| 摘要: |
| 利用"2000年南海海气通量观测"项目现场观测的辐射资料分析了南海季风爆发前后南海太阳总辐射、海面反射辐射、大气长波辐射、海面长波辐射、净余辐射的日变化和逐日变化规律的实际事实。结果表明,季风爆发前后、云系增多云层增厚,对太阳总辐射、海面反射辐射、海洋和大气长波辐射均有显著的影响。季风爆发期间产生的大浪对海面反射辐射、洋面反射率影响很大,可导致两者的强度急剧增加。 |

| Abstract: |
| In this article, the diurnal and day to day variation of solar total radiation, upward solar radiation, downwelling long-wave radiation, upwelling long-wave radiation and net radiation budget in South China Sea during May and July before and after South China sea monsoon onset have been analyzed, using the radiation observation data of "South China Sea Sea-Air Flux Measurements During 2000" project The analysis results show, before and after monsoon onset, nephsystem increasing and cloud layer thickening have remarkable effect on total solar radiation, upward solar radiation, downwelling long-wave radiation and upwelling long-wave radiation. During monsoon onset, the great wave caused by monsoon have much effect on upward solar radiation and reflectivity of sea surface and can cause the strength of upward solar radiation and the reflectivity of sea surface to increase rapidly. |
