Abstract

During 1979, the onset of monsoon over India was delayed by about 10 days baffling all scientists engaged in Monex-1979. In this paper, we present the possible causes of this delay based on the influence of the extra-tropical blocking highs, as revealed by the 5-day mean contour charts. The blocking highs prevailed over the Caspian Sea-Aral Sea area during May 1979 in two spells, one starting from last week of April and the other from third week of May extending upto first week of June 1979. Strong meridional flow was observed from east of the Caspian Sea to Afghanistan, Pakistan and the northwestern parts of India.
