Dual-Doppler radar system is a unique instrument to detect the three-dimensional structure of cloud systems including the rain particle distribution and their movement. In the real observation of cloud systems using dual-Doppler radars, researchers have to choose a variety of options, such as time of collecting three-dimensional volumes or intervals of antenna scans, depend on their altitude, their speed of propagation, and their development activity. All the options are not satisfied, the tradeoff for high spatial resolution is lower time resolutions. Researchers have to determine the options before observation, however, it is difficult to know the effect of the tradeoff for the options they made. To know the better options before the observation, an idealized dual-Doppler observation is made using the numerically simulated cloud systems developed in the same location for observation targets. This documents introduces the process of finding better options on the observation of tropical cloud systems in the western Pacific Ocean.
