A global atlas of tropical precipitation extremes

Research output: Chapter in Book/Report/Conference proceedingChapter


Record rain events in 1998-2016, for 27-hour and 75-hour periods and on spatial grids from 0.25 to 4degrees spacing, are offered in a clickable online atlas. Events are based on the Tropical Rainfall Measuring Mission 3B42 rainfall data. One case is illustrated here. Selecting any location on the atlas creates a small script that users can open into a detailed case study. Case study resources include meteorological analyses in standard bundles of data+displays that draw from large online reanalysis and satellite data aggregations. Multisource comparisons of 1-degree daily rainfall estimates also help bracket rainfall data uncertainties. The example here is a nearshore Bay of Bengal event in June 2006 associated with a developing mid-level monsoon cyclone. Its adequate analysis in the Modern-Era Retrospective analysis for Research and Applications, version 2 allows a dynamical discussion. If similar efforts (and deeper work such as modeling) can be made easy enough, many more cases from this atlas could be assembled into improved knowledge of the nature of extreme rain events more generally.
