Summary:

Using the filter-paper technique, the raindrop size-sampling was conducted. The change in drop-size distribution of rain is affected by wind shear, gravity separation, evaporation and drop collision. To eliminate the evaporation problem, sampling was conducted for all the orographic rain at cloud base or within the cloud itself. In general, the higher the intensity, the more numerous are the drops at the large end of the spectrum. At the small end of the drop spectrum (< 0.4 mm), however, increased intensity is accompanied by decrease in the drop count. All of the drop distributions have been put into three categpories: non-orographic rain, orographic rain at cloud base, and orographic rain within the cloud and near cloud top.
