| Outline of Final Research Achievements |
In this work, an algorithm to derive large-scale mean tropospheric updraft using satellite measurements such as temperature and humidity soundings in order to construct a dataset for use by a range of future studies of the tropical atmospheric circulation. A variety of satellites carrying hyperspectral infrared sounders and radars are analyzed to evaluate the atmospheric vertical motion on the basis of thermodynamic budget analysis. The estimations are confirmed to be consistent with the existing ground measurements of vertical velocity. In addition, a methodology was tested to quantify the contribution of cumulus mass flux to the driving mechanism of atmospheric circulation, which has opened a new pathway for future investigations.
