单个值分解( SVD )分析被执行在热带气旋( TC )揭示在磁道的 interannual 变化和西方的向北和平的热带气旋( WNPTC )的紧张之间的关系活跃季节( JulyNovember )和全球网络 airsea 热流动( Q 网络)在前面的季节( AprilJune )。为这个目的,热带气旋轨道和紧张功能(TIF ) 被积累的气旋精力(王牌) 的联合定义索引和气旋轨道密度工作。 SVD 分析表明第一个模式为在在热带中央太平洋和西方的诺思太平洋( WNP ) TIF 的增加的活动的向上的热流动之间的积极关联负责,为在在北方印度洋和 WNPTC 的向东北的轨道移动的向上的热流动之间的积极关联的第二个模式和为在在中间纬度的中央太平洋和 WNP TC 的西北排水量的向上的热流动之间的否定关联的第三个模式这建议在一些关键区域的 Q 网异例在 WNP TC 活动有实质的遥远的影响。
A singular value decomposition (SVD) analysis is carried out to reveal the relationship between the interannual variation of track and intensity of the western North Pacific tropical cyclones (WNPTCs) in the tropical cyclone (TC) active season (July–November) and the global net air-sea heat flux (Q net ) in the preceding season (April–June). For this purpose, a tropical cyclone track and intensity function (TIF) is defined by a combination of accumulated cyclone energy (ACE) index and a cyclone track density function. The SVD analysis reveals that the first mode is responsible for the positive correlation between the upward heat flux in the tropical central Pacific and the increased activity of western North Pacific (WNP) TIF, the second mode for the positive correlation between the upward heat flux in the North Indian Ocean and the northeastward track shift of WNPTCs and the third mode for the negative correlation between the upward heat flux in mid-latitude central Pacific and the northwest displacement of the WNP TC-active center. This suggests that Q net anomalies in some key regions have a substantial remote impact on the WNP TC activity.
