THE TIME-VARIATION OF ATMOSPHERIC TRANSPARENT COEFFICIENTS IN CHINA

Fang Xianjin Weng Duming (Nanjing Institute of meteorology)Qian Weihong (Metcorological Bureau of Jiangsu Province)  
In this paper the time-variation of the atmospheric transparent coefficient (P2) and the transparent coefficients for aerosol and water vapour (pd and Pw) have been calculated and discussed. It has been found here that P., Observed at China's plain station, in summer, dec-rease an average 6.7%, 5.7% and 6.0% by the volcanic eruptions of Agung, Fuego and St. Helens respectively. The longterm changing trends of Pi, Pj become monotonously lower with the effects of the urban air pollution. Coherences between P2 and the coal-used amounts for several big cities suth as Beijing, are very obvious. The annual variation of the corresponding relations between P2 for Lanzhou City and the amounts of dust floating in the air and the day number of smoky fog occurring and the number of inversion occurring are all good. Finally, the characters of the daily variation for P2 over China have been discussed.In this paper, the fluctuations of quasi-44-month, quasi-11-year, quasi-24-year and quasi-49-year periods of the earth rotational rate are found from the analysis of its data of the years 1820?983. The anomalies of Southern Oscillation (SO) index, the motions of the atmospheric centres of action, the variations of sea surface temperature in the eastern equatorial pacific and the changes of long-range weather can be related with the periodic fluctuations of the earth rotational rate. It has been found that SO index becomes weaker (stronger), active centres of atmosphere move northwest-ward (southeast-ward) and annual precipitations increase (decrease) in Africa arid region, while the long-range earth rotational rate (fluctuations of quasi-24-year and quasi-49-year) speeds up (slows down). It has been also found that sea surface temperature is lower (higher) in the eastern equatorial Pacific, while the short-range earth rotational rate (quasi-44-mouth)speeds up (slows down).
