2014年初雪龙船为救援俄罗斯“绍卡利斯基院士”号船,在南极联邦湾被海冰围困,及时掌握雪龙船周边的冰情变化,以及给出准确的天气形势判断和预报,是此次雪龙船顺利脱困的关键。通过对雪龙船被困期间的海冰、气象和海洋环境状况综合分析发现,造成雪龙船被困的主要因素,一是由于雪龙船被困区域靠近大陆架,冰山较多,多年冰和当年冰夹杂在一起,海冰类型较为复杂;二是由于受连续多个气旋影响,在雪龙船受困海域,偏东大风持续时间长,风力大,导致海冰自东向西堆积,致使雪龙船被困。
At the beginning of 2014, as a rescue vessel for the Russian “Shakuliskii”, the snow dragon boat was besieged by the sea ice in the Antarctic Confederation Bay to keep abreast of changes in the ice conditions around the snow dragon boat, as well as to provide accurate weather forecasts and forecasts, Is the key to the successful removal of the snow dragon boat. Through the comprehensive analysis of sea ice, meteorology and marine environment during the trap of the snow dragon boat, it is found that the main factors causing the snow dragon trapped are that the trapped area of the snow dragon boat is close to the continental shelf, there are more icebergs, many years of ice and current ice inclusions Together, the type of sea ice is rather complicated. Second, due to the continuous influence of multiple cyclones, the northerly gale lasts long and the wind force is large in the area where the snow dragon boat is trapped. As a result, sea ice buildup from east to west, causing the snow dragon boat to be trapped .
