The SST or sea surface temperature refers to the temperature of the water close to the surface of the ocean. Sea surface temperature influences the behavior of the atmosphere of the Earth, so their initialization into the atmospheric model is essential. While SST plays a vital role for tropical cyclogenesis, it is also essential in predicting the formation of sea breezes and sea fog.
The changes in SST reflects the overall trend of warming of the climatic system, and in turn, affects the climate and weather patterns globally. If the SST is too warm, the humidity upsurges and the greenhouse effect enhances.
