Katabatic wind propagation over the western Ross Sea observed using ERS-1 scatterometer data
Wind fields derived from ERS-1 scatterometer data, acquired over the open water present in the western Ross Sea during the summer season, are used to study the patterns of mesoscale atmospheric flow connected with surges of katabatic air from the Terra Nova Bay convergence zone, located in the coast...
