Summary
The variation of Arctic cloud cover in time and space during the summers of 1979, 1977 and part of 1978 was charted from satellite imagery in 3 to 7 day intervals. Three classes of cloud thickness were separately mapped. Confirming the finding of the earlier report dealing with the 1979 data, the optically thick clouds were found to be considerably less common than expected from earlier analyses of drifting station reports. The proportion of thick cloud increased in connection with low pressure systems advecting continental air masses over the Arctic Basin. The data available to date indicate that the thickest cloud cover over the central Arctic was observed in August. Throughout spring and summer of the analysed years, clear sky episodes all over the Arctic Basin lasted long enough to significantly affect the surface radiation balance and the dissipation of snow and ice cover. Our results indicate that general circulation models require realistic representation of poleward advection of continental air masses and of the conditions accompanying snow and ice melt. 16 references.
