Gökçeada'da ısı ve momentum akılarının etüdü

The growing interest in the interaction between the atmosphere and the underlying surface is driven by the realization that the surface fluxes of momentum, heat, and moisture determine to an important extent the steady state of the atmosphere. The purpose of this thesis is to analysis the surface fluxes at Gökçeada. In this study the data gared at 2 and 10 m meteorological most of Gökçeada (40° 11 N, 25° 54 E) in the center part and coastal part of island (Uğurlu) are analyzed. The wind, temperature and relative humidity measurements at Maslak (I.T.U) observation park are also taken in to account for calibration and test analysis. The surface fluxes of momentum, sensible heat and latent heat are calculated by using the atmospheric surface layer model based on M-O similarity theory (Beliaars and Holtslag ;1990). To define roughness height 12 sectors are consider at all three station. Momentum fluxes observed at the Uğurlu is 1.4 times grater than central part of Gökçeada, where is considered a rural part of island. 1.2 times grater latent heat fluxes are observed at Uğurlu. The maximum upward sensible heat flux is observed in central part but the maximum downward sensible heat fluxes are observed in Uğurlu. In this thesis, at two different places, one is urban and the other rural, the range and time variation of fluxes are studied. These result would also apply on the fields of "air-pollution modeling", "hydrology" and "wind energy". Only the limitation is data recorded in autumn, and the results encode us for further studies.
