Inertia gravity waves in the upper troposphere during the MaCWAVE winter campaign ? Part II: Radar investigations and modelling studies
International audience We present an experimental and modelling study of a strong gravity wave event in the upper troposphere/lower stratosphere near the Scandinavian mountain ridge. Continuous VHF radar measurements during the MaCWAVE rocket and ground-based measurement campaign were performed at t...
