Trowal airstream
WebThe TROWAL airstream is characterized by strong ascent over the cold conveyor belt, and cyclonic turning towards the surface cyclone. Despite the Limiting Streamline (LS), air moves from the warm sector to near the Low, contrary to Carlson's conceptual model. WebIt is a coherent flow of air that originates in the warm sector boundary layer and ascends cyclonically through the trowal. The airstream is color coded with the colors indicating the …

Webmodel using D3D is the trowal (trough of warm air aloft) airstream (Martin 1999), which is evaluated using the airflow along a surface of equivalent potential temperature wrapped around an extratropical cyclone (see Figure 1).
