| Research Abstract |
In order to increase the accuracy of numerical predictions of climate change, it is of importance to clarify the mechanism of energy transfer from sun though clouds and aerosols in atmospheric turbulence and to precisely model it. In this study, we clarified the effects of droplet(i. e. cloud droplet) evaporation and temperature difference between droplet and ambient air on the drag force and wake structure behind droplet, and the effects of turbulence on the solar radiation, namely transmittance, reflectance and absorptance in clouds, in terms of lab-scale experiments and numerical simulations.
