查询词典 precipitation

But there was exception in some regions with relative wet climate, such as southern Europe, southwest America. The wetter climate in these regions were contributed to strong cold high pressure systems over the ice sheets which forced westerlies shift southward and brought more precipitation and caused high lake level in these regions.

但也有一些地区例外，如欧洲南部和美国西南部由于受到大陆冰流反气旋控制，造成的西风带南迁而引起降水变化，湖泊反映出具有寒冷但潮湿的大湖或高湖面。

The established models in which annual precipitation was incorporated as the principal variable indicate a very closely correlation between forest productivity and its corresponding climatic factors,allowing to simulate distribution pattern of actual forest productivity effectiv...

结果表明：在所构建的模型中，除海拔高度与净生产力的相关模型外，其它模型均有较高的实用价值，模型的拟合曲线变化，基本反映了中国森林现实生产力的地理分布格局；中国森林生产力的分布格局主要取决于气候环境中的水热条件，水分条件是决定中国大部分地区森林生产力水平和地理分布格局的主导因素；根据7个GCMs大气环流模型预测合成的2030年的气候情景，研究气候变化对中国森林生产力影响的结果是：气候变化并没有改变中国森林第一性生产力的地理分布格局，即从东南向西北森林生产力递减趋势不变，但不同地域的森林生产力有不同程度的增加。
