چکیده

Abstract Gravity waves (GWs) and their associated multi‐scale dynamics are known to play fundamental roles in energy momentum transport deposition processes throughout the atmosphere. We describe an initial machine learning model—the Compressible Atmosphere Model Network (CAM‐Net). CAM‐Net is trained on high‐resolution simulations by state‐of‐the‐art model Complex Geometry (CGCAM). Two applications a Kelvin‐Helmholtz instability source mountain wave generation, propagation, breaking, Secondary GW (SGW) generation two wind environments described here. Results show that can capture key 2‐D modeled CGCAM with high precision. Spectral characteristics of primary SGWs estimated agree well those from CGCAM. Our results achieve several order‐of‐magnitude acceleration relative without sacrificing accuracy suggests potential for enable efficient accurate descriptions secondary GWs global atmospheric models.

Gravity Wave Generation and Breaking Observedwith Radiosondes at Ushuaia (argentina)

High resolution radiosondes that were launched at Ushuaia (54.8S) during October-December, 1995 are examined. Episodes of high gravity wave activity are found in the lower stratosphere (from 10 km to 24 km). The enhancement of gravity wave activity is ascribed to the conjuction of two factors: gravity wave generation and Doppler-shifting. Two radiosondes with high wave activity cases are examin...

Gravity Wave Watching

It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, whe...

Gravity Wave Lensing

Here we show that a nonlinear resonance between oceanic surface waves caused by small seabed features (the so called Bragg resonance) can be utilized to create equivalent of lenses and curved mirrors for surface gravity waves. Such gravity wave lenses, which are merely small changes to the seafloor topography and therefore are surface non-invasive, can focus/defocus energy of incident waves tow...

Gravity wave turbulence in wave tanks: space and time statistics.

We present the first simultaneous space-time measurements for gravity wave turbulence in a large laboratory flume. We found that the slopes of k and omega wave spectra depend on wave intensity. This cannot be explained by any existing theory considering wave turbulence as the result of either breaking events or weakly nonlinear wave interactions. Instead, we show that random waves and breaking ...

A Macroscopic Gravity Wave Effect

Gravitational waves, although generally associated with extremely microscopic effects, can displace by hundreds of kilometers the pulsar interstellar scintillation patterns that bathe the Earth. The combination of the pulsar and the interstellar medium acts as a kiloparsec-long, nature-provided gravity wave amplifier. We show how an effective scheme for the detection of periodic gravity waves c...
