摘要
根据球形粒子的Mie散射理论和平行平面大气中的辐射传输理论分析了作用于水云粒子的太阳辐射压力。结果表明,一般情况下当云滴半径不大于10μm时,太阳辐射压力可达云滴重力的百分之几;云滴半径在0.3μm附近时,太阳辐射压力达到极大值,约为云滴重力的百分之几十。因此在云物理研究中应考虑作用于云粒子的太阳辐射压力。
The solar radiation pressure on water cloud particles is analyzed with Mie scattering theory and the two stream radiative transfer method.It is found that this pressure can generally be some percents of the gravity on the particle whose radius is less than 10 μm,and that for a particle with radius about 0.3 μm,the pressure reaches the maximum and can be some tens percents of the gravity.Therefore the solar radiation pressure must be taken into consideration in the studies in cloud physics.
