近几个月以来，大气层持续的高压送走了美国中南部的暴风雨，却使得该地区变成了焦土，并使得美国其他地区遭受罕见的大雨。
In recent months, persistent ridges of high pressure have been driving storms away from the south central United States, leaving that region parched while drenching others with unusually heavy rain.
高压天气系统在把好天气以及晴朗天空带到美国的同时，也创造了这“大气层上的艺术”。
The high-pressure weather system that brought fair weather and relatively clear skies to the United States also created this atmospheric art.
当它在比以前更长的时间里保持不结冰的状态，它也会将更多的热量输入北极区的大气层，这就使北极区的气压变高，使冰岛低压和亚速尔高压之间的梯度变小。
As it remained clear for longer than usual it also bled more heat into the Arctic atmosphere. This caused higher air pressures, reducing the gradient between the Iceland low and the Azores high.
