【摘要】 利用涠洲岛气象站自建站至2010年的气象观测资料,分析总结近五十年来广西海岛的气候特征、气候变化规律与气象灾害特征。分析结果表明,随着全球变暖广西海岛的气候发生了明显变化,气温显著升高,特别是90年代后期以来,升温更加显著,冬季对气候变暖的贡献最大;年降水量呈增多趋势,主要来自夏季降水量增多的贡献,从80年代开始降水量增加趋势明显;广西海岛主要的气象灾害发生的频率和强度出现明显变化,台风影响个数略有减少,大风日数呈减少趋势,暴雨、旱涝灾害有所增加,极端天气气候事件造成的灾害损失呈增大趋势。更多还原

【Abstract】 Based on the meteorological observation data of Weizhoudao station in island of Guangxi during recent 50 years, the climate characteristics and the regularity of meteorological disasters and climate change are analyzed. Results show that the climate of island has been obviously changed due to global warming. The temperature significantly increases, especially since late 1990’s, the increasing trend is more obvious with more contributions made by Winter. The increase of annual precipitation dues to the sunmmer’s contribution, and the tendency is significant from1980’s.The frequency and strength of the main meteorological disasters of Guangxi’s island is changing obviously: the number of typhoon decreasing slightly, high wind day tending to decrease, storm rain, drought and flood disasters increasing and disaster losses of extreme weather and climate events tending to increase.更多还原
