How do the water systems of China affect its climates compared to the effects of weather systems?

Water systems in China affect local and regional climates in a number of ways. Precipitation is the most obvious manifestation of how water systems shape the climate. Water systems transport water to the land surface through rainfall and snowfall, providing much-needed moisture to vegetation and soils. In turn, this moisture plays a critical role in influencing the development of clouds and storms, essentially modulating weather systems. In addition, changes in water availability through rivers and groundwater aquifers can also affect the physical climate by changing soil moisture, air temperatures, and air pressure, which can influence the development of low-pressure systems and other weather patterns. In China, water systems also play a major role by transferring heat from one region to another through river networks, or from the land surface to coastal areas via the movement of soils and sediments. China’s robust network of rivers and reservoirs is often referred to as the “Great Rivers” and plays a critical role in influencing both temperature and humidity across the country. In summary, water systems in China play an important role in modulating the climate and weather patterns throughout the country.
