| Abstract: | Based on the correlative analysis between Hubei early-rice annual bumper or poor harvest, SOI and atmopheric circulation, factors with strong influence upon the key periods of early-rice yield formation and of significant weather or biological meanings were found out. A prediction model of annual yield was also established. |

| Keywords: | early-rice annual yield SOI atmopheric circulation physical factors prediction model |
