Internal solitary waves commonly observed in the coastal ocean are oftenmodeled by a nonlinear evolution equation of the Korteweg–de Vries type. Because these waves often propagate for long distances over several inertial periods, the effect of Earth’s background rotation is potentially significant. The relevant extension of the Kortweg–de Vries is then the Ostrovsky equation, which for interna...

Abstract NASA’s Perseverance rover’s Mars Environmental Dynamics Analyzer is collecting data at Jezero crater, characterizing the physical processes in lowest layer of Martian atmosphere. Here we present measurements from instrument’s first 250 sols operation, revealing a spatially and temporally variable meteorology Jezero. We find that temperature four heights capture response atmospheric sur...

We present single-column gravity wave parameterizations (GWPs) that use machine learning to emulate non-orographic (GW) drag and demonstrate their ability generalize out-of-sample. A set of artificial neural networks (ANNs) are trained the momentum forcing from a conventional GWP in an idealized climate model, given only one view annual cycle phase Quasi-Biennial Oscillation (QBO). investigate ...
