Abstract On 20 October 2016, aircraft observations documented a significant train of lee waves above and downstream the Snæfellsnes Peninsula on west coast Iceland. Simulations this event with Weather Research Forecasting (WRF) Model provide an excellent representation observed structure these mountain waves. The orographic features producing are characterized by isolated Snæfellsjökull volcano...

Recent VLBI monitoring has found transverse motions of the M87 jet. However, due to limited cadence previous observations, details motion have not been fully revealed yet. We regularly monitored jet at KVN and VERA Array (KaVA) 22 GHz from December 2013 June 2016. The average time interval observation is ∼0.1 year, which suitable for tracking short-term structural changes. From these well repre...

Laboratory measurements of the fine space-time structure of short gravity-capillary waves, as well as Ku-band scattering at grazing and moderate incidence from spilling and plunging breaking waves in a wave channel are presented. Unsteady breaking waves are generated by focusing the waves in space and time. A scanning laser slope gauge was used for measuring short waves of wavelength 0.2-20cm, ...

Electromagnetic waves in vacuum and most materials have transverse polarization. Longitudinal electromagnetic with electric field parallel to wave vector are very rare appear under special conditions a limited class of media, for example plasma. In this work, we study the dispersion properties an easy-to-manufacture metamaterial consisting two three-dimensional cubic lattices connected metallic...

We derive a normal form of nonlinear equations for short equatorial waves considered in the framework of the rotating shallow water model. We show dynamical splitting of equatorial Rossby and inertia-gravity waves. We derive an effective Hamiltonian for the short inertia-gravity waves and consider their kinetics using the weak turbulence approach. Stationary power-law energy spectra are obtaine...
