【摘要】 本文取用我国哈尔滨、乌鲁木齐、沈阳、银川、西宁、太原、北京、上海、汉口、赣州、成都、拉萨、昆明、南宁、海口等15个日射观测站1958—1963年逐日定时观测资料建立了晴天太阳辐射量计算式,再根据对应时期中,低云、中云及高云量各为10的实测太阳辐射量推求低云、中云及高云对太阳辐射能的减弱系数,并分析了它们的时空变化。更多还原

【Abstract】 Utilizing the data of solar radiation opserved at definite times everyday from 1958 to 1963 at 15 solar radiation stations in China and by two methods, i.e. by using eguationQo=IoSinhO/1+fmand the correlation curve of atmospheric optical mass m and cloudless solar radiation (at clear days) Qo, we calculated the atmospheric tur bidity parameter f. Choosing the solar radiations corresponding to low, middle and high clouds with the cloudines as 10, we obtained the attenuation coefficients of solar radiation CL. Cc and Cj by the following equationsCL= (Qo-QL) /QoCc= (Qo-Qc) /QoCh= (Qo-Qh) /QoBased on the calculated results we analyzed and compared the cloudless solar radiation and the effects of low, middle and high clouds on solar radiation attenuation in China.更多还原
