文章概述了大气科学的涵义及其对人类生存和发展的重要性，包括防灾减灾、气候资源的开发利用、生态环境的保护、水资源的可持续利用等。大气科学造福人类的途径是通过大气信息的开发利用，而必须按信息工程的特点进行工程化。简要回顾气象主要工程建设的基本情况及其应用效益，提出未来30年内的发展和大气科学工程建设的基本思路、需要建设的若干骨干工程：大气监测自动化系统工程、短期气候预测业务系统工程、卫星综合应用业务系统延伸工程、中尺度（局地）数值天气预报业务系统工程、人工影响天气系统工程、气象服务体系工程等，以及进行建设的若干主要措施。

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.
