| 摘 要： | 为了找出唐山市主要灾害性天气的时空分布变化特征,以便为灾害性防御工作提供一定的理论参考,利用2004—2013年唐山地区主要灾害性天气出现日数资料,对该地区主要灾害性天气的时空分布变化特征进行分析。结果表明:雾、雷暴、大风、暴雨、霾等5类为唐山地区主要灾害性天气。大风和雾时间和空间分布都有很好的反相关关系,大雾出现日数相对减少且高发中心向南移动,秋、冬两季多发;大风出现日数近几年有增多的趋势且高发中心向北移动,春、夏季强对流大风较多,高发区集中在北部山区和南部沿海地区;雷暴和暴雨时间变化有很密切的正相关性,出现日数相对稳定,多集中在6—8月,雷暴北部山区多发,遵化市出现频次最高,暴雨各观测站每年约1—3日,且无明显地域性差异;霾日数增多,主要集中在唐山市中西部地区,逐渐成为影响唐山地区的又一类灾害性天气,并且爆发频次极高。

| Abstract: | In order to find the spatiotemporal distribution change characteristics of major disastrous weather in Tangshan City and provide a theoretical basis for disasters prevention, the variation of spatiotemporal distribution of major disastrous weather in this city was analyzed by using the data of disastrous days in Tangshan Region from 2004 to 2013. The results showed that there were 5 types of major disastrous weather in Tangshan Region: fogs, thunderstorms, strong winds, heavy rains and haze. The temporal and spatial distribution of strong winds and fogs had a good inverse correlation. The fog days showed a relatively declining trend, with the high-occurrence center moving toward south, frequently occurring in autumn and winter seasons. The strong wind days appeared a growing trend in recent years, with high-occurrence center moving toward north. Strong convective winds often occurred in spring and summer, with the high winds occurrence areas mainly concentrated in the northern mountains and southern coastal areas. The temporal variation of thunderstorms and heavy rains had a very close positive correlation, with relatively stable occurrence days, mostly occurring between June and August. Thunderstorms often occurred in the northern mountainous area, with maximum occurrence frequency in Zunhua. There were about 1-3 rainstorm days per year according to the report of observation stations, with no significant regional differences. Haze days were increasing, mainly occurred in the middle and west areas in Tangshan Region. Haze was gradually becoming another type of disastrous weather affecting Tangshan Region, with very high occurrence frequency. |
