  • A nao confirmaçao de fenomenos glaciarios nas montanhas do Norte de Portugal (Peneda, Gerês)
  • The relationship between North Atlantic Oscillations (NAO) and Aksu River Runoff (ARR) was investigated by using the wavelet transform (WT), cross wavelet transform (CWT), corelation and linear trend analyses, and abrupt change test. The main
  • results are : the interannual/decadal variation and period analyses of ARR and NAO reveal that the both were close correlated each other; the CWT indicates that the correlation was good between ARR and NAO at all periods in the 1990s, because
  • the significant correlation areas mainly concentrated in the 1990s; the variations in the trend strength of ARR and NAO were consistent; the abrupt change of NAO was also temporally consistent with that of ARR, which exerted impact on the Aksu River Basin (ARB
  • Winter snowfall over much of the south and central Appalachian region shows a significant inverse association with a winter index of the North Atlantic Oscillation (NAO) teleconnection pattern. The snowiest winters coincide with the negative phase
  • of this pattern. The aim of this paper is to answer questions such as : does the snowfall-NAO association hold up over a longer period of record? If so, is this association based on NAO-related variations in temperature, precipitation or storm tracks?

  • L'influence de l'oscillation nord atlantique (NAO) sur les variations journalières de la pression atmosphérique en Pologne
  • linear regression, it proved possible to determine the statistical linkage between values for the NAO Index and day-to-day pressure changes of this magnitude, month by month and in the adopted December-March winter period. – (BJ)

  • . However, cold front passage frequencies during El Niño and La Niña events are not significantly different. The Pacific/North American (PNA) and North Atlantic Oscillation (NAO) teleconnection patterns exert a significance influence on cold front
  • variability in this region. The PNA pattern is most strongly tied to variations in cold front passage frequencies in Florida. Various parts of the southern United States are affected by the NAO.

  • the influence of climate conditions (temperature, precipitation, and NAO indices) on tree-ring development in an attempt to find out the sign and strength of the limiting climatic growth-controlling factor. These species have not been used previously
  • to reconstruct the NAO variability from Iberia. Therefore the AA. assess the usefulness of these tree species for expanding the use of new tree-ring data in multi-proxy reconstructions of the NAO.
  • Short-term beach rotation, wave climate and the North Atlantic Oscillation (NAO)
  • regimes, together with major climatic variations expressed by the NAO index, are utilized to evaluate processes governing short-term beach rotation phenomena. Significant research findings are assessed with relevance to other coastal locations worldwide
  • Le climat variable de la Pennsylvanie est expliqué par deux types de variations climatiques : des variations interannuelles se rapportant aux deux modèles (Pacific North American : PNA| North Atlantic oscillation : NAo) et des variations
  • and features of the circulation, such as the NAO (North Atlantic Oscillation).
  • Changes in extreme temperature and precipitation in the Arab region : long-term trends and variability related to ENSO and NAO
  • Atlantic Oscillation (NAO). No statistically significant correlations were determined between ALT and monthly precipitation and cloudiness at Barentsburg, Hornsund and Svalbard Airport stations. There were, however, very strong and highly significant
  • between ALT and air temperature at Svalbard Airport, the time series of ALT at Calypsostranda is reconstructed from 1911 to 2010. It was also found that the AO and the NAO did not significantly affect ALT and air temperature on western Spitsbergen.

  • L'analyse de cent hivers à l'aide de diagrammes permet d'étudier les variations de température et de couverture neigeuse, ce qui conduit à mesurer l'influence de l'oscillation nord-atlantique (NAO, North Atlantic Oscillation). Un parallèle est

  • The main focus lies with climatic and hydrologic implications of the major circulation patterns in the northern North Atlantic, namely the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO). The studies reviewed here reveal key
