The largest factor behind the decrease in yields in paddy rice fields in Saga Prefecture is salty wind damage, which has been caused in recent years by “the wind typhoons”; typhoon Nos. 17 and 19 in 1991, No.18 in 2004, and No.13 in 2006. The damage to paddy rice fields has been intensifying from typhoons striking Saga Prefecture directly, although when the damage year of 2006 is compared with that of 1990, for the Ariake sea coast municipality, a reduction is evident. Based on the analysis of the occurrence factor score relating to the amount of damage to paddy rice fields caused by salty wind, the dispersion degree of the salty wind was the key factor affecting the amount of damage, followed by the time of the typhoon striking, and subsequently the extent to which the adhering salinity was washed away via precipitation. This was considered to be the case because only the amount of damage by salty wind was used for the analysis of the response variable. Regarding methods to avoid and reduce the problem of salty wind damage, diversification of the planted varieties and varying the transplantation time, etc. can be considered practical means.
