青藏高原积雪分布与变化特征

本文对青藏高原ＳＭＭＲ修积雪深度、ＮＯＡＡ周积雪面积、地面台站积雪深度进行了分析。结果表明青藏高原东西两侧多雪与腹地少雪形成鲜明对比,高原东部是高原积雪年际变化最显著的地区,它主导了整个高原积雪的年际变化,并且与西部多雪区年际波动呈反位相关系。从６０年代到８０年代积雪年际波动幅度有明显增加趋势,积雪变化具有３年左右准周期。随着全球变暖,青藏高原积雪将会有所增加。     

中国天山西部季节性森林积雪物理特性

积雪特殊的物理特性对冰雪水文过程、积雪生态系统、不同尺度的气候系统有重要影响。目前对林下积雪物理特性缺乏系统性研究,因此对天山雪岭云杉林下季节性积雪深度、沉降速率、密度和含水率进行观测分析。结果表明：林下积雪深度小于开阔地;林下积雪沉降速率和新雪密实化率小于开阔地,且稳定期沉降速率小于融雪期。稳定期林下积雪密度小于开阔地,林下雪层密度最大值位于中粒雪层,开阔地则位于粗粒雪层;融雪期则全层密度趋于一致。稳定期林下雪层含水率随深度递减,开阔地雪层最大值出现粗粒雪层;融雪期雪层汗水峰值出现在细粒雪层,新雪层最小,林下雪层由细粒雪层到深霜层始终呈减小趋势,开阔地雪层由细粒雪层至中粒雪层逐渐减小,粗粒雪层至深霜层逐渐增大;稳定期雪层含水率日变化随深度的递减逐渐减小,开阔地大于林下;开阔地的新雪层和细粒雪层含水率的日变化大于林下,粗粒雪层到深霜层则小于林下。     

季节性森林积雪融雪期雪层含水率垂直廓线与时间变化特征

利用snow fork雪特性分析仪测量天山积雪与雪崩研究站融雪期开阔地(站区内气象观测场)与雪岭云杉林下雪层含水率,分析季节性森林积雪融雪期雪层含水率垂直廓线和时间变化特征以及与气温的关系。结果表明:由于开阔地和林下积雪接受的太阳辐射、雪层密度和雪层污化程度等的不同,开阔地、树冠边缘及距树干1m处的雪层含水率垂直廓线特征、雪层含水率的日变化特征以及融雪期雪层含水率随时间的变化特征各异;雪层含水率受气温因子影响最大,融雪期雪层含水率随气温变化呈指数增加,由于开阔地和林下微气象条件的不同,三点雪层含水率对日均温、最高温、最低温、日较差以及逐时气温的响应也不同,且雪层含水率对气温的滞后效应也各异。     

乌鲁木齐河源雪密度观测研究

乌鲁木齐河源高山区积雪形成期(10月)积雪层的月平均密度为140kg/m~3,稳定积雪前期(11—2月)和稳定积雪后期(3—4月)雪层的月平均密度分别为190—210kg/m~3和175kg/m~3,非稳定积雪期(5—9月)的新雪密度介于90—125kg/m~3,平均值为112kg/m~3。统计分析表明,冬季积雪层的平均密度不随积雪深度而变化,但与5日平均气温和5日合计降水量呈反相关关系,夏季新雪的密度随雪深的增大而上升,风速对冬季积雪层平均密度和夏季新雪密度均无明显影响作用。     

中国天山西部山区森林积雪消融过程观测分析——以巩乃斯河谷为例

通过对2013年春季中国科学院天山积雪与雪崩研究站区内阳坡无林地和阴坡不同开阔度森林内积雪深度、融雪速率以及常规气象的观测,分析了融雪期不同开阔度森林积雪的消融过程以及积雪表面能量平衡特征。结果表明:不同开阔度林冠下积雪深度具有相同的变化趋势,森林的林冠开阔度越大,林下积雪深度越大,林下积雪开始消融和完全消融的时间越晚,消融期也越长。森林积雪融雪开始和结束时间比阳坡无林地区晚20~30 d左右。融雪前期林冠开阔度越大,其林下融雪速率越小。融雪后期则森林开阔度越大,森林积雪的融雪速率越大。不同时期由于不同开阔度林冠下雪面能量收支以及雪层深度等物理特性的差异,从而使不同开阔度林冠下森林积雪融雪速率的相对大小,融雪速率最大值出现时间和日变化特征均不相同。晴天森林积雪的消融速率和日变化特征取决于净短波辐射和长波辐射变化特征。降水期间,其融雪速率的变化则主要受降水形式、降水量以及积雪深度等雪层特性的影响。     

