| 摘 要： | 根据南四湖畔4个陆面台站近20年的大风记录,对南四湖大风天气的基本气候特征进行了统计分析,结果表明:南四湖地区大风以西北风为主,春季出现大风日数最多,秋季最少。自90年代末大风日数呈逐渐减少趋势,南四湖大风频次逐年减少,造成该结果的原因除了大气环流背景方面的影响因素外,还可能与全球气候变暖、测站周围局地环境改变、人工防护林带面积扩大有关。

Analysis of Gale Climatic Characteristics in the Southern Four Lakes during the Past 20 Years |
| |
| Abstract: | According to the records of gale at 4 land stations around the southern four lakes during the past 20 years,the basic climate characteristics of gale weather in the southern four lakes were analyzed.The results showed that the gale in the areas of the southern four lakes was mainly as northwest wind and it occurred mostly in spring and least in autumn.Since the end of 1990s,the gale days began to show a gradually decreasing trend.The gale frequency of the southern four lakes gradually decreased.The causations of these results not only included the influencing factors of atmospheric circulation background,but they were also relevant with the global warming,local environmental changes around stations and the area enlargement of artificial shelterbelt. |
