Why is the land temperature lower than the ocean temperature in winter?

Analysis:

The mainland is colder than the ocean in winter and hotter than the ocean in summer, and the temperature difference between land and sea in the northern hemisphere is greater. This is because the specific heat of seawater is greater than that of land, so the warming and cooling of ocean is slower than that of land, and the cooling of land is faster than that of ocean in winter and faster than that of land in summer. On the east coast of the middle and low latitudes (the west coast of the mainland), the isotherm protrudes to the low latitudes, indicating that the temperature is lower than that in other areas of the same latitude, which is due to the influence of the cold current; In the middle and low latitudes, the isotherm of the west coast of the ocean (the east coast of the continent) protrudes to the high latitudes, indicating that the temperature is higher than other areas in the same latitude, which is due to the influence of warm current.
