摘要
通过使用小气候自动观测仪对天山北坡四工河流域进行的对比观测分析,得出以下结论:山风平均风速大于谷风1ms/以上;谷风周期要明显长于山风周期;山谷风的转换期风向紊乱,风速较小,甚至表现为零;山谷风在强天气系统的背景下表现微乎其微;山谷风环流对保持山区的热量平衡具有重要的作用。
The contrast observation analysis on Four Work River valley of Tianshan Mountains have obtained following conclusions using automatical microclimate recorderthe average mountain breezes velocity was 1m/s stronger than the valley breezesthe valley breezes period was obvious longer than mountain breezes in breezes direction conversion period breezes direction were chaoticthe velocity was smallereven for zerothere were little or nothing the breeze when prevailing strong weatherthey were important to maintain heat balance of mountain area.
