Stratospheric and tropospheric wave measurements near the Andes mountains

Mostrar otras versiones (1)

Experimental results and interpretation of temperature, pressure and wind velocity measurements, performed with an instrumented balloon, are presented. The balloon, an open-type stratospheric one was launched from Mendoza (Argentina), near the Andes mountains. The data analysis suggests the presence...

520 3 |a Experimental results and interpretation of temperature, pressure and wind velocity measurements, performed with an instrumented balloon, are presented. The balloon, an open-type stratospheric one was launched from Mendoza (Argentina), near the Andes mountains. The data analysis suggests the presence of a large amplitude quasi-inertial gravity wave, with intrinsic period close to 0.5 days, and vertical wavelength of around 1.7 km just below the tropopause. The possible orographic origin of this wave is discussed. A Fourier analysis confirms the existence of this mode, simultaneously in the temperature and in the wind velocity components. A hodograph of the zonal and meridional wind components shows the expected counterclockwise sense of rotation of the horizontal velocity with increasing altitude, corresponding to a long period gravity wave, in the southern hemisphere. It is found that the vertical wind velocity variations measured by the anemometer, are mainly due to buoyancy force variations induced by the wave on the open stratospheric balloon. The vertical profile obtained by the anemometer is anticorrelated with the rate of ascent or descent of the gondola. As a consequence, the wave induced velocity is very difficult to obtain using these balloons, contrary to the case of radiosonde balloon data. The differences in the response of open stratospheric and radiosonde-type balloons to the presence of internal gravity waves may be explained by their different design and material characteristics.
