中文摘要: 利用非线性逐步回归方法作台风活动趋势的预报。在回归方程中考虑了预报因子与预报量之间的非线性关系,回归方程中选入的非线性因子具有较高的相关显著性,对1995~1997 年台风预测试验表明:非线性因子在预报中起着及其重要的作用,取得了较好的预报效果。
Abstract:The nonlinear stepwise regression method is used to make typhoon activity tendency forecast.Predictors chosen in the nonlinear regression equations are associated with very high correlation significance level.By considering nonlinear relationships between predictors and predictands in regression equations,better forecast results were gained in the typhoon activity forecast tests in 1995—1997.
