Abstract :Due to the high proportion of arable land in the province of Konya and the seasonal variability in rainfall in this region, this study investigates the trend analysis of relative humidity and precipitation for the province of Konya. The Turkish State Meteorological Service provided the statistics on relative humidity and the amount of precipitation covering a 91-year span from 1929 to 2020. Mann Kendall Test and Sen’s Trend Slope Method were used at 95% confidence level to investigate the trend analysis of meteorological data of relative humidity and precipitation. In the lights of analysis, the values range from −0.087 to 0.121 for the months of January through December, with the majority of values being near 0 for Kendall’s tau, most p-values are larger than 0.05, and the values for Sen’s slope range from −0.087 to 0.121 for the monthly precipitation. Depending on the results, the values for Kendall\'s tau and Sen\'s slope are close to zero, and the p-values are high, indicating a lack of statistical significance in the trends for the average monthly precipitation. The range of values is −0.007 to −0.248 for Kendall’s tau, p-values are less than 0.05 in a few months (January, June, December), and 0.076 to 0.000 is the range of values Sen’s slope for average relative humidity. Sen\'s slope and the Mann-Kendall test indicate that there is a significant tendency toward a decreasing relative humidity for three months (January, June, and December) in terms of statistics but not for the other months for average relative humidity. It was suggested that when predicting climate change, scenarios and climate models that do not predict significant differences in Konya\'s relative humidity and precipitation could be considered as a guide.Keywords : Yağış, Bağıl Nem, Sen, Trend analizi, Mann-Kendall test
