Low‐frequency snow changes over the Tibetan Plateau

摘要

ABSTRACT >Snow change over the Tibetan Plateau may exert a large influence on climate variability in the surrounding regions. However, the characteristics of snow changes at different time scales and the factors for these changes are still not clear. The present study documents linear trends in snow cover and snow water equivalent over the Tibetan Plateau and their relationship to surface air temperature changes during 1979–2006 based on satellite data. The long‐term snow variations display a remarkable regional difference and an obvious seasonal dependence. A significant decreasing trend is observed in the western part for snow cover and snow water equivalent in summer and fall and in the southern part for snow cover in all the four seasons. A significant increasing trend is identified in the central‐eastern part for snow cover in fall, winter, and spring and in the eastern and far western parts for snow water equivalent in winter and spring. The relationship between snow and surface air temperature changes features regional disparity. The temperature increase is accompanied by snow cover decrease in the southern and western parts, but by snow cover and snow water equivalent increase in the central‐eastern part. The reasons for the snow changes vary with the season. The increase in snowmelt following the temperature increase may be the reason for the snow cover decrease in the western and southern parts in summer. The snowfall change induced by vertical motion change appears to be a factor for the snow water equivalent increase in the far western part and the snow cover decrease in the southern part in winter. The increase in snowfall induced by the increase in atmospheric moisture following the temperature increase and the enhanced upward motion may contribute to the snow increase in the eastern part in winter. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden"

>藏高平台上的雪变化可能会发挥a对周围地区气候变异性的大量影响。然而，在不同时间尺度的雪变化的特点以及这些变化的因素仍然不明确。本研究文件在1979 - 2006年基于卫星数据期间，在藏高平台上的雪覆盖和雪水中的线性趋势和与地表空气温度变化的关系。长期雪变化显示出显着的区域差异和明显的季节性依赖。西部的雪覆盖和雪水在夏季和秋季和南部的雪水和南部的雪覆盖的雪覆盖中的雪覆盖。在秋季，冬季和春季以及东部和远西部冬季和春季的雪水中的雪覆盖中央东部的中央东部的显着增加的趋势。雪和表面空气温度变化的关系具有区域差异。温度升高伴随着南部和西部的雪覆盖减少，但通过雪覆盖和中央东部的雪水等效增加。雪变化的原因随着季节而变化。温度升高之后的雪姆的增加可能是夏季西部和南部部分雪覆盖减少的原因。垂直运动变化引起的降雪变化似乎是远方西部的雪水等同于雪水的因素，冬季南部的雪覆盖减少。温度升高和增强向上运动后大气水分增加引起的降雪量可能有助于冬季东部的雪增加。</
