Correlation is seen in increased cloud coverage when nearing the equator. The inverse relationship is also true that the poles would have less cloud coverage. Cloud coverage was much greater in the oceans than on land. According to our charts, the greatest cloud coverage occurs in the Atlantic Ocean adjoining South America and the southern part of Africa. Cloud differences can also be attr ibuted to differences in the convection of land and water.
Oceans tend to have constant evaporation and clouds formed tended to be thinner.
Most of the cloud formation of the oceans affect the weather systems of the landmasses especially in determining areas of heavy precipitation, winds, etc. Our graphs also show that in cooler parts of the year, we would experience noreasters and mid-latitude cyclones. In the 1986 series of data, we see special phenomenon called El Nino. It affected the cloud coverage, and rose the average sea temperature. In 1987, La Nina decreased the annual mean temperatures of the sea.
