Main reasons for wide sea ice range and thick ice layer in Liaodong Bay

(1) This paper briefly analyzes the main reasons for the wide sea ice range and thick ice layer in Liaodong Bay.

A, the latitude is higher than Bohai Bay and Laizhou Bay, and the temperature is lower in winter.

B, there are many beaches, sometimes affected by the Bohai tidal current system, and sea ice is easy to stay on the beach at the bottom of Liaodong Bay (the temperature is lower than the water temperature, which makes it easier to freeze).

C, because of its geographical location, it is more susceptible to the cold air on the north road than Bohai Bay and Laizhou Bay.

D, shallow seawater is a factor, but other bays are also shallow, so it is not special.

(2) Explain the harm of coastal sea ice in China.

Sea ice is a normal natural phenomenon. In recent years, with the large-scale construction of coastal engineering, the hydrodynamic environment in the ice area has been artificially changed, the climate anomaly has intensified, and the loss of sea ice disasters has increased. It is mainly reflected in the impact on navigation channels and aquaculture, and more far-reaching is the interference on resource transportation industries such as transporting coal from North to South.
