讲座摘要

Wave-wave nonlinear interactions are a prototype behavior of waves, enabling the transfer of energy across distinct scales. Within the middle and upper atmosphere, a remarkable array of nonlinear interactions involving Planetary-Scale Waves takes place. These nonlinear interactions play a crucial role in establishing vertical connections between different layers of near-Earth space. However, the relevant investigation is limited by the scarcity of relevant observations. These studies typically necessitate synchronized observations spanning multiple longitude sectors. To address these challenges, a series of dual- and multi-station methods were developed. Through the application of these methods, a range of waves were discovered, including the recent discovery of second harmonic generation of Rossby waves reported by Nature Communications. Moreover, the current talk will also discuss the application of the Manley-Rowe relation in quantifying energy transport in nonlinear interactions of atmospheric waves and introduce the adjusted Feynman diagram to represent the nonlinear interactions.
