This paper uses the daily meteorological data at 19 representative locations over the recent 50 years to analyze Northern Vietnam’s climatic change and its effects on rice production.EOF(Empirical Orthogonal Function),integral regression and other statistical methods are adopted to analyze the correlation between rice yields and many meteorological elements such as temperature and precipitation etc,the impact of meteorological disasters on rice yields since 1959,and the effect of different meteorological factors in different growth phases on rice yields.At last,several measures for rice production are suggested on the background of future climatic warming.
