摘要：

The data on global irradiation incident on a horizontal surface in Port Harcourt during the 13-year period 1977-1989 are analyzed and shown to vary with the climatic changes of the year. The range of variation is found to be greatest in August. Based on the calculated average monthly clearness index values only five seasonal patterns are identified for Port Harcourt. The percentage of days with duration of sunshine less than 1.5 h is 28.3% while that greater than 9 h is 4.3%. The Angstrom type of regression model relating total global irradiation to sunshine duration has been found to be reasonably adequate only if long-term average monthly values are used.
