pattern characterized by “north drought/south flooding” in eastern China. Luo et al. (2000) analyzed the direct insolation in four southern China urban areas to find that direct insolation has decreased by over 20% compared to that in the period from 1960 to 1980. In a general circulation model study, Menon et al. (2002) reported that the absorbing aerosols can significantly affect the atmospheric circulation and water cycle, and hence regional climate, via atmospheric heating that alters the

(Manuscript Received, October 19, 1945),ABSTRACTFrom records of insolation and from observations of cloudiness and cloud density obtained at Blue HillObservatory relations have been derived which give the amount of insolation, T, to be expected on theaverage with a given cloudiness, cloud density and solar air mass. These relations are of the formT = (a/m)e-bm where m = air mass (i.e. secant of zenith distance of the sun), e = base of natural logarithms,a and b are constants which depend on the cloudiness and

1. Introduction The global and annual mean insolation changes only moderately in response to changes in Earth’s orbit, but the associated geographic and seasonal redistribution of solar radiation on Earth may dramatically affect Earth’s climate ( Milankovitch 1941 ; Berger 1978 ; Laskar 1990 ; Laskar et al. 1993 ; Paillard 2001 ). The Milankovitch hypothesis ( Milankovitch 1941 ), which links changes in summer insolation at the high latitudes of the Northern Hemisphere to the glacial
