Indian summer monsoon is important to study in relation with the air-sea interaction processes. Find later jet (FLJ) is a Low Level Jet observed at 850 mb by which the moisture is transported to the Indian sub-continent from the Indian Ocean. In this connection it is important to observe FLJ intensity variations over Arabian Sea. In this article authors attempted to examine the Intraseasonal variability of FLJ intensities for the period 1980-2012 in relation to Sea Surface Temperature anomalies (SSTA) over Arabian Sea during summer monsoon season. As El Nino and La Nina are affecting the summer monsoon rainfall, authors studied the variations in FLJ and SSTA and also evaluated the correlation between FLJ and SSTA during the above mentioned period. An apparent relationship is found between the intensity of FLJ and SSTA over Arabian Sea region. FLJ is increasing in July during an El Nino event and SSTA is higher positive anomalies.
