Characteristic features of temporal and spatial variations of the flow fields at 850 hPa level over the areas dominated by the East Asian and Indian monsoons during the summer months from May to October, 1984 are analysed by means of synoptic-statistical method. By combining the results obtained in an earlier paper[1], preliminary knowledge of the discrepancy and relation of the lower atmospheric circulations between the two monsoon regions in the summer season is attained.
