Abstract

We have been working at the large scale shaft in Hokkaido/Iwate to simulate the quasi-real scale cloud formation process using the cloud experiment facilities with various atmosphere conditions. We recorded the cloud formation process, phase change from the water vapor to the cloud particles under partial saturation, lapse rate of temperature and the change in the lapse rate of temperature in the cloud form the experiment since 1992, in total 16times. We obtained many outcomes from the experiments which would be never available from the small scale experiments and the real field observations. This study shows the time and scale variation between the particle concentration and the total water in the cloud.
