Abstract

Upper tropospheric circulation associated with the development of a western disturbance, which was active over India and Pakistan from 28 to 31, December 1960 has been studied with the help of the Asian charts. It was observed that between 26th and 28th a meridional type circulation developed at 300-mb level in the Middle-East and the South-Russian Region. As a result, the upper air trough in the westerlies extended deep into the north, Arabian Sea and a strong northwesterly Jet developed upstream of this trough by the 28th. It was on this day that a feeble western disturbance aolng Makran coast intensified. On the 29th the meridional circulation at 360-mb level was destroyed. Probable causes of these developments in the upper air as well as at the surface have been discussed.
