中文摘要:
      利用东南极高原熊猫-1自动气象站2011年2月—2012年1月观测的辐射资料和相关资料,对辐射分量和辐射平衡的季节变化进行了研究。结果表明,夏季是东南极高原获得太阳能的主要时段,总辐射通量夏季平均为365.0 W/m2,总量达到2752.1 MJ/m2,占全年总辐射量的58%。各个季节均能出现总辐射瞬时值大于大气顶水平总辐射,春季发生频率最高,冬季最小,总辐射平均日变化呈单峰型。大气长波辐射除夏季外,日变化不明显。冰雪面长波辐射除冬季外,各季节平均日变化呈明显的单峰单谷型。净辐射12月和1月为很小的正值,其他月份为负值。年平均净辐射为 -8.7 W/m2,表明地表相对于大气为冷源。该站的辐射平衡特征与其他南极内陆高原站相似,雪面具有强烈的辐射冷却效应,导致净辐射绝对值都小于下降风区。
英文摘要:
      Based on the radiation data of Panda-1 AWS in eastern Antarctic Plateau from February 2011 to January 2012, the radiation balance characteristics of this region were analyzed. The results show that: Summer is the main periods absorbing solar energy when the daily mean downward solar radiation is 365.0 W/m2, and about 2752 MJ/m2 soalr radiation reaches the surface, accounting for 58% of the total solar radiation( 4776 MJ/m2). The situation of the instantaneous downward shortwave radiation higher than the atmosphere top radiation is found in every season, and the frequency is highest in spring and lowest in winter. The mean diurnal variations of the downward shortwave radiation and the upward shortwave radiation show a single peak curve. Except summer, the downward long wave radiation almost has no diurnal variation. The upward longwave radiation appears to be in the form of single kurtosis and single valley in each season except summer. For the whole year the net radiation is basically negative, and only in December and January it is small positive value, with the annual mean net radiation of -8.7 W/m2. The land compared to the atmosphere is a cold source. Panda-1 has similar radiation balance characteristics to other Antarctic inland plateau sites, where the lackness of strong winds forces, and the small surface longwave radiation heat loss, lead the winter and annual mean net radiation to being less than the katabatic wind zone.
