摘要
应用一维K闭合OSUPBL模式和ARCSCM极地柱模式,采用SHEBA观测资料和ECM- WF的输出结果作为模式的初始场和外强迫场,对SHEBA试验所在地(75°N,150°W)单点的北极大气边界层特征,进行了初步的模拟并与SHEBA资料进行对比分析。研究表明,这两个模式都具有较好地模拟单点北极大气边界层特征的能力。OSUPBL模式在垂直高度上的高分辨率,使其能够更好地反映大气边界层内部的细微变化特征。ARCSCM模式中考虑了比较多的物理过程,且需要提供比较完整的初始场、边界条件和侧向强迫,并每小时更新,模拟结果更符合实际情况。对模式的不足和下一步的研究也进行了讨论。
The characteristics of polar atmosphere boundary layer have remarkable response to the flux variation at ocean-air interface in polar region. Both Ocean-Atmosphere-Ice Interactions （OAII） research and the Surface Heat Budget of the Arctic Ocean （SHEBA） project show that the study of structure and physical characteristics of polar atmosphere boundary layer is very important for learning ocean-air interface flux and polar environmental change. The research on the polar ocean-air interface flux and the polar atmosphere boundary layer is briefly introduced in this paper and the preliminary numerical simulations are carried out by using a simple onedimensional K-closure model and an Arctic single-column model, respectively. The output data from the European Centre for Medium-Range Weather Forecast （ECMWF） model are used as the lateral forcing in the simulation and the results from the simulation are analyzed and compared with the SHEBA data in the paper.
