What role does water play in regulating climate?

This has a physical component. When the temperature is high in summer, the movement of water molecules intensifies, vaporization accelerates and heat is absorbed. Because of the large specific heat capacity of water, it is necessary to absorb or release more heat when the temperature rises or falls by one degree Celsius, so that the temperature can be controlled not to be too extreme. The temperature difference between day and night is small in coastal areas and large in inland areas because the specific heat capacity of sand and gravel is smaller than that of water. It can be seen that water plays an important role in regulating temperature. Climate is determined by latitude, land and sea position and topography. Coastal areas are generally maritime and related to water bodies. The Mediterranean climate is abnormal, with more precipitation in winter. In addition, there are warm currents and cold currents caused by the ocean. It has a great influence on the climate.
