Abstract: This paper aims at generating a set of enriched analyses by assimilating the data collected during the South American Low-Level Jet Experiment (SALLJEX) in southeastern South America during the summer season 2002/03. The ...

Abstract: Heavy convection that occurred over Tulsa, Oklahoma, during the evening and night of 26/27 May 1984 is studied through a series of numerical experiments with a regional forecast model. The emphasis is on diurnal oscillations ...

Abstract: Prior studies have shown that the low-level jet is a recurrent characteristic of the environment during the initiation and mature stages of mesoscale convective systems (MCSs) over the Great Plains of the United States. ...

Abstract: he focus of this study is the characterization of the diurnal cycle of low-level wind and divergence field (under two different synoptic situations observed during the South American Low-Level Jet Experiment) within the ...

Abstract: A low pressure system [known as the northwestern Argentinean low (NAL)] is commonly observed over northwestern Argentina near the Andean slopes. This study describes two NAL episodes for summer and winter, with emphasis ...

Abstract: This paper concentrates on the analysis of the life cycle of the low-level jet (LLJ) during a summer Chaco jet event. This is accomplished through the use of the Eta/Centro de Previs?o del Tempo e Estudos Climáticos (CPTEC) ...

Abstract: A climatology of the South American low-level jet east of the Andes (SALLJ) is developed using the 1950? 2000 circulation and moisture fields from the NCEP?NCAR reanalyses and available upper-air observations made in Bolivia ...

Abstract: The present work focuses on the study of the environmental conditions preceding the development of a group of subtropical mesoscale convective systems over central and northern Argentina on 6?7 February 2003 during the ...
