Typhoons are one of the most destructive weather systems with potentially serious impacts on human life, economics, social systems, and the environment. In particular, typhoons Jebi (2018), Faxai (2019), and Hagibis (2019), which made landfall in Japan, caused serious natural disasters in various areas of Japan and resulted in the record-breaking amount of insurance claims paid due to strong winds, torrential rainfalls, high waves, and storm surge. It is of great scientific interest that the causes and processes are clarified particularly on strong winds of Jebi and Faxai and heavy rainfall of Hagibis.
Regarding the prediction of typhoon intensity in 2018-2019, rapid intensification and weakening of typhoons remain challenging scientific topics. The interactions between typhoon Trami (2018) and the ocean and between typhoon Jongdari (2018) and the upper-tropospheric cold-core low are interesting topics in understanding the effect on the typhoon track predictions. Furthermore, the effect of global warming on these meteorological events in the future are also topics of great interest in addition to the effect on climatological typhoon activity in the western North Pacific.
In this special edition jointly coordinated with Journal of the Meteorological Society of Japan, we publish papers on all aspects of typhoons in 2018-2019, such as formation, movement, intensification, weakening, structure change, strong wind, heavy rainfall, high wave, storm surge, and the interaction with terrain, ocean, or midlatitude systems. We also publish papers on studies on the linkage between typhoons and climate processes that include both natural and anthropogenic origin and on the effect of global warming on meteorological events associated with typhoons in 2018-2019.

社论

台风是最具破坏性的天气系统之一，可能对人类生活，经济，社会系统和环境造成严重影响。特别是在日本登陆的台风Jebi（2018），Faxai（2019）和Hagibis（2019），在日本各个地区造成了严重的自然灾害，由于支付能力过强而导致的保险理赔额创纪录风，暴雨，大浪和风暴潮。具有极大的科学兴趣，尤其是在Jebi和Faxai的强风和Hagibis的强降雨时弄清了原因和过程。
关于2018-2019年台风强度的预测，台风的快速增强和减弱仍然是具有挑战性的科学课题。台风特拉米（2018）与海洋之间的相互作用以及台风钟达里（2018）与对流层高空低气压之间的相互作用是理解对台风径迹预报影响的有趣话题。此外，全球变暖对未来这些气象事件的影响，除了对北太平洋西部的气候台风活动的影响外，也引起人们极大的兴趣。
在与日本气象学会杂志共同协办的特别版中，我们就2018-2019年台风的各个方面发表论文，例如形成，移动，加剧，减弱，结构变化，强风，暴雨，高浪，风暴潮以及与地形，海洋或中纬度系统的相互作用。我们还将发表有关台风与气候过程之间联系的研究论文，其中包括自然和人为起源，以及全球变暖对2018-2019年与台风有关的气象事件的影响。
