| 摘 要： | 利用热扩散型云凝结核计数器在贺兰山地区进行地面和空中云凝结核(CCN)观测。结果表明,在该地区夏季地面平均CCN浓度为610 cm-3,最大浓度达104 cm-3。沙尘天气现象没有明显地增加CCN浓度。层状云中CCN浓度随高度变化不大。

| Abstract: | The concentration of cloud condensation nuclei is determined from surface and aircraft measurements at Mt. Helanshan area. Tests were performed using a horizontal thermal diffusion chamber from 1994 to 1995. The results show the mean values of concentrations are 610 cm {-3} at supersaturation of 0^5% at ground level. The CCN concentration almost do not change with altitudes in stratus cloud over Ningxia area. The resource of sand and dust particles has little influence on the CCN concentrations. |
