英文摘要 | There remains no consensus on whether the outer size of the tropical cyclone wind field impacts tornado occurrence. This study statistically examines the relationship between tropical cyclone outer size with both the number and location of tornadoes using multidecadal tornado reports, a reanalysis-derived tropical cyclone outer size metric, and radiosonde data. These results show that larger tropical cyclones spawn tornadoes that are located farther from and over a broader region relative to the cyclone center, although these changes do not entirely scale with TC outer size. Larger tropical cyclones are also associated with more frequent occurrence of tornadoes per 6 h, especially enhanced numbers of tornadoes. These changes in tornado occurrence in larger TCs may be due to a broadening of favorable helicity for tornadoes in the downshear sector, which may be partially offset by CAPE reductions in the left-of-shear quadrants. |
