An observational study of the energetics and dynamical aspects of GATE cloud clusters

Creator:

Wang, Jough-tai

Abstract:

Thermodynamical and dynamical aspects of tropical cloud clusters are studied using data from the GARP Atlantic Tropical Experiment (GATE). The data set used in this study is a three-dimensional gridded set of upper-air analyses constructed by Ooyama and Chu (Hurricane Research Division, AOML/NOAA and SSEC-University of Wisconsin) for wind data...

Dissertation
Statistical relationships between the mesoscale organization of convection, precipitation and the large-scale wind fields during the GATE

Creator:

De Silva, Sirilath J.

Abstract:

Data from the GARP Atlantic Tropical Experiment (GATE) was analysed in an exploratory manner to discover the characteristics of mesoscale organization of convection and it's relationship to large-scale wind profiles. Automated methods were developed to identify the convective cells and their linear organization. These automated methods use a median high-pass...

A study of positive cloud-to-ground lightning flashes in mesoscale convective systems

Creator:

Lu, Chungu

Abstract:

This study is mainly concentrated on examining the positive cloud-to-ground lightning activity associated with Mesoscale Convective Systems. Six MCS events which occurred during the O.K. PRE-STORM program in 1985 are studied. Data indicating the location and polarity of the cloud-to-ground lightning flashes from a lightning location network are analyzed in...
