Condensa??o a superfície na Amaz?nia em área de pastagem durante o experimento LBA/SMOCC: estudo de casos

摘要

The condensation is an indispensable variable to the knowledge of some hydrologic and biologic process which is involved in a great natural process variety, which acts in different space and secular scales. In the Amazon is common to see such phenomenon on the dawn period, mainly in dry times. Inside the structure of Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), the Smoke, Aerosols, Clouds, Rainfall and Climate (SMOCC) campaign was realized in a period between September and November 2002, on the old ABRACOS's small experimental farm, located in Rond?nia, where was possible to make detailed measurements from of the chemical and physical properties of the atmosphere, the formation and waste of water vapor's surface. According to the results, the condensation formation occurred during nocturnal period for presenting propitious conditions for its event. To the events analyzed in this work, it was observed that its formation and maintenance had been in function of the wind intensity. However, it is possible to argue that the calmness is a determinative factor for the condensation sprouting.
