CHAPTER ONE
INTRODUCTION
BACKGROUND TO STUDY
Sea surface temperature (SST) is the temperature of the sea surface representing the condition in the surface mixed layer underlying the ocean skin. It is a geophysical variable of importance to marine meteorological services, the world climate research programme and also other large and small-scale research programmes. Its distribution on local, regional, hemispheric or global scales are of interest to scientists for the study of variety of processes in the sea, coastal areas and in the atmosphere. These ranges from local air-sea interaction and their relationship to local weather which include rainfall, which is the considered in this study. Processes in the ocean often have thermal expression at the sea surface e.g. Mesoscale eddies and upwelling. The importance of SST cannot be overemphasized in the field of meteorology and water resources, it has diverse uses ranging from forecasting of weather such as development of showers, thunderstorm, fog and rainfall amount [1, 2, and 3].SST may also determine areas of fish catchment by fishing fleet.
