雲裳集 ── 雨幡洞 ﹝fallstreak hole﹞

── A fallstreak hole in Cirrocumulus (top left of the photo) spotted at dusk on 21-DEC-2010. So unfortunate that a portion of the fallstreak hole was not seen as the view was blocked by buildings (cut from photo).

雲裳集 ── 濃密雜亂狀卷雲 ﹝Cirrus spissatus intortus﹞

── Cirrus spissatus intortus spotted around 1300H, 14-AUG-2011. The photo has been post-processed for perspective adjustment. Note the black dot in the photo near the right edge at around 5/6 of its height. A magnified view of the photo shows that it is an aircraft in the air. Through this aircraft, the size of the cloud is visualized.

── Half an hour later, grown to this size and matured into a Cumulonimbus. The hairy feature on the top is an indication of its ice constituent.

雲裳集 ── 斷飛機雲

這張相大概於兩個星期前拍的：


某天日暮時份，我透過房間向西的窗見到的景象。

由於相機長時間沒有電，日期被重設至 2009 年 1 月 1 日，拍攝前未及修改，之後相片一直貯於 SIM 卡中，如今拍攝日期已無從稽考。
