Aplicação da teoria da máquina térmica às brisas marítima/terrestre e de vale/montanha sobre terreno Inclinado e plano.

Abstract

breeze type circulations occur due to horizontal temperature gradient between two surfaces with different characteristics. The aim of this study was to analyze the coupling between mountain-valley breezes with sea-land breezes, applying the heat engine theory. Therefore, two regions were used with different topographical features, with a flat, one with over 800 meters of slope. The observation period was the month of June 1999, highlighting the day 2:09 that showed predominance of sea breeze and 7:17, due to the strong influence of the land breeze. The simulation results were compared with data obtained by the pressure difference theory using statistical correlation methods and applying a significance test. For increased reliability of simulations, numerical results were compared to data collected by radiosonde at 7, 9:17, at 12Z due to the accessibility of the data observed during their days. The results found in this study were satisfactory, validating the simulations as well as the heat engine theory.
