| 摘 要： | 为了更好地为雄安新区的规划和建设提供气候服务,本文以雄安新区3个国家气象站建站至2018年的逐日气象观测资料,系统分析了雄安新区的基本气候特征及其变化趋势;并采用2009—2018年精细化陆面同化数据和气候变化预估数据,分析了雄安新区最近10年以及未来10年降水量和气温的空间分布特征。结果表明：雄安新区平均年降水量480.8 mm,降水集中在6—9月;1961—2018年,雄安新区平均年降水量总体呈减少趋势,其中夏季减少趋势明显,而秋季增多趋势较为明显;预计未来10年,雄安新区大部分地区降水量增加。雄安新区年平均气温、平均最高气温和平均最低气温分别为12.6、18.7、7.3℃,年内（1981—2010年平均）,雄安新区7月份气温最高,1月份最低;1961—2018年,雄安新区平均气温、平均最高气温和平均最低气温总体均呈升高趋势,其中春季和冬季升温明显,其次为夏季,而秋季气温变化趋势不明显;预计未来10年,雄安新区气温将明显上升。雄安新区年平均日照时数2335.2 h,年内,春、夏季日照时数相对较多,秋、冬季日照时数相对较少;1968—2018年,雄安新区年日照时数总体呈减少趋势,其中秋季减少速率最快,春季相对最慢。雄安新区年平均风速1.7 m/s,年内,4月平均风速最大,1、8、12月相对最小;1961—2018年,雄安新区年平均风速总体呈减小趋势,其中冬季减小速率相对最大,夏季最小。

| Abstract: | To provide better climate services for the planning and construction of Xiongan New Area, this paper systematically analyzed the basic climate characteristics and change trend of the Area based on daily meteorological observation data of three national meteorological stations from their establishment to 2018. Spatial distribution characteristics of precipitation and temperature in recent 10 years and the next 10 years in Xiongan were analyzed and predicted by using the refined land surface assimilation data and climate change scenario data. The results showed that the average annual precipitation in Xiongan was 480.8 mm and the precipitation mainly occurred from June to September. During 1961-2018, the average annual precipitation in Xiongan showed a generally decreasing trend, with a significantly decreasing trend in summer and an obviously increasing trend in autumn. In the next 10 years, the precipitation in most areas of Xiongan will increase. The annual average temperature, maximum temperature and minimum temperature in Xiongan was 12.6, 18.7 and 7.3℃ respectively. In the year averaged from 1981 to 2010, the highest monthly temperature appeared in July and the lowest appeared in January. From 1961 to 2018, the average temperature, the average maximum temperature and the average minimum temperature in Xiongan all showed an upward trend, with obvious warming in spring and winter, followed by summer, while the trend in autumn was not obvious. In the next 10 years, the temperature in Xiongan will rise significantly. The annual average sunshine hours in Xiongan were 2335.2 hours. During the year, there were relatively more sunshine hours in spring and summer, and relatively less sunshine hours in autumn and winter. From 1968 to 2018, the annual sunshine hours in Xiongan showed a decreasing trend, with the fastest decreasing rate in autumn and the slowest in spring. The annual average wind speed in Xiongan was 1.7 m/s. During the year, the average wind speed in April was the largest, and the average wind speed in January, August and December was the smallest. From 1961 to 2018, the average wind speed in Xiongan was generally decreasing, with the largest decreasing rate in winter and the smallest in summer. |
