleration is expected due both to the presences of two large El Niños at either end of the record and the recent shift from the positive to negative phase of the PDO.
