| Summary: | YAN, TINGZHUANG. Interannual variability of climatology and tropical cyclone tracks in North Atlantic and Western North Pacific. (Under the direction of Lian Xie.) The spatial-temporal variability of tropical cyclone tracks and their possible association with tropical cyclone landfall frequency along the United States East Coast and China East Coast are studied using Principle Component Analysis of tropical cyclone Track Density Function (TDF). Results show that North Atlantic (NA) hurricane TDF is strongly modulated by El Niño-South Oscillation, the tropical Atlantic SST dipole Mode (DM), North Atlantic Oscillation and Arctic Oscillation. Dominant Modes of Western North Pacific (WNP) typhoon TDF demonstrate strong correlation with spring and winter snow cover (SC) over the Qinghai and Tibetan Plateau (QTP). Results provide a foundation for the construction of statistical models, which project the annual number of tropical cyclone landfall along the East Coast of the United States and the coast of China. Analysis for 1990 and 2004 NA hurricane seasons revealed that the substantial variability of tropical Atlantic SST DM is a dominate factor affecting the hurricane track patterns. |
