The Anomalous Thermal and Wind Patterns during Early Summer Season of 1979 over the Afro-Asian Region in Relation to the Large-Scale Performance of the Monsoon over India

摘要

Anomalous features in the upper tropospheric temperature (cold anomaly) and wind field (westerly anomaly) over the Asian region during the early summer months of May and June in the Monex year of 1979 were found to persist in July and August. Surface pressure over India during the monsoon season of 1979 were also observed to be above normal. Abnormality was also found in the tracks of the monsoon depressions of the season.
