5月和10～11月是孟加拉湾风暴活动的两个"峰值"期, 风暴对西南水汽输送有重要影响, 本文利用2001～2010年10年的JTWC(Joint Typhoon Warning Centre)风暴资料和NCEP(National Centers for Environmental Prediction)/NCAR(National Center for Atmospheric Research)1°×1°再分析资料, 研究风暴"双峰"期对西南水汽输送的贡献, 结果表明:风暴水汽向北输送最强, 其次是向东输送, 其它方向的输送较弱;在风暴中心区域及西南水汽通道, 各层和整层的 通量均大于气候平均值, 风暴的西南水汽输送特征显著;两个"峰值"期风暴的经向水汽输送比纬向几乎大一倍, 5月"峰值"期孟加拉湾风暴在西南方向的实际水汽输送总量约是10～11月的2倍, 孟加拉湾风暴前"峰值"期(5月)对水汽输送的影响大于后"峰值"期(10～11月), 孟加拉湾风暴是5月西南水汽输送的主要系统之一
