摘要
分析了海南岛有代表性的5个市县气象站从建站到2000年的地面气象观测资料。结果表明:50 a来,年平均气温约上升了0.7 ℃,冬季气温的增加是引起年平均气温上升的主要因素;降水量的年际变化不显著,但干旱出现的几率加大;各地年平均风速都有不同程度的降低,登陆台风数也有减小的趋势,但影响时间延长。
The climatic changes of Hainan Island in the past 50 years were analysed based on the observational ground data from 5 weather stations in Hainan. Results showed that the annual mean temperature had hoisted about 0.7℃ since 1950 owing to temperature increase in winter (January). The annual rainfall changed less while the probability of drought increased. The annual mean wind speed and the number of landing tropical cyclones are cut down but the time for cyclone influence prolonged in recent 50 years.
