The present work aims at examining the association of nighttime temperature inversions and synoptic-scale circulation in the Athens basin. Temperature inversions have a direct impact in the diffusion and transport of pollutants, a fact that highlights the importance of investigating their cause effect relationship. For this purpose, randiosonde measurements from the upper-air station in Hellini...

A strong relationship is observed between synoptic weather systems and atmospheric forcing of the ocean as estimated from buoy measurements made on the North Carolina inner shelf during August and October-November 1994 as part of the Coastal Ocean Processes (COOP) Inner Shelf Study. Synoptic variation (timescales of days to weeks) in the meteorological time series was primarily associated with ...

HYPOTHESIS As opposed to the traditional dictated report, the use of a computer-based synoptic operative report will mandate that the surgical resident have a better understanding of all facets of the procedure. DESIGN A prospective study over a 10-month period. SETTING A 636-bed community teaching hospital. PATIENTS A total of 57 consecutive patients and 60 operative procedures for breas...

Selected hourly surface observations from Madison, Wis. and Minneapolis-St. Paul, Minn. are used as basic data for a series of analyses t o determine the feasibility of establishing weather classifications. Component analysis (factor analysis) is applied to a sample of January data for Madison to reduce the number of variables needed to suitably describe each day meteorologically and to create ...

This study presents a synoptic classification at surface and 500 hPa during the winter (June, July, August) over Brazil, in order to identify main synoptic-scale meteorological systems that influence weather of this period. Through Principal Components Analysis (PCA) for 1979-2020 period, it was identified five patterns predominated which are practically same each three analyzed months. The mos...

This study, adopting an environmental approach to atmospheric circulation, estimates drought periods over a 20-year period (1992-2011) in 21 synoptic stations in Kerman, Yazd and Isfahan provinces, which share a long-term statistical period, using Standardized Precipitation Index (SPI). The data pertinent to 18 teleconnection patterns were derived and compared with climatic data of provinces un...

Abstract Arctic amplification refers to the greater surface warming of than other regions during recent decades. A similar phenomenon occurs in troposphere and is termed “tropospheric amplification” (TAA). The poleward eddy heat flux moisture are critical warming. In this study, we investigate synoptic transient activity over North Pacific associated with TAA its relationship subtropical jet st...

For a synoptic analysis of high polluted days in 13 and 14 November 2007, a combinatorial synoptic analysis was used. From methodology prospect, the present study has utilized the "circular environment" synoptic approach and with respect to the restrictions on very high-polluted days in Mashhad city, the subjective synoptic analysis used for data processing and analyzing the prevailin...
