The Granger causality test is used to examine the effects of the El Niño–Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO), and the North Atlantic Oscillation (NAO) on global dry/wet conditions. The results show robust relationships between dry/wet conditions and the ocean states, as assessed through a multi-index (standardized precipitation evapotranspiration index and standar...

The crystal structure of SrNa(2)(P(2)S(6))·8H(2)O is isotypic with that of its calcium analogue. The asymmetric unit consists of one Sr(2+) cation (2 symmetry), two Na(+) cations (2 and symmetry, respectively), one-half of a centrosymmetric (P(2)S(6))(4-) anion with a staggered confirmation and four water mol-ecules. The crystal structure is built up from layers of cations and anions extending ...

In this paper we discuss the atmospheric dynamics of the North Atlantic Oscillation (NAO), the zonal index, and annular patterns of variability (also known as annular modes). Our goal is to give a unified treatment of these related phenomena, to make explicit how they are connected and how they differ, and to illustrate their dynamics with the aid of an idealized primitive equation model. Our f...

in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

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...

In this work, we investigated how thermally stable ImO(N):NaN(O) and ImN(O):NaO(N) pairs are recognized by the Klenow fragment (KF). As a result, these complementary base pairs, especially the ImN(O):NaO(N) pair, were recognized selectively due to the four hydrogen bonds between the nucleobases and the shape complementarity of the Im:Na pair similar to the purine:pyrimidine base pair.

This demo presents some acts of a potential application of NAO humanoid robots under special circumstances in a hospital, including results of experiments performed at the Children's Hematology and Stem Cell Transplantation Unit of Szent László Hospital in Budapest, Hungary. Children in this unit are forced to live in small 2x3 m sterile boxes where NAO can be a good companion to cheer them up ...

Geometric and topological methods are applied to significance testing in the wavelet domain. A geometric test was developed for assigning significance to pointwise significance patches in local wavelet spectra, i.e., contiguous regions of significant wavelet power coefficients with respect to some noise model. This geometric significance test was found to produce results similar to an existing ...

The Pacific–North American (PNA) teleconnection is a major mode of Northern Hemisphere wintertime climate variability, with well-known impacts on North American temperature and precipitation. To assess whether the PNA teleconnection has extended predictability, comprehensive data analysis is conducted to elucidate PNA evolution, with an emphasis on patterns of PNA development and decay. These p...
