Bosed on meteorological data in February and March from 1951 to 1990 at the forty-eight stations in South China,climatic features of spring cool damage are discussed in detail and some facts as follows.1 The more southward in South China,the more concentration toward February with respect to occurrence frequencies of spring lOw temperature process with cool damage. Its damage extent becomes heavier with increasing of latitudes and height above sea level.2 The interannual fluctuations of beginning and ending date of spring cool damage are great with a range of 30 days and 50-60 days,respectively.3 The dominating pattern is moist-cool for spring cool damage and it is mixed pattern as well as dry-cool pattern in turn.4 The peak values of pentad frequency of spring cool damage show a quasi-two weeks oscillation. The strong cool damage has quasi-three to four years cycle.
