The tropical cyclone frequency (TCF) is actually a certain integer, but the se exists uncertainty in the subjective and objective short-climatic forecasts, so the contiguous degree must be evaluated. In order to evaluate the accuracy of short-climatic forecasting on TCF,fistly three parameters,determine index(d) ,absolute error (E) and skill score (S),are defined comparatively with climatic probability forecast (CPF) which was regard as naught forecast. Then, the accura cy was evaluated of subjective forecast from 1988 to 1997. The results indicate : d, E and S of typhoon season are 0.3,1.7 and 0.06; d, E and S o f July are 0.9, 0.8 and 0.06; d?E and S of August are 0.7,0.75 and 0.13; d, E and S of September are 0.65,0.9 and 0.01, respectively.

热带气旋频数的实况是一确定的整数 ,而预测仍具一定的不确定性 ,其实质是一区间 ,即待评估的问题是预测区间与一确定整数的接近程度。针对待评估对象的这种特征 ,定义了d指数、绝对误差 (E)和技巧水平 (S) 3个评估参数 ,分别从趋势预测、定量预测、相对于气候概率预测的技巧等方面客观地标度待评估方法的预测性能 ,并对“九五”攻关前 1 0年( 1 988~ 1 997年 )的业务预测性能进行了再评估 :对 7月TCF预测的d指数和E分别为 0 .9和 0 .8个、相对于气候概率 (即无技巧 )预测的技巧水平为 - 0 .0 6;8月的d、E、S分别为0 .7、0 .75个和 0 .1 3;9月的d、E、S分别为 0 .65、0 .9个和 0 .0 1 ;台汛期的d、E、S分别为0 .3、1 .7个和 0 .0 6;全年的d、E、S分别为 0 .3、2 .2个和 0 .0 7。

>=The correlation coefficient between the tropical cyclone frequency and the geopotential height of 500hPa, sea-surface temperature (SST) of Pacific Ocean is calculated . By analyzing the statistical characteristics of those highly significant regions, we investigated the synoptic climatologically significance and the physical characteristics. Several high correlated factors selected and combined were used to construct active binomial forecast equations to forecast the yearly and monthly frequency of tropical cyclones of the West Pacific Ocean , South China Sea , that landed in China and Guangdong Province. The results show this forecast model has high fitting ability and performs well in the operational forecast.

使用前期北半球500HPA高度场格点资料、海温场(SST)格点资料,计算与后期热带气旋(TC)发生频数的相关系数,分析两个相关场显著相关区的统计特征,进一步分析其天气气候学意义和物理意义。选取若干相关系数高的格点,组成组合因子,建立动态的二项式曲线预报方程,制作西北太平洋、南海及登陆我国、登陆广东的热带气旋的年、月频数的预报。预报试验和检验表明,动态的二项式曲线预报模型,有较高的拟合能力,在业务应用中有较好的效果。
