Abstract:
The spatial and temporal analysis of Relative humidity is very important for climatic variability. Seasonal
and annual data for 8 meteorological stations in the Kurdistan region of Iraq (1992-2020) were analyzed to
determine the significant trends and magnitude of RH using the Mann-Kendall test and Sens slope with the
GIS interpolation method. The spatial analysis shows that the highest values were recorded at the Pirmam
station with values of (71.40%) and (52.91%) in the winter season and annual data respectively, while the
lowest value was recorded at Akre station of (19.21%) and (41.83%) in summer season and annual data
respectively. According to the temporal variations of RH, significant decreasing trends are found at Akre
station at the different confidence levels with the lowest value of (-0.996%/yr) at the 95% confidence level
during the winter season. However, in the Erbil, Chamchamal, and Sulaymaniyah stations, substantial
positive increasing trends were identified, Chamchamal station has the highest value of (0.780 %/yr) at the
95% confidence level in the winter season. The annual RH trends indicated that Akre, Duhok, Erbil,
Chamchamal and Sulaymaniyah revealed significant increasing and decreasing trends at different confidence
levels, Akre station has the maximum dropping trend with a value of (-0.858 %/yr), on the other hand, the
maximum rising RH trends of (0.500%/yr) detected at Chamchamal station. |
