This paper described the design and development of the weather modification operational platform based on MICAPS V 3.2 core framework. First of all, we recommend the major function, features of modular design and system interface of MICAPS V 3.2. Then presented the workflows, contents and major products of weather modification, furthermore, pointed out the interactive method of different types of data in this system. Finally, design menu and interface layout were given to accomplish the development of the system aiming at the characteristics of weather modification, and displayed the examples of weather modification work main products which have been completed. The successful development of this weather modification operational platform broadens the application field of MICAPS V 3.2 and it is worth promoting nationwide.
