摘要：
An attempt has been made to identify low level jet (LLJ) stream influence on Monsoon onset over Kerala (MOK) by considering the wind intensities at 850 hPa over AS (5-20 degrees N and 55-75 degrees E) during the period 1997-2012. The intensity of LLJ confirms an apparent increase after onset; however, rainfall over Kerala is not well correlated with LLJ intensities. During El Nino years, there is a significant positive relation between LLJ and consecutive rainfall after onset.
