| 摘 要： | 在夜间灯光很弱或者没有灯光、星光、月光的情况下,云的目测是比较困难的。常规夜间观测云的方法是,根据视觉,结合星光疏密、空气清晰程度、云体的颜色、移动速度以及伴见的天气现象和实测云高,参照傍晚时云的状况来判别云状。为了能够在夜间快速准确地识别所在测站云状,以现代化探测设备为手段,对夜间云的观测方法进行了总结,介绍了用大气辐射、大气电场、气象卫星云图、多普勒天气雷达回波资料来辅助观云,可较好地弥补夜间目测云的不足。 |

| Abstract: | It is always difficult to observe clouds at night with the naked eye when there is no light, starlight or moonlight. The routine cloud observation at night is to observe clouds in accordance with the observer＇s vision in combination with the density of starlight, air clarity, cloud color and movement speed, weather phenomena and measured cloud height, as well as the observation of cloud condition at dusk. In order to identify the cloud condition at the located meteorological station rapidly and accurately at night, an introduction is made to the application of advanced apparatuses in assisting cloud observation, such as the data of atmospheric radiation, atmospheric electric field, meteorological satellite cloud pictures, and Doppler weather radar echoes, which can better cover the shortages in cloud observation during night time with the naked eye. |
| Keywords: | cloud observation at night radiation electric field satellite image radar echo |
