Causes of sea fog formation in Tenerife Island

Sea surface temperature, sea temperature difference, airflow and wind field.

1, sea surface temperature: A large number of observation results confirm that advection fog mostly appears over the surface waters of Leng Hai. Especially in the waters where the sea surface temperature drops rapidly along the airflow direction, that is, on the cold water surface at the intersection of cold and warm airflow or in the land-sea boundary area with large horizontal temperature gradient, the warm and humid airflow moving over it is easier to denature and cool condensed water vapor, and fog is more frequent and common in these waters.

2. Sea-air temperature difference: The formation of advection fog depends not only on the condition that the surface water temperature is lower than a certain limit value, but also on the coordination between the surface water temperature and meteorological conditions, including the coordination between water temperature and air temperature.

3. Airflow wind field: The long-term existence of warm and humid airflow is very important for the generation and development of sea fog, which can continuously supplement a large amount of water vapor and heat necessary for fog formation. Therefore, in the zero generation, the southerly or easterly airflow is generally dominant. In China, the wind direction favorable for fog formation varies with the sea area. Generally speaking, fog is most common in the southerly winds in the East China Sea of China, and in the easterly winds in the South China Sea.
