THE PRECIPITATION REGIME IN SHKODRA ECOSYSTEM: A CASE STUDY

Precipitation is an important element of climate. Its impact in the ecosystem is direct. Its assessment constitutes a necessity. For the evaluation of the precipitation regime and its tendencies in the region of Shkodra, there has been analyzed data for a period of over 35 years. These values are the contribution of meteorological control centers in Shkodra. For analysis of meteorological indicators were used mathematical methods of statistical analysis, regression equations, and mean deviation. The data processed with the Excel program and its graphical presentation, gives us the possibility of having a clear interpretation on local climate and its changes. The regression equation was: y =-0.894x + 181.5 with r = 0.368. This means that for every 5 years there is a variation of precipitation with about 4.5 mm per month. Analysis of the factual and theoretical results indicates significant differences. By analyzing the varying average we conclude on large margins. From analysis of data presented in the precipitation chart it results that the precipitation values are of cyclical character. These cycles of precipitation, with approximate values, are of the time periods between 1951-1961, 1962-1972, 1973-1983, 1984-1994 and 1995 onwards.
