| 摘要: |
| 用一个含植被参数化的二维中尺度模式研究青海湖夏季的湖陆风,模拟结果再次表明该模式具有重现局地中尺度环境特征,如冷(热)岛环境和湿岛等。同时表明,模式对植被覆盖度是敏感的,即有稀疏植被覆盖(δ=30%)情况的湖陆风白天比裸地情况要小,夜间则大,湖岸水平温度(或湿度)梯度随植被覆盖度增加而减小。 |

| Abstract: |
| A 2-D mesoscale model including a vegetative land breeze of Qinghai Lake during summer and a eterization is lased to study the lake-ad breeze is again simulated 9 thereby confirming the ability of the model to reproduce the known properties of this local mesoscale circulation, such as cold (heat) island circulation and wet island. The results show that this model is sensitive to changes in the vegetative cover, namely, the lake-land breeze with shore covered by sparse vegetation (δ=30%) is smaller (grenter) than that at daytime (night) in the case of bare shore. It is also shown that the horizontal temperature (or humidity) gradient is decreased when the vegetative cover is increased. |
