温暖的北印度洋(NIO ) 海表面温度(SST ) ,与 El Ni 联系了 ? o/Southern 摆动(ENSO ) 和印度洋偶极子(IOD ) 模式,每月用国际全面海洋空气数据集合(ICOADS ) 被调查为时期 1979-2010 的数据。统计分析被用来从 ENSO 和 IOD 识别各自的贡献。结果显示在 9 月 11 月温暖的第一 NIO SST 与一个 IOD 事件被联系,当在跟随 ENSO 的成熟阶段的春天夏天温暖的第二 NIO SST 与一个 ENSO 事件被联系时。在 IOD 与 ENSO 共同发生的一年, NIO SST 温暖两次,在开发年和腐烂年的 ENSO 升起。短波放射和潜伏的热流动贡献 NIO SST 变化。在短波放射的变化由于在阴沉的变化。cloud-SST 反馈在温暖的 NIO SST 起一个重要作用。潜伏的热流动与在 monsoonal 风中的变化有关。在温暖的第一 NIO, SST 异例主要由于在潜伏的热流动的变化。在温暖的第二 NIO,两个因素是重要的。
The Northern Indian Ocean (NIO) sea surface temperature (SST) warming, associated with the E1 Nifio/Southern Oscillations (ENSO) and the Indian Ocean Dipole (IOD) mode, is investigated using the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) monthly data for the period 1979-2010. Statistical analy- ses are used to identify respective contribution from ENSO and IOD. The results indicate that the first NIO SST warming in September-November is associated with an IOD event, while the second NIO SST warming in spring-summer following the mature phase of ENSO is associated with an ENSO event. In the year that IOD co-occurred with ENSO, NIO SST warms twice, rising in the ENSO developing year and decay year. Both short- wave radiation and latent heat flux contribute to the NIO SST variation. The change in shortwave radiation is due to the change in cloudiness. A cloud-SST feedback plays an important role in NIO SST warming. The latent heat flux is related to the change in monsoonal wind. In the first NIO warming, the SST anomaly is mainly due to the change in the latent heat flux. In the second NIO warming, both factors are important.
