%X Partitioning and reconstruction problem of the wind in a limited region is a useful diagnostic technology. From the non-divergent and non-rotational wind component, one can know more about the structures of meso-scale systems. The effective way to wind partitioning and reconstruction in a limited region is to calculate the stream function and velocity potential in the same limited region. When the reconstructed wind approachs the original one, it means the partitioning process is successful and the calculated stream function and velocity potential is accurate. The most commonly used partitioning methods in the past are summarized in this paper, and the harmonic-sine/cosine method is emphasized. Case study shows that the harmonic-sine/cosine method can partition and reconstruct the wind in a limited region, and its results are encouraging for studying the dynamical structures of meso-scale systems.
