Theoretical Studies on Baroclinic Waves and Frontogenesis inthe Presence of Small Moist Symmetric Stability

本项目的目的是研究非线性斜压波的发展和三维锋生在基本射流和条件湿润带共存的情况下。采用半拉格朗日坐标变换和有限元法求解三维湿式半地转方程。这些结果有望揭示层状降水和锋面雨带的形成及其对锋面区演变的影响。

The objective of this project is to investigate the development of nonlinear baroclinic waves and three-dimensional frontogenesis in situations where a basic jet and a conditionally moistured zone coexist. The semi-Lagrangian coordinate transformation and the finite element method will be used to solve the three-dimensional moist semi-geostrophic equations. The results are expected to shed light on the formation of stratiform precipitation and frontal rainbands, and their effects on the evolution of the frontal zone.
