are frequently observed flowing over moister and colder currents in cases where no subsidence is indicated. For long periods of time, this warni, dry air layer can be found aloft over large sections of the country, particularly over the southern United States, and for this reason its life history presents an exceedingly important problem of synoptic meteorology. The source of this air is a cont...

A simple statistical-dynamical model relating synoptic scale changes in the meridional temperature gradient to changes in the meridional eddy sensible heat flux is developed. The model solution is compared with observations relating the flux to the stability parameter for the two layer model which, assuming the variance of the critical shear in the two layer model is negligible, is equivalent t...

This paper presents an overview of the meteorology and planetary boundary layer structure observed during the NAMBLEX field campaign to aid interpretation of the chemical and aerosol measurements. The campaign has been separated into five periods corresponding to the prevailing synoptic condition. Comparisons between meteorological measurements (UHF wind profiler, Doppler sodar, sonic aneometer...

Regular aerosol backscatter measurements using an elastic-backscatter lidar were performed from May 2000 to December 2002 in Barcelona (Spain) in the frame of EU EARLINET Project (European Aerosol Research Lidar Network). Vertical profiles retrieved in a regular schedule confirmed the presence of multiple aerosol layers of regional origin above the mixing layer during numerous measurement days....

The Large Synoptic Survey Telescope (LSST) will catalog billions of astronomical objects and trillions of sources, all of which will be stored and managed by a database management system. One of the main challenges is real-time alert generation. To generate alerts, up to 100K new difference detections have to be cross-correlated with the huge historical catalogs, and then further processed to p...

Title: Severe Convective Mesosystems in New England Author: James Elbert Kester Submitted to the Department of Meteorology on February 5, 1974 in partial fulfillment of the requirements for the degree of Master of Science. This study of convection over New England is divided into two parts. Part I is a search for a consistent mesoscale pressure pattern associated with severe convective storms o...

Obliquely rotated T-mode principal component analysis has been applied to the NCEP/NCAR geopotential height reanalysis data for winter months from 1958 to 1996 over the New Zealand region. A new set of ten representative weather types were identified, with two being the most dominant. The temporal characteristics of the ten synoptic weather types were anlayzed in relation to different phases of...
