| Abstract: | Based on the Germany Koldwey Station's 1994-2003 conventional ob- servation hourly data,this paper conducts a statistical analysis on the short-term climate characteristics for an arctic tundra region(Ny-lesund 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-lesund rose above 0℃ even during deep winter sea- son 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-lesund 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-lesund 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-lesund area shows a good a- greement for winter season and a significant difference for summer season. |
