Analytic solutions obtained previously by the authors for the vertical response of an open stratospheric balloon to the presence of inertio-gravity waves in the limiting cases of null and perfect skin thermal conductivity, are here extended tothe more realistic case of finite conductivity. A monochromatic wave with simultaneous variations in density, velocity and temperature is considered. From the perfect conductivity limit, in which the velocity variations of the wave dominate the balloon's behavior, it is observed that the air density oscillations become significant with decreasing skin thermal conductivity, reaching monotonically their maximum influence in the adiabatic limit. http://www.exa.unicen.edu.ar/fluidos/dfyp/Fluidos2001/Default.htm
