Title: Primary Study on the Relation Between Sea Surface Temperature and Cloud Liquid Water in Three Tropical Oceans
Abstract: The tropical Pacific,the tropical Indian Ocean and the tropical Atlantic are the most prominent areas in terms of Ocean Atmosphere interaction on earth.To probe into some features about the local Ocean Atmosphere interaction,new satellite data for the Sea Surface Temperature(SST) anomaly and Cloud Liquid Water(CLW) have been analysed statistically by correlation analysis in the three tropical oceans in this paper.It is discovered that the synchronous correlation coefficients of SST anomaly and CLW anomaly are always positive within 5 weeks of lead or lag time,which means there is a positive feedback mechanism between SST anomaly and CLW anomaly in the equatorial Pacific and Atlantic;When the SST anomaly leads the CLW anomaly by one week,the positive correlation coefficient is maximum,which means that the SST variation could lead the CLW variation in the west tropical Indian Ocean;Contrary to this,the synchronous correlation coefficient is negative in cold sea surfaces,such as the extra-equatorial southeast and northeast Pacific and extra-equatorial south Atlantic,where the CLW variation could lead to the SST variation.In the tropical northwest pacific,which is in the east of the Philippines,the CLW variation could also lead to the SST variation;In the east equatorial Indian Ocean,the SST increase(decrease) could lead to CLW increase(decrease) in some periods,and CLW increase(decrease) could also conduce to SST decrease(increase) in other periods.Those results will be useful for understanding tropical ocean-atmosphere interaction and improving the parameterization scheme of ocean-atmosphere interaction.
