Abstract

The article presents the changing trend of climate factors in the Southern region. The study uses a series of monitoring data from 1980 to 2022 in order to assess the trends of the annual average temperature, rainfall, humidity, and evaporation factors in the Southern region. The assessment of the change of climate factors using linear regression was conducted at a number of main meteorological stations in the Southern region, with reliable data series and sufficient length to serve the needs of statistical calculation. The results indicated that the annual average temperature tended to increase at most stations with an average increase of about 0.013 - 0.04 3 ^oC/year, rainfall and evaporation tended to increase and decrease at some specific stations in the area while the humidity tended to decrease at the insignificant level in the range of 0.01 - 0.11 mm/year. The study aims to provide information on climate trends for production planning, socio-economic development, and disaster prevention in Ho Chi Minh City.
