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 ...

The effect of the advection of magnetic features on synoptic frames has been estimated and it shows that for the time interval ranging from 4 to 14 days the differential rotation of magnetic features accounts for most of the surface transport of photospheric magnetic fields. It is shown that both the 1996.08.27 19:12:30 synoptic frame with the effect of differential rotation included and the fo...

[1] In this paper, by using a dynamic model with synoptic eddy and low-frequency flow (SELF) interaction, we show that the SELF feedback is of significant importance for the formation of the AO/NAO in both winter and summer. Although background storm activity is significantly weaker in summer than that in winter, the positive SELF feedback associated with the AO/NAO mode in summer can be as str...

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 ...
