Based on the meteorological and historical data in Yulin area of Shaanxi Province from 1961 to pres-ent, statistical analysis was conducted. The objectives of this study were： (1) Examine the relationship among precipitation, temperature, natural disaster events, and the ENSO(E1 Nino/Southern Oscillation) events. (2) Reveal the correlation between ENSO events and the climate of Yulin area. (3) Identify the peri-odicity of the precipitation and temperature changes. The results show that since 1954, the climate was war-ming significantly in Yulin area, with an annual temperature increasing rate of 0. 025℃ per year. However, the annual total precipitation decreased at rate of 1. 740 mm per year. In E1 Nino years, the temperature was O. 12℃ higher than that in normal years, and in La Nina years, the annual average temperature remained same to that in normal years. E1 Nino event lowered annual total precipitation approximately 8 mm than the normal years, while La Nina events did approximately 3 ram. The temperature and precipitation of the area changed at a short period of 3 years and a long period of 20 years. ENSO events was prone to cause high tem-perature and drought disasters, and ENSO warming events caused more meteorological disasters than ENSO cold events in the study area according to statistical analysis.
