Superimposition of upper divergence on pre-existing lower convergence is a well known fact for rapid intensification of the low level system. An attempt is made to show how rapid and intense developments of some of the small or meso scale systems in the Indian summer monsoon field are actually associated with the appearance of small cored upper anticyclonic spirals fractionally imposed on the low level systems, the upper anticyclonic spiral, thereby, serving as a forerunner for such typical meso or small scale accentuations.
