The North Atlantic Oscillation (NAO) is one of the major sources of interannual atmospheric variability over the Northern Hemisphere. In this study, we examined the variability of lake-levels of Lake Bey ehir in timescale (period) domain using continuous wavelet transform (CWT) and global wavelet spectrum (GWS). The long winter (December, January, February and March) lake-level series and NAO i...

The combined influence of the North Atlantic Oscillation (NAO) and East (EA) patterns on covariability temperatures precipitation in 35 stations Iberian Peninsula during period 1950–2019 is analysed this work. Four EA-NAO composites were defined from teleconnection patterns’ positive negative phases: EA+NAO+, EA+NAO-, EA-NAO+ EA-NAO-. Daily data maximum minimum temperature used to obtain season...

Temporal and spatial variability of annual seasonal precipitation from 71 stations located in Western Balkan (WB) countries (Serbia, Bosnia Herzegovina, Montenegro) their correlations with nine atmospheric circulation patterns was examined for the period 1950-2016. Annual increased significantly throughout WB (from 2% to 8% per decade) on 20% mainly mountainous western Serbia eastern Herzegovin...

introduction long-term annual extreme climate events, especially temperature and precipitation, have generally been used as indicators for the assessment of climate change. one of the most changeable climatic variables in time and space is precipitation. there are great number of research papers focusing on extreme precipitation on global, regional and national scales have been written. the res...

The to equation method based on an equivalent isobaric geopotential height in t• coordinates has been used to retrieve the precipitation over Greenland. This approach is designed to accurately represent the topographic effects of the Greenland Ice Sheet on atmospheric motion and precipitation. The 11 year mean precipitation from 1985 to 1996 over all of Greenland is 376 mm yr -• which is close ...

The impact of El Niño–Southern Oscillation (ENSO) on the North Atlantic (NAO) has been controversially discussed for several decades, which exhibits prominent seasonality and nonstationarity. During early winter, there appears a positive ENSO-NAO relationship, while this relationship reverses its sign in late winter. Here, we show that subseasonal variation could be attributed to different mech...

Herein I propose a multi-scale dynamical analysis to facilitate the physical interpretation of tide gauge records. The technique uses graphical diagrams. It is applied to six secular-long tide gauge records representative of the world oceans: Sydney, Pacific coast of Australia; Fremantle, Indian Ocean coast of Australia; New York City, Atlantic coast of USA; Honolulu, US state of Hawaii; San Di...

Causal discovery seeks to recover cause–effect relationships from statistical data using graphical models. One goal of this paper is to provide an accessible introduction to causal discovery methods for climate scientists, with a focus on constraint-based structure learning. Second, in a detailed case study constraintbased structure learning is applied to derive hypotheses of causal relationshi...

We explored the possible effects of the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) on interannual sea surface temperature (SST) variations in the Alborán Sea, both separately and combined. The probability of observing mean annual SST values higher than average was related to NAO and AO values of the previous year. The effect of NAO on SST was negative, while that of AO was pos...
