Climate change studies of the high mountain areas central Himalayan region are mostly represented by meteorological stations lower elevation. Therefore, to validate climatic linkages, daily observational climate data from five automated weather (AWS) at elevations ranging 2660 m 5600 on southern slope Mt. Everest were examined. Despite variations in means and distribution daily, 5-day, 10-day, monthly temperature precipitation between located a higher elevation their corresponding elevation, records different highly correlated. In contrast, shows comparatively weaker correlation. The slopes regression model (0.82–1.13) with (R2>0.74) for altitude (5050 m) throughout year, 0.83–1.12 (R2>0.68) except late monsoon season station 4260 5050 asl indicated similar variability those stations. Similarly, Namche (3570 changes 0.81–1.32°C per degree Lukla (2660 m), season. However, inconsistent variation was observed large altitudinal difference (2940 Kala Patthar (5600 m). general, can be used quantitatively assess information Everest. corrections necessary when absolute values factors considered, especially snow cover snow-free areas. This study will beneficial understanding high-altitude impact studies.
