Pack ice area over the puddle near Snow Dragon, to usher in ice breaker Snow Dragon Windows | | ice floe | puddle _ news

Beijing authorities wide nets, January 6 (reporter Guo m) according to voice of evening peak reported the news, SOA message called the afternoon of 6th to 8th, at noon, Snow Dragon, the area could change once the weather and sea ice processes, it might give "Snow Dragon" break through to find a breakthrough. Snow Dragon, the latest progress reporter Guo m update.

Xuelong ship around noon the weather was cloudy and snowing, but Southeast wind, wind down, is in the starting phase of the transformation of the system, subsequent winds shift East, Northeast, North, and then turned to the Northwest and West.

The xuelong ice area on the East side, test results yesterday and has expanded, mainly because of the emergence of Epitaxial ice ice floe loosely appeared, and high-resolution satellite imagery shows that in the pack ice zone has existed for more than 100 more puddle, water is ice-free areas. Puddle appears suggests that first-ice intensity has waned, the second note appeared to melt the ice, so it could also weaken the strength of the third, once we xuelong entered the region, the resistance will be greatly reduced. This is beneficial to the xuelong ship into and out of this area. Xuelong ice area around there have been big changes, xuelong will now require intensive strengthening of sea ice, currents, weather and wind direction conversion monitoring, take everything out of time, get out.

Close to the snow Dragon, a length of about 1 km at the tip, This block iceberg is is located in Snow Dragon, Southeast direction 7.5 km, mobile to North direction 4.5 km, during from Snow Dragon, recently distance about for 2.5 km, according to SOA polar Office Director Qu Tanzhou analysis: If iceberg keep place not moving of State, we Snow Dragon and it keep must distance, should is no dangerous and threat of, so-called of dangerous and threat is we in to outside breakout of process in the, iceberg received was ice block of power also in weakened, if iceberg along currents of direction fast drift words, will see we ship and iceberg of relative distance has. Icebergs move mainly under the influence of ocean currents and the speed faster than ours, so the break through in the course of and be sure to note changes near the tip of the iceberg. Avoid a new threat to break through. In addition, said Qu Tanzhou, an overall analysis of the current sea ice around the snow Dragon, and the weather is changing, predicting the weather system to convert, but with the weather system transformation will be brought to Snow Dragon, freed of good timing, but that does not mean the snow Dragon, instantly a while ago.

Qu Tanzhou: we is expected to from 6th, of afternoon to 8th, of noon before and after, will appeared a weather system of conversion period, specific, is wind of conversion, this on Snow Dragon, ship around ice of roves and blowing moved words is enabling of, but not meant with a began we of out on can success, often best period in conversion period behind appeared, impossible wind a go, ice immediately on bulk off, it also needs a continued of force of role. Together with the xuelong according to degree of loose flow, wind speed and ice to capture timing out, you are actually taking advantage of the strength of the process cannot, therefore, understand the transformation of weather, we'll have the best out of it. At present, preparation for xuelong is taking some out, for example, prepared by helicopter, in case of visibility and weather permitting, to break through sea ice in the direction of being more extensive survey and inspections. In the vicinity of ice, creating a xuelong ship maneuvering space, once the changes take action, do not convert weather system into line and our actions, can be a lagging process, where it is easy to misunderstand.

雪龙号附近浮冰区出现百余水坑 迎来破冰窗口 |雪龙|浮冰|水坑_新闻资讯

　　央广网北京1月6日消息 (记者郭淼)据中国之声《新闻晚高峰》报道，国家海洋局消息称6号下午到8号的中午，雪龙号所处的地区可能会有一次天气和海冰的变化过程，这可能会给"雪龙号"的突围找到一个突破口。而雪龙号最新进展，记者郭淼介绍最新情况。

　　雪龙船周边中午的天气是阴而且有降雪的，但是原来东南向的风，风力在减弱，是处于系统转换的开始阶段，后续的风向逐渐转为偏东，偏东北、偏北向，然后再转向偏西北和偏西。

　　在雪龙船东侧的浮冰区，和昨天检测的结果有所扩大，这主要是因为出现了外延冰区的浮冰出现了松散的情况，而且高分辨率的卫星云图显示，在这些浮冰区里出现了100多个水坑，就是无冰区的水区。水坑的出现表明，第一冰的密集度有所减弱，第二说明冰出现了融化现象，所以它的强度也在减弱，第三，一旦我们雪龙船进入这个区域，阻力会大大的减少。这样对雪龙船进入这个区域和脱困是有利的。但是雪龙船周边大的乱冰区域还没有发生大的变化，所以雪龙船现在需要密集加强对海冰、海流、天气和风向转换的监测工作，抓住一切可以脱困的时机，抓紧脱困行动。

　　在雪龙号附近的一座长约1公里的冰山，这座冰山是位于雪龙号东南方向7.5公里，移动至正北方向4.5公里，期间距雪龙号最近距离约为2.5公里，据国家海洋局极地办主任曲探宙分析：如果冰山保持原地不动的状态，我们雪龙和它保持一定距离，应该是没有危险和威胁的，所谓的危险和威胁是我们在向外突围的过程中，冰山收受到浮冰阻挡的力量也在减弱，如果冰山顺着海流的方向快速漂移的话，就要看我们船和冰山的相对距离了。冰山的移动主要是受海流的影响，而且漂移的速度比我们船要快，所以在突围的过程中，还一定要注意附近冰山的变化。避免在突围中构成新的威胁。另外，曲探宙说，总体分析目前雪龙号周边的海冰和天气正在发生变化，预示着天气系统进入转换时期，而随着天气系统的转化将给雪龙号脱困带来好的时机，但并不意味着雪龙号立刻就能脱困。

　　曲探宙：我们预计从6号的下午到8号的中午前后，会出现一个天气系统的转换期，具体来讲就是风向的转换，这对雪龙号船周边浮冰的飘散和吹移的话是有利的，但是不意味着一开始我们的脱困就能成功，往往最佳期在转换期后面出现，不可能风一转，冰马上就散掉，它还需要一个持续的力的作用。在加上雪龙船要根据流向、风向和冰的疏松程度来捕捉时机进行脱困，实际是借力的过程，因此不能理解天气一转化，我们就具备了最佳脱困时期。目前，雪龙船正在采取一些脱困的准备工作，比如说准备用直升机，在能见度和天气允许的情况下，对突围方向的海冰进行更大范围的勘察和检查。另外在附近的冰区，创造一个雪龙船机动的空间，一旦发生变化后能迅速的采取行动，不要把天气系统的转换和我们的行动一致起来，可能是一个滞后的过程，这也是容易误解的地方。
