RISA Theoretical Study on the Spontaneous Radiation of Inertia–Gravity Waves Using the Renormalization Group Method. Part I: Derivation of the Renormalization Group Equations
Publisher: American Meteorological Society
Abstract: y using the renormalization group (RG) method, the interaction between balanced flows and Doppler-shifted inertia?gravity waves (GWs) is formulated for the hydrostatic Boussinesq equations on the f plane. The derived ...
A Theoretical Study on the Spontaneous Radiation of Inertia–Gravity Waves Using the Renormalization Group Method. Part II: Verification of the Theoretical Equations by Numerical Simulation
Publisher: American Meteorological Society
Abstract: he renormalization group equations (RGEs) describing spontaneous inertia?gravity wave (GW) radiation from part of a balanced flow through a quasi resonance that were derived in a companion paper by Yasuda et al. are validated ...
Parameter Sweep Experiments on Spontaneous Gravity Wave Radiation from Unsteady Rotational Flow in an f-Plane Shallow Water System
Publisher: American Meteorological Society
Abstract: Inertial gravity wave radiation from an unsteady rotational flow (spontaneous radiation) is investigated numerically in an f-plane shallow water system for a wide range of Rossby numbers, 1 ≤ Ro ≤ 1000, and Froude numbers, ...
A Dynamical Mechanism for Secondary Eyewall Formation in Tropical Cyclones
Publisher: American Meteorological Society
Abstract: AbstractThis study proposes that secondary eyewall formation (SEF) of tropical cyclones (TCs) can be attributed to an instability of flow in the free atmosphere coupled with Ekman pumping. Unstable solutions of a 1.5-layer ...
