Visualization of the 3-Dimensional Structure of Clouds and Water Vapor in the Hurricane Environment
Recent developments in satellite remote sensing include the Hyperspectral Atmospheric Infrared Sounder (AIRS) aboard the Aqua satellite that measures upwelling Earth-emitted infrared spectra using more than 2300 IR channels between 3.7 and 15.4 microns. UW CIMSS has developed a retrieval package for satellite derived water vapor products. The CSPP Dual Regression algorithm generates 3-Dimensional water vapor fields from the AIRS IR channels. Likewise, the UW CIMSS cloud amount vertical profile (CAVP) consists of a 3-D volume of cloud amount within the AIRS granule (135 x 90 x 54). SSEC/CIMSS McIDAS-V is software developed by SSEC/CIMSS to be able to visualize and analyze satellite data in 2-D and 3-D.
Case studies are presented from the Pacific Typhoon Ioke in 2006, Atlantic hurricanes Nadine and Sandy in 2012, and an example from the 2013 Atlantic hurricane season. Using the McIDAS-V software we will illustrate the synergistic relationship between water vapor fluxes and convective cloud formations in 3-Dimensional animations. With this new data and visualization we are able to compare the storms to older data from all sorts of procedures. We also are now able to see into the storm and see the inner workings of a hurricane while characterizing the environmental conditions which control the storm development.
