Abstract
The present paper seeks to examine spatial and temporal variability of changes in both warm and cold extreme temperatures. Additionally, it aims to determine the most extreme geographical areas in extreme temperatures based on climate data recorded during the period from 1961 to 2020. This paper analysed the annual data of extreme temperatures for 16 meteorological stations during 1961- 2020 across Libya over two climatic regions (coastal and inland) based on Mann–Kendall test. Time trend of the extreme of both maximum and minimum temperature will be analyses and the results from geographical analysis are will also be presented based on ArcMap. The results indicated that a significant increase in the coldest extreme (TNn) temperature are found in autumn and spring and winter at majority of stations. Temperature variability can be associated with variations in large-scale atmospheric patterns represented by Eastern Atlantic and the Western Mediterranean Oscillations.
