Estudo sobre a turbulência na camada limite planetária

Abstract

In this research was made a study about the development of the boundary layer in Pedras Altas – RS. This study is made in two parts, fist a theoretician introduction then some datum, collected from a meteorological tower, where we compare this practical and theoretician parts. But this theoretician introduction includes the ideal development of the boundary layer structure, with a define turbulence associated, and the collected datum does not present such this ideal development. Even when this datum does not present that ideal development, with all this asymmetry we had a very good confrontation between datum and theoretician elements at all. This research focus was exactly the turbulence associated with the boundary layer, which is evident when the collected datum is about the wind speed, among the directions. The graphics show this turbulence in different scales, with this we can see better these turbulence effects. The datum analysis was made with collected datum during 2007 year. This research still consists of demonstration of the datum that GRUMA and Lumet get straight from the meteorological towers. The graphics were made hereupon each independent variable, giving back an easily comprehension.
