  snowmelt process
The California water system is especially vulnerable to global warming due to its dependence on mountain snow accumulation and the snowmelt process.
      
A simulation of the annual variation of temperature and moisture in the atmosphere and sublayer of soil in mid-high latitudes has been performed with a one-dimensional atmosphere-land coupled model, in which snowmelt process is included.
      


Based on the data taken from the Tianshan Snowcover and Avalanche Station. Academia Sinica, the authors studied the relationship among the depth of meltsnow, average wind velocity, integral value of positive air temperature at the height of 1. 5m above the snow surface, and gave linear formulas for them. The authors emphasized the special influence of snow albedo on the snowmelt process and pointed out a positive feedback mechanism.

The impact of climate change on the river runoff of the international rivers in northeastern China was as-sessed by a monthly water balance model. It is found that the snowmelt process is difficult to simulate, but the calibration and validation result was satisfactory and it was applied to evaluate the response of river runoff to the climate change produced by several GCM models (GFDL, GISS, LLNL, MPI and OSU) . The annualrunoff is changed by - 3.72% to 5.82% , and seasonal variation is even greater.

利用流域月径流模型分析气候变化对东北国际河流的定量影响。对黑龙江流域边境地区典型子流域呼玛河和绥芬河流域进行月径流模拟计算。应用建立的径流模型分析了气候变化情景下天然径流的可能响应。计算结果表明,在5种大气环流模式给出的二氧化碳浓度倍增条件(2030年)的气候变化情景下,由于气温、降水的变化,多年平均径流将增加或减少,幅度在-3.72%至+5.81%之间。

In this paper the changing trends of monthly precipitation over China during the last 50 years are analyzed based on the long-term precipitation data at 678 meteorological stations in China, and the response of river runoff to climate change are also analyzed based on the monthly runoff data at the main hydrological stations of the Yellow River, the Yangtze River and the Songhua River/Amur River by using the linear regression methodology.

In this paper the changing trends of monthly precipitation over China during the last 50 years are analyzed based on the long-term precipitation data at 678 meteorological stations in China, and the response of river runoff to climate change are also analyzed based on the monthly runoff data at the main hydrological stations of the Yellow River, the Yangtze River and the Songhua River/Amur River by using the linear regression methodology. It is found that the monthly variation of precipitation demonstrates an obvious region-dependence. A generally decreasing trend is mainly in the eastern region of China from August to December, and an increasing trend is in South China from January to March. The contradiction between water supply and demand during fall and winter becomes more and more serious owing to the obvious decrease of river runoff in the dry season caused by the uneven change in precipitation within one year, and especially because of the constant decrease of precipitation from August to December, and the discharge increase due to increase in precipitation in flood period lead to more floods. In addition, the earlier snowmelt process in the spring due to warming climate in the upper Yangtze River and the Yellow River, originated all from the Tibetan Plateau, leads to an increase of runoff in the two rivers in snowmelt period. The long-term trends in discharge at the control stations in the three rivers during 1951_1998 show positive from January to April, but negative from June to December, except for an increasing trend in discharge at Datong station in the lower Yangtze River in July, at Tangnag Station in the upper Yellow River in June and at Harbin Station in the Songhua River in August. This is caused by precipitation change, earlier snowmelt due to global warming, and human activities such as irrigation and regulation of hydropower stations.

应用全国范围内的678个气象站1951—1998年长系列逐月降水资料, 用线性回归方法研究降水量的变化趋势, 同时结合长江、黄河和松花江主要控制水文站同期的径流资料, 研究径流对气候变化的响应. 结果表明: 降水的年内变化表现出较大的区域特性, 最显著的变化特点是秋冬季 (8~12月) 东部地区降水量普遍减少, 1~3月江南地区降水有增加趋势. 气候的上述变化趋势对我国干旱的西北地区有利, 该区河流径流量有明显增加; 另一方面, 夏季降水的增加可能会导致洪水事件的濒发,与此同时, 降水量的年内不均匀变化, 特别是在 8~12 月长时间的降水减少趋势, 导致枯水期径流的减少, 从而加剧秋冬季水资源的供需矛盾. 长江、黄河和松花江主要控制水文站6个站 1~4 月径流基本上表现为增加趋势, 而6~12月大多表现为减少趋势, 只有黄河上游唐乃亥站 6 月, 长江下游大通站7月和松花江哈尔滨站8月径流为增加; 另外, 气候变暖使发源于青藏高原的长江(宜昌站 3、4 月)和黄河上游(唐乃亥站4~6月)的春季的融雪过程提前, 融雪期径流增加.
