1. A regional precipitation nowcasting system based on cycle-generative adversarial network (GAN) extension, the system comprising:
an input processor configured to receive an input composite hybrid surface rainfall (HSR) image including precipitation information of a region of interest corresponding to a first time;
a cycle-GAN configured to generate a resultant composite HSR image including precipitation information of the region of interest corresponding to a second time which is later than the first time, based on the input composite HSR image,
wherein the cycle-GAN comprises a first cycle-GAN and a second cycle-GAN which is complementary to the first cycle-GAN, and
wherein the first cycle-GAN and the second cycle-GAN are configured to perform forward image mapping, which temporally goes forward, and backward image mapping, which temporally goes backward, respectively; and
an output processor configured to output the resultant composite HSR image as a nowcasting image of the region of interest.
