THE CORRELATION BETWEEN SPORADIC E-LAYERSAND SOLAR ACTIVITY

ZUO XIAO-MINWAN WEI-XING(Wuhan Institute of Physics and Mathematics,Chinese Academy of Sciences,Wuhan 430071,China)  
In this paper studies the correlation between solar activity and the intensity of sporadic E-layers by analyzing the global network data of critical frequency of E_S-layer during three solar cycles (1957\_1990). It is obtained that the yearly average of f_0E_S is correlated with solar activity in daytime,and anti-correlated at night. Meanwhile,the occurrence of sporadic E-layers has a positive correlation with solar activity in daytime and negative at nighttime. Detailed analysis shows that the discovered strong positive correlation of f_0E_S with solar activity in daytime is mainly caused by the contribution of regulat E-layers which are deeply controlled by solar activity. When eliminating the contribution of regular E-layers,the intensity of sporadic E-layer is slightly positively correlated with the yearly averaged sunspots number in daytime and negatively correlated at night. The correlation coefficient has a regular diurnal or semi-diurnal variation pattern.