南极长城站积雪及其消融过程

南极长城站区稳定积雪期始于4月中至6月初,8月中至10月达最大深度。1988年沿海地带一般积雪深度为0.6～0.8m,低洼处及建筑物附近可达1.2～1.6m,甚至超过1.8m;潮汐带雪盖下部温度受海冰影响普遍偏低;11月底至来年1月初的消融过程中,积雪表层常常处于相变区,雪层底部温度比冰点低0.02℃,融水下渗形成雪盖下部潜流;积雪相态及其温度变化与大气-雪感热通量的变化过程相对应,大气-雪感热交换是积雪消融的重要因子之一。     

中国天山西部季节性森林积雪雪层温度时空分布特征

利用2009年12月27日～2010年4月2日天山积雪站站区内开阔地和雪岭云杉(Picea schrenkiana)林下6次降雪过程后雪层内时间间隔10 min的温度数据,探讨雪层温度变化特征。结果表明,越接近地表雪层温度越高,且在雪层表面形成冷中心和(局部)暖中心;在积雪稳定期林下雪层温度高于开阔地,融雪期林下低于开阔地;林下雪层冷、暖中心出现时间晚于开阔地,其强度也小于开阔地。林下雪层温度振幅小于开阔地,林下温度振幅拐点以上雪层温度振幅随深度和时间的递减率小于开阔地,拐点以下无明显差异。初冬,林下和开阔地雪层均为较小的正温度梯度,随着气温急剧下降,温度梯度逐渐增大,且从雪表向雪底递减,林下雪层负温度梯度出现时间晚于开阔地。开阔地和林下积雪表层正温度梯度最大值分别达到0.95℃/cm和0.82℃/cm,负温度梯度大值分别达到-0.84℃/cm和-0.35℃/cm;但开阔地全雪层日平均温度梯度小于林下雪层。     

水在非均质雪中的流动

一、引言研究和预测积雪覆盖地域上径流的形成是十分必要的。前人已对雪层中融水和雨水的运动问题做过细致的研究。本文给出在含有冰层和流槽的积雪中水的流动模式。对于雪特性空间变化的一切设计,它都是适用的。     

融雪期天山西部森林积雪表面能量平衡特征

通过对2013年春季中国科学院天山积雪与雪崩研究站站区内阳坡开阔地和阴坡雪岭云杉80%和20%开阔度林冠下气温、大气湿度、风速以及雪面短波和长波辐射的观测研究,分析了融雪期不同开阔度林冠下积雪表面能量平衡特征。结果表明:由于植被影响,阴坡雪岭云杉林冠下积雪表面净短波辐射和显热明显小于阳坡开阔地,但净长波辐射损失小于阳坡开阔地。阴坡林冠下积雪表面总能量明显小于阳坡开阔地,因此阴坡森林积雪融雪开始消融和结束时间明显晚于阳坡开阔地。在阴坡,林冠开阔度越大,雪面获得的净短波辐射和显热越大,但损失的净长波辐射和潜热也越大。不同开阔度林冠下和阳坡开阔地积雪表面的净短波辐射、显热和潜热有相同的日变化特征,但是森林积雪表面夜晚的显热和潜热多为0 W/m2;阴坡森林积雪表面长波辐射日变化特征明显不同于阳坡开阔地雪面。     

准噶尔盆地积雪储量的遥感反演及变化特征分析

利用被动微波遥感SSM/I亮温数据反演的积雪深度,采用积雪密度经验算法,计算了准噶尔盆地1987-2008年逐日雪储量及其分布状况。结果表明:(1)准噶尔盆地年最大雪储量22 a平均为4.53×109m3,最大年份为1994/1995年冬季,雪储量达7.13×109m3,最小年份为1995/1996年冬季,雪储量为2.74×109m3。(2)准噶尔盆地冬季雪储量空间分布不均匀,雪储量较大的区域分布在阿尔泰山南麓和天山北麓,且由盆地边缘向中心逐渐减少,两个明显的低值区分别位于盆地西部克拉玛依地区附近和盆地东部北沙窝附近。(3)季节内变化特征表现为:11月上旬至2月中旬为雪储量缓慢累积的过程,3月上旬雪储量达到峰值,持续时间很短(约15 d),3月中旬至4月下旬雪储量迅速消退,季节内变化主要受降雪和气温年内分配的影响。(4)1987-2008年准噶尔盆地雪储量的年际变化较大,65%的区域呈现线性增加趋势,但不显著。(5)冬季降水量和气温是影响雪储量变化的主要因素,雪储量与冬季降水量呈显著正相关,与气温呈显著负相关关系。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
