Please analyze the main factors that form the wonders of Huangshan sea of clouds.

A. Huangshan is rich in water vapor. Huangshan is located in the southwest of the middle and lower reaches of the Yangtze River, adjacent to the mouth of Qiantang River in the east, and the warm and humid airflow from the Pacific Ocean can reach Huangshan directly. B. Huangshan mountain peaks are towering, and the warm and humid airflow is blocked. When it rises along the slope, it has a fierce convection with cold air, and when it condenses, it forms water and clouds, causing rainfall. C. There are many lakes and waterfalls in Huangshan and its surrounding areas, and the vegetation on the mountain is dense, which can store a lot of precipitation. At the same time, water surface evaporation and vegetation transpiration provide a large amount of water vapor supply for the local atmosphere.
