| 1. | 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 |
| 2. | 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。 |
| 3. | 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。 |
| 4. | It s a high voltage area
这是高压区 |
| 5. | 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？ |
| 6. | 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。 |
| 7. | 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。 |
| 8. | 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。 |
| 9. | 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。 |
| 10. | 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 |
