Numerical simulations are conducted of geostrophically balanced flow over an isolated mountain cut by a horizontal gap. The relative importance of the along-gap synoptic-scale pressure gradient and terraininduced mesoscale circulations for the generation of gap winds was examined by changing the direction of the synoptic-scale wind relative to the topography. In all cases, the forcing associate...

BACKGROUND Fine-needle aspiration cytology (FNAC) is integral to the diagnosis and management of patients with thyroid nodules. We introduced synoptic cytology reporting for thyroid nodules in 2004. The aim of this study was to examine the effect of synoptic cytology reporting in our institution. METHODS A comparative study of two 2-year periods (1 August 2002 to 1 August 2004 and 2 August 20...

This article introduces the synoptic catalog, a computerized combination of a hospital library catalog and a bookseller's catalog. Majors Scientific Books and Richmond Memorial Hospital Libraries in Virginia collaborated to develop the model. A logical evolution in catalog theory and practice, the design expands the identification, collocation, and evaluation functions of the traditional librar...

This study estimated the association between particulate air pollution and daily mortality in Utah Valley using the synoptic climatological approach to control for potential weather effects. This approach was compared with alternative weather modeling approaches. Although seasonality explained a significant amount of variability in mortality, other weather variables explained only a very small ...

1 Dept. of Meteorology and IPRC, Univ. of Hawaii, Honolulu, Hawaii, USA * Corresponding author address: Prof. Tim Li, Dept. of Meteorology and IPRC, Univ. of Hawaii, Honolulu, Hawaii, USA; E-mail: [email protected] In this paper we review the observed structure and evolution characteristics of the western North Pacific monsoon on various time scales, including its annual cycle, synoptic wave act...

Abstract Weather systems in the southern Indian Ocean (SIO) drive synoptic-scale precipitation variability East Antarctica and Australia. Improved understanding of these dynamical linkages is beneficial to diagnose long-term climate changes from proxy records as well informing regional weather forecasts. Self-organizing maps (SOMs) are used group daily 500-hPa geopotential height (z500; ERA-Int...

Past climatological research has not quantitatively defined the synoptic-scale circulation deviations responsible for anomalous summer-season precipitation totals in the southeastern United States. Therefore, the objectives of this research were to determine the synoptic-scale controls of wet and dry multiday periods during the summer within a portion of the southeastern United States as well a...

The relationship between land use and stream chemistry is often explored through synoptic sampling of rivers at baseflow conditions. However, baseflow chemistry is likely to vary temporally and spatially with land use. The purpose of our study is to examine the usefulness of the synoptic sampling approach for identifying the relationship between complex land use configurations and stream water ...

introduction climate change is an important environmental hazard that has been discussed in recent years. increasing the number or frequency of extreme climatic events such as severe droughts, floods, storms, heat and cold waves and heavy rains are the evidences of climate change. any of these events, due to the severity and persistence and their spread are a natural hazard that adverse effects...
