Outline of Final Research Achievements

Roles of cumulonimbus for transportation of substances, such as water vapor, from troposphere into stratosphere are not known since its observation is too dangerous to implement. Our research goal is thus estimate of the substance budget by use of satellites data.
The different characteristics of cumulonimbus by using different sensors were compared. We found temperature at the cumulonimbus top is variable even for one minute due to strong updraft. These results were published in the international journals. Through these studies, our results also imply that a cloud generated from cumulonimbus, which is not known even among Japanese MET society, may effectively transport the substances from troposphere to stratosphere. This cloud is the target of our future research.
