1. Análise dos perfis termodinâmicos da atmosfera e de parâmetros pré-convectivos obtidos pelo satélite GOES-10 / Analysis of termodynamic profiles and pre-convective parameters obtained form the GOES-10 satellite sounder data
Meteorological satellites provide a unique opportunity to obtain thermodynamic profiles in regions of the globe that do not have a dense meteorological upper air stations network, as in South America. Nowadays, the geostationary satellite GOES-10 makes the inference of temperature and mixing radio profiles every hour with a spatial resolution of 10 km over t

3. Observational study of the low-level jet at the metropolitan region of Porto Alegre during the period 1989 to 2003. / Estudo observacional de jatos de baixos níveis na região metropolitana de Porto Alegre durante o período de 1989 a 2003
To analyze the occurrences of the Low-Level Jets (LLJ) at the metropolitan region of Porto Alegre, fifteen years of collected data of sounding between 00 and 12UTC in the period 1989 to 2003. For this, the criteria of classification proposed by Bonner (1968) and modified by Whiteman et al. (1997) have been applied. After being selected these LLJ were divided

4. Analyses of the satellite sounding data assimilation process and the impact on weather forecast using a physical-space statistical analysis system. / Análise do procedimento de assimilação de sondagens derivadas de satélites e de seu impacto na previsão de tempo utilizando um sistema estátístico em espaço físico
Many studies on evaluation of the impact of satellite sounding on forecasts, made by different institutions around the World, have shown that this kind of data are very important to improve the quality of weather forecasting in Southern Hemisphere. There are many methods of data assimilation and models of weather forecasting. In this study we used an adaptat
