Support for Prof. R. Elsberry was provided by the Office of Naval Research Marine Meteorology section. Dr. Karl Pfeiffer and Dr. Zhuo Wang have been very helpful in the code work development for data analysis. The authors gratefully acknowledge the ECMWF for the provision of the YOTC dataset (http://data-portal.ecmwf.int/data/d/ yotc_od/); the TRMM mission scientists and associated NASA personnel for the production of the TRMM data and visualizations that were produced with the Giovanni online data system, which is developed and maintained by the NASA GES DISC (http:// gdata1.sci.gsfc.nasa.gov/daac-bin/G3/gui.cgi?instance_id=TRMM_3-Hourly); the NOAA/Air Resources Laboratory (ARL) for the provision of the HYSPLIT transport and dispersion model and the READY website (http://www.arl.noaa.gov/ready.php); and the NOAA/NESDIS/Center for Satellite Applications and Research for the provision of the QuikSCAT data from their web site (http://manati.orbit.nesdis.noaa.gov/datasets/ QuikSCATData.php). This study benefited from the comments and suggestions of the anonymous reviewers. Mrs. Penny Jones provided assistance in the manuscript preparation.
