利用我国北极黄河站所在地,德国Koldewey站1993-2003年的资料,对新奥尔松地区的地表辐射特征进行了初步分析。结果表明,由于云的影响,新奥尔松极昼期间的日照百分率仅为32.2%。暖季由于下垫面地表冰雪融化,地表反射率迅速减小,地面吸收辐射和地面有效辐射都迅速增大。全年累计的净辐射为正值;暖季是接受太阳辐射能的主要时段,寒季接受的太阳辐射能极少。虽近10年来新奥尔松地区的气温增加十分显著,但各辐射量的变化趋势不明显。地表辐射实测值与同期NCEP/NCAR相邻格点逐日资料的比较表明,NCEP资料对各辐射项模拟的精度不高。 相似文献

利用我国北极黄河站所在地,德国Koldwey站1994—2003年的逐时常规气象资料,对北极苔原Ny lesund地区短期气候特征进行了初步分析。结果表明,由于受北大西洋暖流的影响,该地是北极同纬度温度最高的地区。岛上气候温暖湿润,即使在隆冬季节,日平均气温都可以升至0℃以上。全年平均风力较小,以东南(SE)风居多。该地区平均增温速度为0. 68℃/10a,是北极增温较快的地区之一。与同期我国北冰洋浮冰区考察数据相比较,Ny lesund气候更温暖湿润,风速要小得多。在Ny lesund地区,美国国家环境预测中心/美国国家大气研究中心(NCEP/NCAR)的近地面气温的再分析结果,与Koldwey站实测常规地面资料相比,在冬季基本一致,而在夏季则差异较大。 相似文献

Based on the Germany Koldwey Station's 1994-2003 conventional ob-servation hourly data,this paper conducts a statistical analysis on the short-termclimate characteristics for an arctic tundra region(Ny-lesund island)where ourfirst arctic expedition station(Huanghe Station)was located.Affected by theNorth Atlantic warming current,this area has a humid temperate climate,andthe air temperature at Ny-lesund rose above 0℃ even during deep winter sea-son during our research period.The wind speed in this area was low and appearedmost at southeast direction.We find that the temperature at Ny-lesund rose inthe faster rate(0.68℃/10 a)than those at the whole Arctic area.Comparedwith the floating ices where our expedition conducted in the Arctic,Ny-lesundwas warmer and more humid and had lower wind speed.Comparison of the nearsurface air temperature derived by NCEP/NCAR reanalysis to the conventionalmeasurements conducted at the Koldwey site in Ny-lesund area shows a good a-greement for winter season and a significant difference for summer season. 相似文献

在中国气象局政策法规司行业管理与标准化处的组织领导下，2006年我院的行业标准建设取得了显著进步。我院共承担了2006年度的6项气象标准项目和2007年度5项气象标准项目、11项国家标准体系的编制工作（有1项为直接下达）。为及时了解掌握各科研人员承担的气象标准项目进展隋况，保证中国气象局2006年以前下达的各项气象标准制定任务按时保质完成，我院也十分注重标准项目的日常管理，对已完成的气象标准项目及时组织审查验收，并督促其尽陕完成审查和报批手续。 相似文献

Based on the Germany Koldwey Station＇s 1994-2003 conventional observation hourly data, this paper conducts a statistical analysis on the short-term climate characteristics for an arctic tundra region （Ny-Alesund island） where our first arctic expedition station （Huanghe Station） was located. Affected by the North Atlantic warming current, this area has a humid temperate climate, and the air temperature at Ny-Alesund rose above 0 ℃ even during deep winter season during our research period. The wind speed in this area was low and appeared most at southeast direction. We find that the temperature at Ny-Alesund rose in the faster rate （0.68℃/10 a） than those at the whole Arctic area. Compared with the floating ices where our expedition conducted in the Arctic, Ny-Alesund was warmer and more humid and had lower wind speed. Comparison Of the near surface air temperature derived by NCEP/NCAR reanalysis to the conventional measurements conducted at the Koldwey site in Ny-Alesund area shows a good agreement for winter season and a slgnificant difference for summer season. 相似文献
