The Changing Trend of Precipitation Patterns along the Yellow Sea and Bohai Sea Coasts and Its Correlation with Global Warming

Abstract

Anthropogenic climate change is exerting a strong influence on the water cycle, which presents a massive challenge to ecosystem and socio-economic stability, with densely populated regions especially susceptible to it. Although a lot of research has been done on the precipitation trends of the East Asian area, the relationship between early monsoon-affected Yellow and Bohai Sea coats with global warming and the trends of precipitation is still uncontrolled. To address this problem, this study compared the pattern of precipitation of the Liaodong Peninsula between 1982 and 2024. The analysis employed NASA POWER gridded precipitation data and the GISTEMP data of global mean temperature tapering data. NASA’s Goddard Institute of Space Studies manipulated such data and utilized two-sample T-tests, linear quotients, and Pearson correlations to examine monthly distinctions, extreme precipitation indexes, and how they follow global warming. Findings indicated that there were great changes in the way precipitation is distributed per month and more dramatic events of precipitation. Also, these extraordinary occurrences were positively associated with the warming of the world’s climate. This work demonstrates that global warming is increasing the intensity and concentration of summer monsoons in this area, and an increase in the odds of extreme rainfall could be valuable in localized information on climate adaptation and mitigation measures.
