摘要
This paper summarizes the results and findings from the first International Workshop on Satellite Analyses of Tropical Cyclones(IWSATC).Estimating tropical cyclone intensity in the absence of penetrating reconnaissance aircraft is mainly left to satellite-based remote sensing methods.The primary method used globally since the latter part of the last century is the Dvorak Technique.While this method has withstood the test of time,it is not without limitations,and has been subject to regional modifications by various national tropical cyclone analysis centers.Differences between agencies in both the application of the Dvorak Technique and in general operational procedures to derive final intensity estimates can lead to real-time warning conflicts,as well as issues with final best track values for climatological analyses.As coastal populations increase,the WMO recognizes these issues as potentially serious problems,and organized a workshop in 2011 to bring together tropical cyclone experts to 1) discuss current operational analysis practices,2) learn about developing satellite techniques,and 3) come up with a set of recommendations to start down a path towards a global congruence on intensity estimation procedures.
