摘要 利用GMS高精度遥感海表温度(SST)反演资料、外逸长波辐射(OLR)反演资料和西北太平洋热带气旋(TC)源地及频数数据,分析了GMS-SST、赤道辐合带(ITCZ)、TC源地及频数的时空分布特征。研究发现:TC源地、发生频数以及强度的时空分布和变化均具有趋暖性。GMS-SST大于等于28℃的阈值条件为西北太平洋TC发生和维持的必要条件。并且存在10°N高频收缩轴,其与由GMS-SST大于等于28℃所定义的西北太平洋暖水区,GMS-OLR小于等于240 W.m-2定义的ITCZ的时空分布及变化有很好的相关性,即存在TC高频源地—GMS-SST暖水区—ITCZ三者间的匹配相关。 By using the high resolution SST ( Sea Surface Temperature ), OLR ( Outgoing Longwave Radiation) data measured by GMS( Geostationary Meteorological Satellite) and the tropical cyclone (TC) frequencies with their initiating locations over the NWP ( North-West Pacific ) ocean, the characteristics of the temporal and spatial distribution of SST (Sea Surface Temperature ), ITCZ (Intertropical Convergence Zone ) and TC are analyzed in details. It was found that the frequencies, the intensities and the distribu- tions of TC exist an obvious toward-wanning uptrend. Furthermore, the necessary condition of GMS-SST larger than and equal to 28 ℃ is proposed as a critical ocean-surface temperature to the arising and maintaining of TC. Also there exists a contracting axis for TC high frequencies around 10°N. Such contracting axis indeed suggests an unique synchronous-matching mechanism with the warm-water region, defined by GMS-SST larger than and equal to 28 ℃, and the ITCZ, defined by OLR less than and equal to 240 W · m^-2. That is to say,the strong correlationship exists among the three.
