Abstract By using the linear trend method,the comprehensive diagnosis system of hydrological variation and the standardized precipitation index,this paper analyzes the precipitation and temperature series in Maoming City from 1980 to 2021.It was found that the precipitation in Maoming City showed a slight decreasing trend,with an annual decrease of 1.04 mm,while the temperature showed a more obvious upward trend,with an increase of 0.156 ℃ per 10 years.The precipitation and temperature jumped in 1986 and 2019 respectively.The standardized precipitation index revealed that the climate change in Maoming City began to be dry in 2020.
