Structural behaviour of inversions in the lowest 810 feet during their development and decay in winter at Winnipeg
This study investigates the structural behaviour of winter inversions lasting not less than 10 hours in the lowest 810 feet at Winnipeg. Attention focuses on the development and decay processes in relation to synoptic meteorological conditions. The temporal range of inversion development and decay i...
