Precipitation and temperature trends in Kayseri
Abstract: Turkey is one of the sensitive regions to climate variation in the World. In this study, trends in precipitation and temperature at annual, seasonal and monthly time scales for the periods of 1960-2005 were examined for the Kayseri which is located in the Interior Anatolian region of Turkey. Non-parametric tests (such as Mann- ssion, cumulative deviation curve techniques were used to determine climatic trends. The results showed that there is no negative or positive statistically significant trend in the study area, despite of slight precipitation decrease in summer for the period of 1960-2005. In contrast, slight precipitation increases (which are not statistically significant) for winter, spring and autumn were determined. Temperature data showed slight increase annually even though results are not statistically significant during the study period. On the other hand, results of temperature trend analyses represent statistically significant trend for the moths of August and September at 90% confidence level.
Key words: Climate variation, precipitation, Mann-Kendall, trend, Kayseri
