Climate services are becoming more and more vital to human being's adaptation to climate variability and climate change. As one of the most affected countries in the world, China has attached great importance to meteorological disaster prevention and mitigation. To play a leading role, the Chinese meteorological departments are making steady efforts to strengthen the capabilities on climate system monitor, research, prediction, information sharing and service delivery. In following with the WMO’s on-going initiative GFCS, CMA is improving the China Framework for Climate Services (CFCS) which puts priorities on risk management on agriculture and water resource, user interface, assessment of meteorological disaster and vulnerability, and climate operational capacity of service-driven.
