麦金太尔说，自上世纪30年代以来，导致该州水资源紧张的最大因素是气温上升导致树木向空气中流失更多的水分，提早的融雪减少了树木在旱季的供水。

Since the 1930s , McIntyre said , the biggest factors driving up water stress in the state have been rising temperatures , which cause trees to lose more water to the air , and earlier snowmelt , which reduces the water supply available to trees during the dry season ．

旱季土壤为热源而雨季为热汇，表层土壤年总热通量为-0.44MJ·m-2，说明就全年尺度而言，土壤是热源。

In dry seasons , the soil was a heat source , however , it was a heat sink in rainy seasons . The total surface soil heat flux was -0.44 MJ · m-2 per year , indicating that the soil was a heat source at the annual temporal scale .
