Description
Summary:Under the background of global warming, the interannual variation trend of coastalupwelling has become a research hotspot of global climate change in recent years. 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.
