Focusing on the contradiction between the statement that "valley wind speed is higher than mountain wind speed" in high school geography textbooks, and the content of geography academic profi ciency tests as well as actual observation data, this paper conducts relevant research. Through multi-scenario analysis based on AI models, field observation and literature data, it discusses the complex infl uencing mechanism of the wind speed diff erence between mountain and valley winds, and proposes that the characteristics of mountain-valley breeze should be comprehensively judged in combination with specifi c geographical environments.
