摘要
本文利用青藏高原中部的唐古拉山口附近连续的气温、气压、湿度、风速、风向及太阳辐射资料,初步分析了该区域年内气候变化和日变化等特征:年平均气温为-6.0℃,最冷月为12月,最热月为7月,与高原西部比较,具有升湿快、降温慢的变化特点;降水多集中于6-8月,但相对湿度的年际变化无规律可循,湿度变化与热力作用关系密切;年平均风速为3.6m/s,且冬季风强、夏季风弱,上午风弱、午后风强,1月午后风速可达10.0m/s;太阳辐射年总量为7172.3MJ,5月最大,1月最小,反射率12月最大,7月最小。
According to the analysing the climatic datas on 105,station near Tanggula Mountain Pass in centre of Tibetan Plateau,shows its annal veriation and diurnal veriation of climaticfators.Some preliminary knowledge on climatic feature of this areas were got:The average annal temperature is–6.0℃.the minimum temperature occurs in December and the maxi-mum temperature in July,comparing with western part of Plateau,there are climatic feature in observated areas like temperature increasing fastly and decreasing slowly.The preciptation mainly take place from June to August,but the relative humidity changes out of law.humidi-ty changes related well with thermodynamic reaction.Meanly annal windspeed is 3.6 m/s,there is strong wind in winter and weak wind in summer,also strong wind afternoon and weak wind in morning,the wind speed at afternoon in January could being as 10.0 m/s.The annal total global radiation should be 7172.3 MJ,the maximum albedo were happen in De-cember and minimum albedo in July.
