THE STUDY OF CLIMATE CHANGE TREND IN VIETNAM: A CASE STUDY IN DANANG CITY

Abstract

This paper aims to present the climate change trend in Vietnam, a typical case study in Danang City. With the use of statistical analysis, which is non-parametric Mann-Kendall test, the research conducted the test of climate change trend based on the study of recent precipitation and temperature trends. The results were evaluated based on the statistical analysis at the 0.05 level by ProUCL 4.1 software. The research showed clear signs of climate change related to precipitation and temperature factors. In general, precipitation change in Danang had the upward trend in the observed time series (p <0.05). However, there existed increasing trend of the precipitation in January, March, August and a decreasing trend in June during the observed period. According to the scenario in 2100, the average precipitation in Danang will increase by about 1.04% in comparison with the period 1980 – 1999. Regarding temperature factor, based on the results of the Mann-Kendall test, June’s average temperature in Danang will increase about 0.3150C in every ten years. Therefore, urgent solutions are required to reduce the increase and adapt to climate change.
