Abstract

Climate change impacts are perceived today as
being very noticeable; determination of precipitation, wind, flow, evaporation
and temperature trends has become essential for water resources and engineering
projects in management and planning. Nowadays there is a lot of studies have
been made in progress on global and regional climate changes in literature. In
this study, monthly, annual and seasonal trends in average temperature, total
precipitation, and average wind speed data calculated by Mann-Kendall, linear
trend and Sen’s trend tests. The gauge station is located in Samsun, which is
the largest city of the Turkey’s Black Sea region. The data sets are obtained
for the period 1980 to 2015. According to the results, at the levels of
significance of 5% and 10%, Mann-Kendall's statistical results were found to be
generally similar to those of trend analysis methods.
