In order to understand phytoplankton ecology in the Gulf of Yeong-il, climatic factors such as air-temperature, solar-radiation, evaporation, direction and strength of winds, and precipitation are studied from January 1982 to December 1985. Annual average of air-temperature during the four-years period is about 13.6C . ranging from lfC (January) to 26.5"C (August). The maximum value of solarradiation is measured in spring (520 M] m 'in May), the minimun : in winter (62 MJm 2 in December, January or February), and the total annual value : about 4987 MJm -2. Annual average of evaporation is about 1200mm (Maximum : 169 in May ; Minimun : 56 in February), close to precipitation (about 1050mm). Annual average of strength of "North Winds" (350°- 90°) is about 550m • sec 1 for 156 frequences during 191 days, "West Winds" Cl70°-340°) : 511m •sec 1 f9r 185 frequences during 148 days, and "South Winds" ( 100° -160°) : about 61 m• sec 1 for 25 frequences during 24 days. "N" winds is about 30% more violant than "W" winds, but both winds are influential in terms of water movements in the Gulf.
