We find that the highly localized asymmetric and complex configuration of energy transfer flux between large- and small-scale components is caused by the nonlinear interaction between a large-scale vortex with an initial axi-symmetric flow and four beta meso-scale vortices. The complex structure is characterized by a fine pattern, which contains seven closed systems with spatial scales of less than 100 km, embedded in a positive flux wave train and a negative wave train, respectively. The average wind speed decreased with time in the positive flux region, but was nearly unchanged in the negative flux region. This pattern reveals the evolutionary asymmetry and localization of wind speed of the major vortex. The track of the major vortex center has a trend toward the center of the negative flux center, indicating that there is a certain relation between the complex structure of the energy transfer flux and the motion of the major vortex center. These results imply that the formation and evolution of the fine and complex structure should be attributed to the nonlinear interaction between the vortices at different spatial scales.
