The relationship between red tide disasters in the coastal area of Fujian Province and meteorological conditions is studied，and the circulation patterns for forecasting red tide disasters meteorologically is summed up. The red tide disaster data from 2001 to 2008 in the coastal area of Fujian Province and meteorological data of the corresponding period are used to seek the meteorological factors correlated with red tide disasters，so to analyze meteorological situations on the surface and at different levels during red tide disasters and to study the relationship between Southern Oscillation Index and occurrence of red tide disasters. Results show that meteorological factors such as wind，temperature，humidity， sunshine, and pressure in the coast area of Fujian are correlated well with red tide disasters， but the major factors vary in the different sea areas. The circulation situation at 850 hPa and on surface can better reflect the meteorological background during red tide disasters. Results also show good corresponding relation, with the correlation coefficient being -0.745, between Southern Oscillation index and the occurrence days of red tides next year.
