Air descends in high pressure area and rises in low pressure area 空气在高压区下降,在低压区上升
Hence , a high pressure area usually has fine and dry weather 所以高压区的天气通常比较乾燥和良好的。

It s a high voltage area 这是高压区
Why is bad weather usually associated with low pressure and good weather with high pressure 为什么低压区的天气通常比较坏而高压区的天气通常比较好?
In contrast , in an area of high pressure , the air at low levels spreads outward and air descends from aloft 相反,在高压区内空气往外扩散,逼使上面的空气下沉。

Cyclones and anti - cyclones in the upper air are often associated with low and high pressure areas on the surface 高空的气旋和反气旋,往往与地面的低压区和高压区有密切的关系。
Usually , areas of relatively high or low geopotential correspond with areas of high pressure or low pressure respectively 同时,位势相对较高及较低的区域,亦与高压区及低压区互相呼应。
If the pressure changes over a large area , winds start to blow in a huge circle . high - pressure air is pulled into a low - pressure center 如果压力大范围的改变,风就开始围绕一个大的圆圈回旋,高压区的空气被推进低压中心
