As a complementary study to Lonfat et al. (2004) and Chen et al. (2006), this study will not only quantify the TC rainfall wavenumber-1 asymmetry, but also the contributions to asymmetry from wavenumbers 2 through 6. Using the Fourier wavenumber decomposition method, the goal is to understand how rainfall asymmetries respond to varying storm motion and environmental vertical wind shear for different intensity storms in different basins. Sixteen years (1998-2013) of TRMM Microwave Imager (TMI) data, totaling 3542 TMI overpasses of TCs, will be used. Composite results will show wavenumber-1 and wavenumber-2 through -6 asymmetries for total, light, moderate, and heavy rainfall distributions in six TC-prone basins including Atlantic Ocean, East Pacific Ocean, Northwest Pacific Ocean, North Indian Ocean, South Indian Ocean, and South Pacific Ocean. The analysis will differentiate intensity categories with slow motion, fast motion, weak shear, moderate shear, and strong shear. According to shear and motion directions, TC overpasses will also be categorized into four categories including that the shear direction is same to, opposite to, to the left of, and to the right of motion direction. Both shear-relative and motion relative composites will be examined.
