Does the temperature rise slowly in spring in places with strong marine characteristics? For example, Japan, please help.

Yes, in places with strong oceans, the temperature rises slowly in spring.

Because the land heats up and cools down quickly (the specific heat is small), the ocean heats up and cools down slowly (the specific heat of water is the largest).

Japan belongs to an island country and is greatly influenced by water vapor from the ocean. The monsoon climate is maritime. The temperature rises and falls slowly, and the daily temperature difference is smaller in the annual temperature difference.

China and Xinjiang belong to continental climate (temperate continental climate).

Living deep inland, the land heats up and cools down quickly, so the daily range of continental climate is greater than that of annual range. For example, in Turpan Basin, people wear cotton-padded jackets in the morning, gauze in the afternoon and eat watermelons around the stove.
