  snow drift
    According to above mentioned rules,regionalization of snow drift of China can be divided into 2 regions, 3 sub_regions,13 belts,39areas and 131 sub_areas. Meanwhile the all year and seasonal areas with serious,middle and light degree sub_areas are divided from low regionalization unit system,therefore enhance its practical value.

  snow drift
(3) Upper zone (snow drift avalanche zone): the movement of snow mantle creates disaster in this zone.
      
Calculations are made of the effects of thermal stability under a range of conditions, over the sea and land, on the physical factors (including the critical wind speed) affecting dust-storm generation, snow drift, and rough sea conditions.
      
The snow drift rate caused by creep, that is, by the ripple migration, was estimated to amount, at least, to 6% of the total snow drift rate.
      
Wind component fluctuations have been decomposed into contributions of large and small-scale eddies to study turbulence structures in the atmospheric surface layer over snow-covered pack ice for a case with snow drift and another without.

This paper aims to analyze the geographical environment in the area of Tianshan Stahon for Snow & Avalanche Research, based on about 30 years'data of climatic observation at the station and some recently investigated results on geomorphology, soil, vegetation,hydrology and natural hazards. By systematically analyzing and studying the information mentioned above, the results show that there are the obvious physiographical features in the area. Generally, following five aspects can be used to demonstrate these characteristics:(1) There is an obvious vertical zonality on geomorphology, vegetation and soil in the area. From piedmont to summit, 5 zones can be differentited: a. alluvial valley plains below 1500m a.s.l: wild fruit woods mainly mcluding wild apple trees, wild walnut trees and mountainous apricot distribute in the zone, they play an important role in vegetation structure and in phytogeographical and paleo-ecological research of Tianshan Mountains; b.mid-mountain zone between 1500 and 2800 m a.s.l.: Grasslands distribute on sunshine-slopes and forests on sheltered-slopes; c. subalpine zone between 2800 and 3200 m a.s.l.: Alpine meadow distributes in the zone, d. alpine periglacial & melting-freealng zone between 2800 and 3500m a.s.l.: Periglacial landform can be found here; e. extreme alpine zone above 3500 m a.s.l.: Modern glaciers distribute in the zone. (2) Tn the area, it is cool and humid in summer, and is cold and dry in winter. Snow cover is thick (80 cm in average and 150 cm in maximum) and its duration is long(151 days in average). According to the data of the station, the mean monthly air temperature is only 13.8℃ in July and -14.3℃ in January. The recorded maximum precipitation is 1140.8 mm. Precipitation in summer shares 70% of annual amount. (3) Natural hazards, such as avalanches and drifttug snow, occur seriously and frequently in the area. (4) Spring noods with a lasting period of one month occur in the rivers here. The discharge is controlled by air temperature and snow storage in snow-melting season. (5) Tbere is a great tourist attraction in the area. Tt has become an important tourist area in western Xinjiang.

中国天山积雪雪崩站站区自然地理垂直地带完整.降水丰富,最大达1140.8mm.各半年降雪量占年降水量的30%左右.积雪深度多年平均80cm.深厚的积雪使站区每年冬季都发生雪崩和风吹雪灾害,成为天山大陆性雪崩研究的天然场所.同时,站区生态与环境良好,植被、土壤种类集天山之大成.站区旅游资源引人入胜.北有“东方阿尔卑斯”之称的乔尔马;南有巴音布鲁克天鹅湖,均由天山公路与本站相连通.

In the northeast,northwest and southwest of China,snow drift often occurs in winter and spring,causing damage to communications and transportation,factories and mines as well as to agriculture and livestock breeding.Regionalization of snow drift is the research results when snow drift science to more higher level,and also a foundation research work for national economy construction. Snow drift and its future variational tendency is analysed.The theory,principle,requirement and division unit system,and index...

In the northeast,northwest and southwest of China,snow drift often occurs in winter and spring,causing damage to communications and transportation,factories and mines as well as to agriculture and livestock breeding.Regionalization of snow drift is the research results when snow drift science to more higher level,and also a foundation research work for national economy construction. Snow drift and its future variational tendency is analysed.The theory,principle,requirement and division unit system,and index method on regionalization are proposed.This division is an improvement upon the former, putting the snow drift and avalanche into two different kinds, defining a united index and three grades and dividing five grades by multi_index. According to above mentioned rules,regionalization of snow drift of China can be divided into 2 regions, 3 sub_regions,13 belts,39areas and 131 sub_areas.Meanwhile the all year and seasonal areas with serious,middle and light degree sub_areas are divided from low regionalization unit system,therefore enhance its practical value.

分析了我国风吹雪及其变化趋势,指出风吹雪和雪崩不能放在一起区划的原因。提出了风吹雪区划的理论、原则、要求和区划单位系统、指标及方法。据此,把中国风吹雪区划分为2 个区域、3 个大区、13 个地带、39 个地区和131 个区,使其更加显示出专门区划的特色

The snowdrift, which blocks some roads with much drifted snow, occurs easily under the condition of low temperature with storm wind in Heilongjiang Province although there is no much snow there in winter. The drifted snow metamorphoses to a very hard layer, named hard depth hoar. Another traffic-blocking factor in mountain areas is the aufeis. The ice thickness grows intermittently at each position of the aufeis because the sprung water flows and freezes alternately at positions. As the economy develops and...

The snowdrift, which blocks some roads with much drifted snow, occurs easily under the condition of low temperature with storm wind in Heilongjiang Province although there is no much snow there in winter. The drifted snow metamorphoses to a very hard layer, named hard depth hoar. Another traffic-blocking factor in mountain areas is the aufeis. The ice thickness grows intermittently at each position of the aufeis because the sprung water flows and freezes alternately at positions. As the economy develops and the traffic increases, the normal snowfall would exert more and more influence on transportation, to which more attention should be paid. Therefore, for a disaster-relieving strategy, the use of antiskid tires (winter tires) should be gradually popularized, and a better system for snow and ice clearing and road maintenance, together with some necessary engineering projects, should be developed.

黑龙江省冬季降雪不多,但在寒冷和强风条件下,容易产生风吹雪,使某些地点形成较深的积雪,阻塞交通。风吹堆积下的积雪在低温下形成密实坚硬的硬深霜。涎流冰是冬季影响山区交通的另一个主要因素,它的各个部位呈现出间歇性增厚的特征,是涌出水在各处反复交替流动、冻结的结果。随着经济发展,交通流量增加,正常降雪将会产生越来越大的影响和危害,必须给予足够的重视。因此,在雪冰减灾战略对策上,应逐步推广使用防滑汽车轮胎,建立较为完善的公路雪冰清除服务体系,并辅以必要的工程措施。
