The relationship between the intensity of summer storms in the South China Sea and the temperature difference between the air and sea in tropical oceans was studied. Data from two sources were analyzed, showing a strong connection between air-sea temperature difference and storm intensity in certain regions. The correlation is more stable over long periods of time, with variations in shorter time scales related to temperature differences in specific areas. Changes in atmospheric circulation patterns have also influenced the strength of the monsoon storms. Since the late 1970s, winds from the Southern Hemisphere have intensified in the lower atmosphere, while the South Asian high pressure system and winds from the Northern Hemisphere have strengthened in the upper atmosphere, leading to more intense summer storms in the South China Sea.
