Global-to-Regional Urban Climate Change Assessment and Modeling (GRUCCAM)

在2022财年末，我们完成了两篇高影响力国际出版物（请参考T2R2）的验收阶段（2023财年正式验收）。这两篇论文的重点是改进城市化模型，以考虑铁路引发的城市增长，以及调查城市化和全球气候变化对特大城市变暖的综合影响（23）。一篇国内论文也被接受，我们从历史气象观测中评估了整个日本的热舒适（UTCI）趋势。我们还在亚洲大洋洲地球科学学会（AOGS）第19届年会、美国地球物理联合会2022年秋季会议和第二届国际热带气象与大气科学会议等国际会议上提出了这些发现和与人为热引起的区域气候变暖有关的其他发现。这些会议是促进我们的工作和为持续研究提供更好的远见的途径。在印度尼西亚万隆举行的第二届国际地球科学与技术研讨会上，PI还应邀就“全球城市气候学”主题发表了主题演讲。我们还成功地将可公开获得的全球人为热通量（AH4GUC）纳入广泛使用的CESM2 （NCAR）。与一名本科生一起，我们发现AH4GUC对模拟气温的影响在全球范围内是显著的。我们验证了效果的强度与使用空调的默认设置相匹配。

In the end of fiscal year 2022, we were able to reach acceptance stage of two international publications of high impact (please refer to T2R2) (officially accepted in fiscal year 2023). The papers focused on the improvement of urbanization modelling to consider railway-induced urban growth and investigation of combined urbanization and global climate-change influence to warming in large megacities (23). A domestic paper was also accepted where we looked at trends of thermal comfort (UTCI) across the Japan, as evaluated from historical meteorological observations. We have also presented these and an additional finding related to anthropogenic-heat-induced warming in a regional climate in international conferences such as the Asia Oceania Geosciences Society (AOGS) 19th annual meeting, the American Geophysical Union Fall Meeting 2022, and the 2nd International Conference on Tropical Meteorology and Atmospheric Science. The conferences served as an avenue to promote our works and provide better foresight in continual research. The PI was also invited to give a keynote talk on the topic of "Global Urban Climatology" during the 2nd International Seminar on Earth Sciences and Technology, Bandung, Indonesia.We have also succeeded in incorporating our global anthropogenic heat flux (AH4GUC), that is publicly available, into the widely used CESM2 (NCAR). With an undergraduate student, we found that the effect of AH4GUC on the modelled air temperature is significant globally. We verified that the intensity of effect matches that of the default set-up that utilizes air-conditioning.
