Based on the best-track dataset from Shanghai Typhoon Institute/China Meteorological Administration, paper provides a comprehensive summary and analysis of tropical cyclone (TC) activities in Western North Pacific (WNP) South China Sea (SCS) for 2022. Using historical climatology 1951 to 2020, anomalous conditions during 2022 TC frequency, origin locations, tracks, intensity, duration entire ocean basin as well landfall events are examined. Results show that overall frequency is slightly lower than normal, but multiple have very high occurrence. Origin locations TCs, which mark starting points their paths, large westward northward deviation climatology. Around 40% named TCs exhibit shift direction movement westerly easterly. Additionally, comparisons means, medians, upper quartiles all indicate intensity generally climatology, with at storm or above being shorter usual. A notable observation fewer incidence landfalls China, geographical concentration Guangdong Province. These annual influenced by related atmospheric oceanic environmental modulated multi-scale climate variability. The findings provide useful information enhancing disaster mitigation strategies Asia-Pacific region.
