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

于2022财政年度末，我们能够达到两份具高影响力的国际刊物的接受阶段（请参阅T2R2）（于2023财政年度正式接受）。这些论文的重点是改进城市化建模，以考虑铁路引起的城市增长，并调查城市化和全球气候变化对大型特大城市变暖的综合影响（23）。国内论文也被接受，我们看了日本各地的热舒适（UTCI）的趋势，从历史气象观测评估。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热带气象学和大气科学国际会议等国际会议上介绍了这些发现以及与区域气候中的地热引起的变暖有关的其他发现。这些会议是促进我们工作的一个渠道，并为继续研究提供更好的远见。研究所还应邀在印度尼西亚万隆举行的第二届地球科学与技术国际研讨会上作了题为"全球城市气候学"的主题演讲。我们还成功地将我们公开的全球人为热通量（AH4GUC）纳入了广泛使用的CESM 2（NCAR）。与一名本科生，我们发现AH4GUC对模拟的空气温度的影响是显着的全球。我们验证了效果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.
