Abstract

This study investigated changes and trends in
mean annual and seasonal temperatures together with temperature anomalies in
the province of Nevşehir, Turkey for the period 1960-2016. Nevşehir is within
the Central Anatolia Region which is potentially sensitive to climate change
due to its semi-arid climate. Trends in temperature series were analysed using
Mann-Kendall and Gaussian statistical tests. Results show statistically significant
increases in mean annual and summer temperatures at 0.05% level. A significant
increasing trend in spring and autumn temperatures is weaker than summer
temperatures. In other words, a slight warming trend in all these three seasons
was detected. For winter temperatures, an increasing trend was also detected in
this period. The trends, both annually and in summer, are evident from 1994,
when the mean annual temperatures were above the long-term average. The warmest
year was 2010 and the coldest year was 1992.
