通过现场观测和长期时间序列研究了弗拉姆海峡地区海冰漂流与气旋活动的关系。在1999年的一次实地活动中，使用一架研究飞机和漂流冰浮标确定了大气强迫和冰漂流。一个气旋进入实验区，造成冰漂移速度的时间增加。长期研究的基础是16年的气旋统计数据和模型、卫星和声纳冰漂估计。气旋的实际影响取决于其通过弗拉姆海峡的具体路径。平均而言，气旋增加了北极冰通过弗拉姆海峡的输出。
The relation between sea ice drift and cyclone activity in the Fram Strait region was studied by both in situ observations and long-term time series. In a 1999 field campaign, the atmospheric forcing and the ice drift were determined using a research aircraft and drifting ice buoys. One cyclone entered the experimental area and caused a temporal increase in ice drift speed. Long-term studies are based on 16 years of cyclone statistics and model, satellite and sonar ice drift estimates. The actual impact of a cyclone depends on its particular track through Fram Strait. On the average, cyclones increase the Arctic ice export through Fram Strait.
