According to relevant public information, the wind at Duchang Hydrological Station is lake wind during the day. When the precipitation during the day is more than that at night, it will form lake wind with the surrounding area.
When the sea breeze blows during the day and the sun shines during the day, the land and the ocean will absorb heat and heat up. The specific heat capacity of seawater is larger than that of the ground, and the temperature of the ground is much higher than that of the sea. The air above the land is relatively high, but the density is small and rising. The air above the sea surface will blow to the land to replenish it, forming a sea breeze, and both the land and the ocean will release heat and cool down at night. The specific heat capacity of seawater is larger than that of the ground, but the sea surface temperature drops less and the temperature is relatively high, while the air density above the sea surface
When the sea breeze blows during the day and the sun shines during the day, the land and the ocean will absorb heat and heat up. The specific heat capacity of seawater is larger than that of the ground, and the temperature of the ground is much higher than that of the sea. The temperature and density of the air above the land are relatively high, and the air above the sea surface will be blown to supplement the land and form a sea breeze.
At night, both land and sea release heat and cool down. The specific heat capacity of seawater is larger than that of the ground, and the sea surface temperature drops less, but the temperature is relatively high. The air density above the sea surface is small and rising, and the air above the land will be blown to the sea surface to supplement it, forming a land wind. The alternation time of land-sea breeze is related to local conditions and weather conditions. The wind blowing from the sea to the land during the day is called sea breeze, and the wind blowing from the land to the sea at night is called land breeze. The formation of land-sea breeze is caused by the different properties of ocean and land.
