| 摘要: |
| 对广东省近50年的气温资料统计结果表明,广东省陆面气温增暖率为0.16℃/10年,低于全国和全球陆面增暖率;气候变暖的时空特征表现为冬季和春季明显大于夏季和秋季,沿海地区明显大于内陆地区,气候带向北移动的趋向明显,北热带区域面积在扩大,南亚热带区域面积在缩小,中亚热带区面积相对稳定。分析认为,在全球气候变暖的背景下,广东气候变暖具有地方性特征,主要是受大气环流、海温和人类活动等方面的综合影响。 |

| Abstract: |
| Based on temperature data in Guangdong in the past 50years, statistical methods are used to analyze the characteristics of temperature in spatial and temporal variation. The results show that land surface temperature warms by 0.16℃/10a in Guangdong. The range of warming was lower than the average of nationwide and global land surface. Furthermore, the temperature has a larger increase tendency in winter and spring and coastal areas than in summer and autumn and inland areas. Climate belts move towards the north obviously. North tropical zone is expanding, south subtropical zone is reducing and central subtropical zone is relatively stable. Under the global climate warming, characteristics of climate warming in Guangdong were influenced by atmosphere general circulation, sea surface temperature and human activities etc. |
