Abstract
    A two-box model has been used to assess the relative importance of various factors contributing to changes in the temperatures of the eastern English Channel and the Southern Bight of the North Sea. As part of the data input to the model, monthly means (1961-1976) of the surface fluxes into the region were estimated by means of bulk formulae. The results showed that surface heat fluxes were the most important factor contributing to temperature variability on seasonal and interannual time-scales; fluctuations of temperature outside the region and variation of the flow through the English Channel were considerably less important. The importance of surface heating in the English Channel to the heat budget of the Southern Bight is shown. Estimates of latent heat flux were reliable enough to examine only seasonal changes. The heat fluxes which had most effect on temperatures from year to year in each region were insolation in all seasons (i.e. cloud cover) and sensible heat flux in the winter. There was a downward trend in the lateral heat fluxes into the Southern Bight during the period.
