Three Dimensional Analysis of a Tropical Cumulonimbus Cloud over the Malayan Peninsula

[摘要] A tropical cumulonimbus cloud over the Malayan Peninsula was studied by means of the stereophotogrammetry. After three dimensional analysis of the cloud, the following results were obtained :1) Intermittent updrafts in Cb clouds developed into a petal like form and a hole was observed at the top.2) An anticyclonical sucking action by the cumulonimbus cloud was observed at an altitude of 4 to 5km, that is, just above the level of low cumulus cloud.
