January 6, according to the State Oceanic Administration Web site news, national marine forecasting station that the "Snow Dragon" ships to evacuate the best time window (East eight local time zone) at noon on January 7 and 8th, westerly winds that occur during favourable sea-ice ice conditions eased, "Snow Dragon" boat out favorable. Current material on board is sufficient, expedition in good condition, the "Snow Dragon" boat is waiting for the best time to break through, part scientific expedition projects go ahead.
On January 2, the 30th Antarctic expedition and the "Snow Dragon" polar research vessel completed in Russia, "Shao Kaliski academicians" trapped 52 passengers, rescue work, by the surrounding complex of sea ice and hydro-meteorological conditions, which affect, withdrawal of sea ice when under siege. Integrated sea ice live, and future weather situation and the currents forecast analysis, national marine forecast Taiwan think, "Snow Dragon" ship evacuation of best time window for (local time East eight district) January 7 early this morning to 8th noon, this during appeared of partial westerly conducive to sea ice ice love mitigation, on "Snow Dragon" ship out enabling; 9th zhihou, wind will becomes Southeast to, will accelerated sea ice stacked, not conducive to out.
According to the national marine forecasting Center of the polar environment studies forecast Office Director Zhang Lin introduced on 6th, the "Snow Dragon" vessel trapped waters wind from the East to the Northwest, the wind gradually strengthened. 7th morning, winds will be westerly winds will reach 5-level ~6-level, instantaneous wind will reach seven or eight levels. "This kind of meteorological conditions more conducive to ' snow Dragons ' ship relief. Warm, moist air will loosen the sea ice, ' snow Dragons ' vessel can select a loose pack ice to break through. "Zhang Lin said.
Expedition Party Secretary, temporary team leader Liu shunlin said: "the loving care of the Party Central Committee and the State Council were encouraged by all expedition. At present, the ' Snow Dragon ' boat supplies sufficient players emotionally stable, personnel and equipment are safe, assured people of the motherland. ”
On January 5, actively sought out at the same time, the "Snow Dragon" part scientific expedition on board the project as usual.
At present, the "Snow Dragon" position in longitude 144 ° 29 ', latitude 66 ° 41 '. Under the influence of continuing strong southeast winds, sea ice in the waters where the ship constantly clustered stacking, intensity of 10 per cent, 40% per cent of ridged sea ice, some ice up to 3 m ~4 m. According to 5th early this morning gets of satellite remote sensing information for analysis, currently "Snow Dragon" ship around has two obviously of larger iceberg, a iceberg size for 900 m x500 m, by "Snow Dragon" ship Northeast 2.9 km Department drift to North to 5 km Department; another a block iceberg size for 200 m x600 m, is located in "Snow Dragon" ship Southeast 8 km Department, currently this two block iceberg on "Snow Dragon" ship is not constitute threat. Large ice floes on the East side and "Snow Dragon" vessel remains relatively stable, a slow drift away from the "Snow Dragon" vessel nearest large ice floe size 600 m × m, distance of about 700 m. At present, the "Snow Dragon" vessel water area on the East side nearest distance of about 14.8 km, compared with shrink 3.2 km a day earlier.
Expedition active organization ship Shang meteorological, and sea ice observation, and physical marine, and ship navigation, related professionals strengthened sea ice, and iceberg changes, work, collected and analysis near meteorological, and currents, and sea ice, information, and combines domestic polar visits support units and abroad parties made to of related information for study, in ensure security of premise Xia, stay enabling meteorological, and hydrological conditions appeared Shi again snagged breakthrough.
"Snow Dragon" 9 m ship Gage, pass before discharge, along with fuel, fresh water draining, the actual draft less than 9 metres. On January 3, the "Snow Dragon" ship began pumping sea water into the ballast tank, to keep the ship balanced and add draft to facilitate the next ice-breaking.

中新网1月6日电 据国家海洋局网站消息，国家海洋预报台认为，“雪龙”船撤离的最佳时间窗口为(当地时间东八区)1月7日凌晨至8日中午，这期间出现的偏西风有利于海冰冰情缓解，对“雪龙”船脱困有利。目前船上物资充足，考察队员状态良好，“雪龙”船正等待最佳突围时间，部分科学考察项目照常进行。
1月2日，中国第30次南极考察队暨“雪龙”号极地考察船在完成对俄罗斯“绍卡利斯基院士”号被困52名乘客救援工作后，受周围复杂海冰和水文气象条件等影响，在回撤时受到海冰围困。综合海冰实况、未来天气形势及海流预测分析，国家海洋预报台认为，“雪龙”船撤离的最佳时间窗口为(当地时间东八区)1月7日凌晨至8日中午，这期间出现的偏西风有利于海冰冰情缓解，对“雪龙”船脱困有利；9日之后，风向将变为东南向，会加速海冰堆积，不利于脱困。
据国家海洋预报中心极地环境研究预报室主任张林介绍，6日，“雪龙”船被困海域风向将从东风转为偏西北风，风力逐渐加强。7日凌晨，风向将变为西风，风力将达到5级~6级，瞬时风力将达到七八级。“这样的气象条件比较有利于‘雪龙’船解困。暖湿气流将会令海冰有所松动，‘雪龙’船可选择松动的浮冰进行突围。”张林说。
考察队临时党委书记、领队刘顺林介绍说：“党中央、国务院的亲切关怀让全体考察队员深受鼓舞。目前，‘雪龙’船补给物资充足，队员情绪稳定，人员和设备都很安全，请祖国亲人们放心。”
1月5日，在积极设法摆脱困境的同时，“雪龙”船上部分科学考察项目照常进行。
目前，“雪龙”船位于东经144°29′、南纬66°41′。受持续强劲东南风影响，船舶所在海域海冰不断聚集堆积，密集度达十成，海冰脊化比例达四成，部分冰厚达3米~4米。根据5日凌晨获取的卫星遥感资料进行分析，目前“雪龙”船周围有两个明显的较大冰山，一个冰山大小为900米×500米，由“雪龙”船东北2.9公里处漂移至北向5公里处；另一座冰山大小为200米×600米，位于“雪龙”船东南8公里处，目前这两座冰山对“雪龙”船尚不构成威胁。东侧大浮冰与“雪龙”船距离保持相对稳定，漂移速度较慢，离“雪龙”船最近的大浮冰大小为600米×600米，距离约700米。当前，“雪龙”船距东侧清水区域最近距离约为14.8公里，较前一日缩减了3.2公里。
考察队积极组织船上气象、海冰观测、物理海洋、船舶航海等相关专业人员加强海冰、冰山变化等工作，搜集并分析附近气象、洋流、海冰等资料，并结合国内极地考察支撑单位和国外各方发来的相关信息进行研判，在确保安全的前提下，待有利气象、水文条件出现时再择机突破。
“雪龙”船满载吃水深度为9米，之前经过卸货，加之油料、淡水不断消耗，实际吃水深度已不足9米。1月3日下午，“雪龙”船开始向压水舱注入海水，以保持船体平衡和增加吃水深度，以利下一步破冰。
