Markov Chain Analysis of Rainfall over East Asia: Unusual Frequency, Persistence, and Entropy in the Summer 2020 (authors: Yoon-Kyoung Lee, Hye-Sil Kim, Jung-Eun Kim, Yong-Sang Choi, and Changhyun Yoo) is a research article that quantifies summer rainfall variability by analyzing the frequency and persistence of East Asia’s record-breaking rainfall in 2020. The research found out that heavy rainfall during the summer of 2020 can be attributed to anomalously high frequency of rainfall in Central China and Japan and greater rainfall persistence over eastern China and Korea. It also found out that changes in the frequency of rainfalls can be attributed to the increasing frequency of precipitation in Central China, and such changes are related to the surface temperature of the Central and Northern Pacific Ocean and the tropical Indian Ocean.
“This research explains the characteristics of unprecedentedly long-continued heavy rainfall in the summer of 2020. We hope this article can broaden the understanding of the mechanism of heavy rainfalls in East Asia and improve the predictability of heavy rainfalls,” explained research professor Yoonkyoung Lee, the first author of the paper.
This research was supported by the National Research Foundation of Korea’s Priority Research Institute Program. Research Professor Jung-Eun Kim participated in this research as a co-author, and Professor Yong-Sang Choi from the Department of Climate and Energy Systems Engineering and Professor Changhyun Yoo from the Center for Climate/Environment Change Prediction Research, as corresponding authors.
