Super Typhoons Hato (2017) and Mangkhut (2018) have disastrous impacts on the Philippines and South China. Their evolutions and consequences have received wide attention from various media and parties, while the relevant researches are yet limited. Here, we give a full review and comparison of Hato and Mangkhut in terms of their movement, intensity, sizes, and precipitation, targeting to advance the understanding of landfalling super typhoons and to help tropical cyclone forecasting ultimately, especially those over South China. In addition, astoundingly, we reveal that the occurrence of landfalling super typhoons in South China is evidently increasing and tropical cyclones in the northern part of the South China Sea are getting stronger. This study serves as a wake-up call that the threats caused by the tropical cyclones in South China become and may become more catastrophic and frequent in the warming climate.
