The main purpose of this study is to define the small and large scale (local and synoptic) fluctuations on the meteorological parameters. Some meteorological data (pressure, wind velocity, precipitation, relative humidity and temperature) observed in these stations at the Northeastern BlackSea Region have been considered. Meteorological data for long term (19601990) and shortterm (19911994) have been analyzed in statistically. Analysis of first to sixth order harmonic amplitudes and phases have been calculated by using the Fourier Transformation. The first and sixth order harmonic amplitudes and phases provide a useful source to understand the local and large scale effects on these parameters. As a result of this study the precipitation and relative humidity observed in Trabzon and Hopa are mostly effected by the synoptic circulations. The influence of micro scale phenomena on wind speed is similar at all stations. The phase angle can be used to determine the time of year the maximum or minimum of a given harmonic occurs. This paper is a pilot study for the climatological changing investigations in this region.<P>
