[1]火星探测车（MER）在伊希地平原（Isidis Planitia）着陆点的11，497个风（风相关）特征的方向反映了来自西北的形成风，与火星区域尺度大气模型预测的强烈晨风一致。在Terra Meridiani潜在MER站点绘制的3296个风成特征的方向表明了多方向的风模式。Terra Meridiani站点的结果与作为火星季节函数（由大气环流模型预测）改变方向的微风和每日发生的不稳定风（由区域尺度大气模型预测）一致。这两个地点的结果表明，考虑到一天中的时间和当地地形，大气模型的预测基本正确。
[1] Orientations of 11,497 aeolian (wind related) features at the potential Mars Exploration Rover (MER) landing site in Isidis Planitia reflect formative winds from the northwest and are consistent with strong morning winds predicted by a regional-scale atmospheric model for Mars. Orientations of 3296 aeolian features mapped at the Terra Meridiani potential MER site suggest multidirectional wind patterns. The results for the Terra Meridiani site are consistent with gentle winds which change direction as a function of Martian season (predicted by a general circulation model) and erratic winds that occur diurnally (predicted by a regional-scale atmospheric model). Results for both sites give confidence that the predictions from the atmospheric models are basically correct when time of day and local topography are taken into account.
