Is high-altitude geomantic omen contrary to ground wind?
Sea-land wind: Because the specific heat of land is less than that of ocean, when the temperature rises in daytime, the land heats up faster than the ocean, forming land updraft, ocean downdraft, near-surface low pressure and near-surface high pressure, and sea breeze blows from the ocean to near-surface land; When the temperature drops at night, the land cools faster than the ocean, forming a downward airflow on the land, an upward airflow on the ocean, a high pressure on the land near the ground, and a low pressure on the ocean near the ground. The land wind blows from the land to the ocean near the ground.
Urban wind: Because the temperature in the city is higher than that in the suburbs, the air pressure in the urban area is low, the air flow in the suburbs is downward, the air pressure in the suburbs is high, and the wind blows from the suburbs to the urban area. (Unlike the land and sea breeze, the city breeze has no seasonal change, and the four monsoon directions are the same. )
(Whether it is land-based wind or urban wind, it refers to the wind near the ground, and the wind direction of high-altitude wind is opposite to that near the ground. )
