南极半岛和南极西部是气候变化的重点地区。在未来几十年到几个世纪内,该地区的融化可能导致海平面上升几米,该地区的气候轨迹显然具有全球意义。如果表面或海洋基底融化成为表面物质平衡的重要组成部分,它可能有助于削弱边缘冰架,从而显著加速目前搁浅的冰流排入南大洋。因此,更好地了解南极洲西部的气候变暖具有强有力的科学和社会理由。该项目将结合联合收割机现有的温度记录,从载人和自动气象站,卫星数据,ERA中期再分析,以及近200年冰芯提供的前景(钻孔)数据重建到WRF模式中,以产生整个西南极冰盖(WAIS)的高分辨率(10km)表面温度历史。这将有助于解决最近关于WAIS地区变暖程度的分歧。 还将研究在有和没有卫星记录对重建的影响的情况下气候重建的其他比较。
英文摘要
The Antarctic Peninsula and West Antarctica are focus areas for climate change. With up to several meters of sea level rise potentially resulting from melting of this region in the coming decades to centuries, the climate trajectory of this region is clearly of global relevance. If surface, or ocean basal melting becomes a significant component of the surface mass balance, it could contribute to the weakening of fringing ice shelves with a resulting marked acceleration of currently grounded ice stream discharging into the Southern Ocean. Thus, better understanding of the climate warming in West Antarctica has strong scientific and societal justification.The project will combine existing temperature records from manned and automatic weather stations, satellite data, ERA interim reanalysis, and the perspective provided by recent (~200) yr ice core (borehole) data reconstructed into the WRF model to yield high resolution (10km) surface temperature history throughout the West Antarctic Ice sheet (WAIS). This will help resolve recent disagreement on the extent of warming in the WAIS region. Additional comparisons of the climate reconstructions with and without the influences of satellite records on the reconstructions will also be investigated.
