摘要：

研究了2005-2011年西北太平洋六对双台风个例，根据其路径特征将其分为三类：双台风同时转向；双台风一前一后移动；东台风转向、西台风原地打转或停滞不前等异常路径.利用WRF （Weather Research and Forecasting Model，V3.5.1）模式及其伴随模式分别计算了各个台风的基于伴随模式的引导气流敏感性（Adjoint?Derived Sensitivity Steering Vector，ADSSV），在此基础上分析了不同移动类型的双台风之间的相互影响和环境场对其影响的差异.研究结果表明：ADSSV在垂直方向上主要分布在850 hPa和500 hPa之间，不同台风引导气流敏感性极值的高度具有较明显的差异；不同双台风ADSSV的水平分布特征也有显著不同，有的双台风之间的相互影响非常明显，有的双台风则属于单向影响型，还有的双台风虽然满足双台风的定义，但它们相互之间并没有明显的相互作用.

关键词: 双台风, 引导气流, 伴随敏感性, 引导气流敏感性

Abstract:

Six binary typhoons occurred in the western North Pacific from 2005 to 2011 are identified and analyzed. According to the features of binary typhoons' tracks，three distinct track types are proposed. The WRF(Weather Research and Forecasting Model，V3.5.1) model and its adjoint model are employed to calculate the sensitivity of steering flow and explore the binary interaction and environmental impact on binary typhoons of each track type. The results show the sensitivity of steering flow vertically distributed mainly in the middle and lower layers and the vertical distribution of extreme values are largely different among different typhoons. Binary typhoons have significantly different horizontal distribution characteristics of adjoint?derived sensitivity: the interactions between binary typhoons of different samples are obvious，some are one?way influence type，and some samples satisfied the definition of binary typhoons，but there is no obvious interaction between them.

Key words: binary typhoons, steering flow, adjoint?derived sensitivity, adjoint?derived sensitivity steering vector
