L.15 Midlatitude Cyclones Flashcards
A cyclone refers to an area of intense low pressure around which the winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. You can also think of midlatitude cyclones as systems that mix warm and cold air masses together.

Virtual Product Optimization of Cyclone Pre-separators for …
Typically, such dust pre-separators are designed as blocks of several cyclone cells with axial flow that are connected in parallel. The dusty air is set in rotation in the cyclone cells by a static swirl generator. Due to the centrifugal forces at work, particles of higher density are carried outward and separated from the main flow.
