Large amplitude waves detected with balloons near the Andes mountains
Spectral results from a vertical sounding of temperature and wind velocity performed with an open stratospheric balloon in Argentina near the Andes mountains between 12 and 25 km of altitude, are reported. The use of sonic anemometers allows for a higher resolution than in previous experiments. The...
