Estudo de ondas atmosféricas observadas de dados de vento pelo método da análise de hodografo.

Abstract

The main objective of this dissertation work was the analysis of waves conditions in the equatorial mesospheric region in São João Cariri-PS (7.4o S; 36.5° O) through wind data collected between January and December 2005 by the SkiYMET meteoric radar installed at the Atmospheric Luminescence Observatory from Paraiba (OLAP). To estimate the main wave parameters, it was applied the technique of hodograph analysis on the data of the horizontal components of the wind. This technique is widely applied in the study of almost monochromatic waves. You The results obtained showed five elliptical hodographs, thus suggesting the presence of atmospheric waves with a certain degree of polarization. these waves showed periods approximately between 17 and 50 h and wavelengths horizontal approximately between 4000 and 15000 km. In this work, such waves were classified as gravity-inertia wave.
