Temporal and Spatial Trends of Precipitation and Mutation in Guangdong Province over the Past 60 Years by XU Chengyi

“…Based on the Mann-Kendall test,linear regression analysis,and sliding t-test,this study analyzes the daily precipitation data from 32 meteorological stations in Guangdong Province from 1960 to 2019.The results show that except for Guangzhou and Zengcheng in the Pearl River Delta region,which exhibit a significant increasing trend in annual precipitation,there is no significant increasing trend in annual precipitation in other regions of Guangdong Province.The spatial distribution of average annual precipitation shows that the Pearl River Delta and its adjacent areas are the areas with the highest precipitation,which decreases gradually towards the surrounding areas.In the analysis of annual precipitation mutations,eight meteorological stations are found to have different numbers of mutation points in different years.Among these,only the Pearl River Delta region shows an increasing mutation in annual precipitation in 1972.The research results can provide a reference for the management of water resources and flood prevention strategies in Guangdong Province to cope with climate change.…”

Research Progress and Prospect of Extreme Water Increase by Storm Surge in Estuaries — A Case Study of Guangdong-Hong Kong-Macao Greater Bay Area by LIU Yuexuan, LI Huijing, LI Lanbin, LIU Xiaojian

“…Significant increases in water and extreme tide levels caused by typhoon storm surges are the primary threat to flood safety in estuarine areas,and are also the main cause of major natural disaster losses in the Guangdong-Hong Kong-Macao Greater Bay Area in recent years.This paper reveals the evolution patterns of water increase in storm surges over the years and introduces corresponding research methods.Meanwhile,it systematically reviews research achievements on the formation mechanism of extreme tide levels in storm surges from both foreign and domestic perspectives.Combined calculation models of extreme tide levels formed by astronomical tides and storm surges in China and abroad are also summarized,with a focus on achievements in dynamic mechanisms during extreme water increase in storm surges.Additionally,a two-dimensional nested mathematical model of storm surges in the South China Sea and the Pearl River Estuary is built,and the most unfavorable typhoon intensity and path are designed.The maximum water increase distribution in the Guangdong-Hong Kong-Macao Greater Bay Area is preliminarily simulated and obtained.Finally,it is urgent to put forward a set of safe,concise,and applicable formula for calculating the extreme tide levels of storm surges as soon as possible based on the understanding of the physical mechanism of the interaction between astronomical tides and storm surges.…”

Interannual Variations of Upwelling in the East Coastof Guangdong and Its Correlation with Fisheries by WEN Hao, HONG Bo

“…Based on thedata of temperature, chlorophyll concentration and wind field from 2002 to 2016, marine catches inGuangdong Province from 2010 to 2018, this paper studies the interannual variation trend ofintensity and center of upwelling along the east coast of Guangdong Province, and discusses therelationship between upwelling intensity and wind speed, marine catches and upwelling intensity.The results show that in the past 15 years, the intensity of upwelling in the east coast ofGuangdong Province is generally strengthened; the center of upwelling is at 23.6°~23.7°N in allprobability, and there is a trend of northward movement.The coastal wind plays an important rolein the interannual variation of upwelling; excluding the damage of fishing structure and otherfactors, the correlation between marine catches and upwelling in Guangdong Province is very high,and the correlation coefficient reaches to -0.81.…”
