Abstract

Based on the meteorological data in Qinhuangdao in latest 60 years and major mereorological disaster data in latest 10 years, the characteristics of climate change and occurrence of extreme severe weather in Qinhuangdao were analyzed using mathematical statistical method. To provide a climate basis for scientific planning of the development of industry, agriculture, tourism and cities, and to reduce risks and economic losses caused by meteorological disasters.The results show that the annual average temperature indicate a slow upward trend. The annual precipitation and the precipitation day show a decreasing trend, the interdecadal change of storm rainfall also shows a decreasing trend, while the change of heavy storm rainfall decreases first then increases. The annual variation of the average wind speed shows a decreasing trend, so as the annual gale day does. The studies of major meteorological disasters show that extreme weather events such as typhoon, heavy storm and extreme temperature occurred successively in Qinhuangdao in recent ten years, ranking a higher frequency than former time. As a result, the risk and impact of meteorological disasters have been aggravated. Since the extreme weather in recent ten years occurred more locally with higher intensity, the weather forecast is becoming more difficult and the meteorological risk is further enhanced.
