Abstract. The efficacy of Euro-Atlantic circulation regimes for estimating wintertime climate anomalies (precipitation and surface temperature) over Europe is assessed. A comparison seasonal reconstructions from two different regime frameworks (cluster analysis the low-level zonal flow, traditional blocking indices) presented contrasted with using North Atlantic Oscillation (NAO) index. are qua...

background: vertebrobasilar arterial territory nourishes one-quarter of human brain. it constitutes some vital and strategic parts of the central nervous system. methods: a number of keywords (vertebral, basilar, artery, and territory) were searched in medline (ovid and pubmed) as well as google, proquest, scopus, cochrane library, and science direct online databases. only articles containing a...

as widespread deserts is located in west and southwest of iran plateau, dust storms form due to west andsouthwest systems over syria or iraq as well as arabian peninsula. these systems severely affect west and southwestregions. sometimes the fine dusts transmit to central, north east, and east regions. in this study for investigating dustysynoptical patterns, meteorological data at 5 synoptic s...

The relationship between monthly midtropospheric circulation variations, occurring in the North American sector, and surface temperature and precipitation across the Great Plains is evaluated for the middle month of each season (January, April, July, and October). The results demonstrate that monthly Great Plains temperature variability is strongly associated with the majorpattems of midtroposp...

the aim of this research is recognizing synoptic patterns of the level 500 hp occurrence of late spring freezes over kurdistan province during 1965-2005. after determining freeze temporal-spatial threshold, 22 freezing days spreading over the region were extracted. then, level 500 hp height data located in a scope of 25-60 northern latitude and 30-60 eastern longitude was formulated as an s-mod...

We employed a novel method that combined probabilistic analysis and spatial modeling assisted by GIS to analyze the risk of extreme precipitation in Northeast Spain related to three atmospheric circulation configurations: the North Atlantic Oscillation (NAO), Mediterranean Oscillation, and Western Mediterranean Oscillation (WeMO). The analysis was performed at an event-based scale using data ob...

Analyses of discharge series, precipitation fields and flood producing atmospheric circulation patterns reveal that two governing flood regimes exist in the Mulde catchment in south-eastern Germany: frequent floods during the winter and less frequent but sometimes extreme floods during the summer. Differences in the statistical parameters of the discharge data can be found within the catchment ...

SUZUKI, H., KAWAKAMI, Y, and FUJITA, M. Electroencephalographic Patterns Related to Hemodynamic Changes at the Onset of Cardio-Pulmonary Bypass Circulation. Tohoku J. Exp. Med., 1991, 164(4), 331-337 Electroencephalographic (EEG) changes in relation to hemodynamic changes at the onset of cardio-pulmonary (C-P) bypass circulation in 31 cases undergoing open heart surgeries were studied. Rapid an...
