Spatial variation of climatic comfort levels in Al-Jabal Al-Akhdar region - Northeast Libya

Abstract

This study highlights on the impact of climate fluctuations on human comfort to find out the temporal and spatial variation of physiological comfort of humans in the Al-Jabal Al-Akhdar Region. Some physiological comfort was used based on the seasonal averages of temperature and humidity for the period from (1985 to 2019). Moreover, the spatial analysis method in the GIS was used to know the spatial variation of comfort levels. The results indicated that the rates of thermal gain during the day are prevail in the summer only, where the highest values reached (122) k/H in Al-Makhili, while at the night period, it is dominated by thermal loss in all seasons, especially in the winter season as a result of low temperatures, where the highest thermal loss values reach (-471.4) k/H in Al-Qiqab. Autumn is the ideal season in terms of climatic comfort, while winter is characterized by feeling of relatively cold discomfort, while the feeling is relatively hot comfort in summer, and relatively cool in spring.
