| 5. | Mean 500 hpa geopotential height for july 2002 . the red arrow shows the direction of the steering flow for tropical cyclones 二零零二年七月500百帕斯卡的平均位势高度,红色箭咀为热带气旋引导气流的方向。 |
| 6. | Mean 500 hpa geopotential height for the months of july from 1961 to 1990 . the red arrow shows the direction of the steering flow for tropical cyclones 一九六一至一九九零年七月份500百帕斯卡的平均位势高度,红色箭咀为热带气旋引导气流的方向。 |
| 7. | From 500 - hpa geopotential height maps , one can depict important weather systems on the large scale , e . g . subtropical ridge or long - wave troughs in the westerlies 从500百帕斯卡的位势高度图,可清楚检视大尺度的重要天气系统,例如西风长波槽或副热带高压脊等等。 |
| 8. | Geopotential , or gravitational potential relative to mean sea level , is the energy an air parcel may potentially acquire by virtue of its position in the gravitational field of the earth 位势高度位势,又称重力位势,是空气在地球重力场中蕴藏的能量。在大气中,位势会随高度和纬度而变化。 |
| 9. | For the sake of atmospheric analysis , geopotential is commonly converted ( namely , divided by the standard acceleration due to gravity ) to geopotential height and expressed in units of geopotential metre 为方便大气分析,一般会再把位势转换(除以重力常数)成位势高度,单位由能量变成高度,以位势米表示。 |
