Simulation of Water Vapor Transport Paths before and after Increased Rainstorms from Tropical Storm Bilis (0604)

  • 摘要: 采用水平分辨率1°×1°的NCEP 再分析资料、1°×1°的NCEP GDAS资料和2.5°×2.5°的NOAA大气环流资料, 结合NOAA HYSPLIT v4.8轨迹模式对0604号热带风暴“Bilis”整个生命史的水汽输送特征进行模拟分析, 并分析了“Bilis”暴雨增幅前和增幅后的水汽输送轨迹及不同来源的水汽贡献。结果表明, “Bilis”整个活动过程中主要有四支水汽输送通道, 分别是源自索马里、孟加拉湾、120°E 越赤道气流和东太平洋的水汽, 其中源自索马里和孟加拉湾的西南水汽输送(偏南水汽通道)占主导地位, 120°E 越赤道气流和东太平洋的水汽是西南水汽随着“Bilis”环流逆时针旋转, 自环流中心东北侧进入雨区(东北水汽通道), 是低压环流与偏南风相互作用的结果。其中, 偏南通道水汽大部分输送到850 hPa以下的低层, 自环流北侧输入的水汽则主要输送到暴雨区上空850 hPa以上。对比暴雨增幅前后各通道的水汽贡献率发现, 孟加拉湾西南气流输送的低纬水汽对此次暴雨增幅的形成、发展起重要作用。
