Abstract

ABSTRACT

In this study, Mann Kendall, Spearman rho and Innovative Sen Method were used to determine the monthly and annual trends of temperature, precipitation, humidity and pressure parameters of four meteorological observation stations located in Giresun, Trabzon, Rize and Hopa. In addition, Standard Precipitation Index, Percentage of Normal Index and De Martonne Aridity Index were used for meteorological drought analysis of these four stations.

As a result of the analysis, an increasing trend in temperature values was determined. Irregularities in precipitation, humidity and pressure are observed on monthly basis. An increasing trend is observed in annual total precipitation values at Giresun and Hopa stations, however, a decreasing trend is observed at other stations. There was a decreasing trend in average humidity values and an increasing trend in maximum humidity values. These results and meteorological drought analysis results prove these irregularities. Sea surface temperature data of the ERA5 of Copernicus satellites and actual measurements were compared and the relationship between them was examined. When the data were compared, a high correlation was found in Giresun and Hopa. Also sea surface temperatures are examined, an increasing trend is observed in both data sets.
