A brief account of the meaning of atmospheric science and its importance to human*s existence and development are given, including taking precautions against natural calamities and reducing natural disasters, development and use of climate resource, protection of ecological environment, sustainable utilization of water resource, etc. Atmospheric science brings benefit to mankind through the development and use of atmospheric information, which is necessary to be engineered inaccordance with the characteristic of information engineering. The basic conditions and effects of main meteorological engineering constructions are briefly reviewed. Basic thinking for the next three decades about atmospheric science engineering construction and some key projects to be constructed and some main measures are initially envisaged .Key projects include automatic atmospheric monitoring system enginnering, short-range climate forecast system engineering, satellite synthetic application system extending engineering, mesoscale (local) numerical weather forecast system engineering, weather modification system engineering and meteorological service system engineering.
