The reasons for the formation of sea fog are divided into three situations.

Sea fog was a kind of fog that appeared in the ocean or coastal areas, often accompanied by a unique scene and flavor. There were many reasons for the formation of sea fog, including the following three situations: 1. Cold current sea fog: When the warm and humid airflow enters the depths of the sea, the water molecules in the sea will condense into small water droplets due to the drop in temperature. These small water droplets will float in the sea and form cold current sea fog. This kind of sea fog usually appears around sunrise, because after the sun rises, the warm and humid airflow will make the sea temperature rise, and the cold sea fog will also dissipate. 2. Warm current sea fog: When cold air enters the sea, the water molecules in the sea will condense into small water droplets due to the drop in temperature. These small water droplets will float in the sea and form warm current sea fog. This kind of sea fog usually appears around sunset because the sun sets at sunset, and the warm air currents will raise the temperature of the sea water, and the warm sea fog will dissipate. 3. Mixed flow sea fog: When the warm and humid airflow and cold air mix into the seawater, due to the large difference in temperature, the water molecules in the seawater will condense into small water droplets to form a mixed flow sea fog. This kind of sea fog usually appeared around sunrise or sunset. When the sun rose or set, the mixture of warm and humid air and cold air would cause the temperature of the sea to change, resulting in sea fog. There should be an introduction to the effects of the cold and warm currents on the sea fog in the geography humanities in high school. Generally speaking, the cold current would play an important role in the formation and transmission of the sea fog, while the warm current would have an impact on the formation and dissipation of the sea fog.
