| 3. | Surface ocean - low atmosphere study 低层大气科学研究计划 |
| 4. | Using the doppler principle , low level winds are determined from the speed and direction of the movement of the eddies 运用多普勒原理,低层大气的风向和风速可从上述湍涡的移动方向和速度计算出来。 |
| 5. | Eventually atmospheric drag removes them from orbit by lowering their altitudes until they burn up on reentry into the dense lower atmosphere 最终空气阻力会使它们高度降低、移出轨道,在重返地表的过程中,被浓密的低层大气燃烧殆尽。 |
| 6. | A sensitive experiment is also performed to prove that dynamical instability of low level atmosphere would strengthen the entrainment of the sand particles in surface 最后本文通过动力稳定性对起沙影响的敏感性试验证明了低层大气的动力不稳定能增强起沙。 |
| 7. | Wind - field diagnostic analysis and historical observation data are used to reveal general flow patterns of lower atmosphere over beijing area 用风场诊断方法和实际观测资料对北京地区低层大气的背景流动情况进行分析,获取当地流动时空演变的总体型式或模态。 |
| 8. | The mesoscale circulation determines basic air flow patterns in this area , which is typical in spring - summer season and in calm weather of autumn - winter season 中尺度环流是该地区低层大气流动的基本模态,春夏季和秋冬季弱系统条件下的区域流动大体按这种模态演变。 |

| 10. | Such results are gotten : due to the unique topography the wind of beijing area during the day time is southern anabatic wind and in the night is northern katabatic wind in summer 研究结果表明: 1北京区域夏季边界层风场受西北特殊地形的影响,夜间低层大气流场常表现为由北向南的下坡风,白天逐渐转为由南往北的上坡风。 |
