| 摘 要： | 探讨了利用气旋风场分布的经验模型估算热带气旋尺度(8级大风圈半径)的方法.用美国联合台风警报中心整编的2001年西北太平洋热带气旋的“最佳尺度”资料,确定了各模型的经验常数,并计算了各模型的估算精度.结果表明,“VBogus”模型能获得热带气旋(Tropical Cyclone,简称TC)尺度的较好估算.基于“VBogus”模型,通过拟合热带气旋尺度的非对称分布,构造了能描述热带气旋非对称风场的"修正VBogus"模型,并估算了该模型中各参数在不同季节和不同地理区域的取值,为热带气旋尺度变化和非对称结构机制等问题的研究和应用提供新依据.

| Abstract: | This paper investigates the method of using the experiential model of tropical cyclone's wind distribution to estimate the tropical cyclone size(the radius of gale cycle).The "best size"data of the Northwest Pacific of 2001 compiled by Joint Typhoon Warning Center(JTWC)is used to determine the empirical constants of different models, and compute their estimating precisions.The results show that the "VBogus"model is better than other experiential models.Moreover,based on the "VBogus"model,we construct the wind size,estimate the value of characteristic parameters in this model in different seasons and geographical regions,which provide new evidence for the study and application of tropical cyclone size and asymmetric structure. |
