The processes responsible for generating the mean azimuthal atmospheric winds observed on Jupiter and Saturn, which feature large prograde equatorial jets and jets of alternating direction at higher latitudes, have yet to be conclusively resolved. Results from three dimensional numerical models...

We report upon an experimental study of internal gravity waves generated by the large-amplitude vertical oscillations of a circular cylinder in uniformly stratified fluid. Quantitative measurements are performed using a modified synthetic schlieren technique for strongly stratified solutions of...

Internal gravity waves transport energy and momentum in both the atmosphere and the ocean. This physical process occurs at such small length scales that it is not captured by coarse resolution numerical models of weather and climate. A series of experiments is presented that model the generation...

In modern cosmology, many efforts have been put to detect primordial B-mode of cosmic microwave background polarization from the gravitational waves generated during inflation. Considering the foreground dust contamination of microwave polarization maps, it is essential to obtain a precise...

It has been well known that turbulent motions are ubiquitous in the interstellar medium. These motions are very important in governing various astrophysical processes like star formation. Both observational and numerical studies are important to understand turbulent motions, and a gap between...
