WebHe refers to this airstream as the ‘‘trowal airstream,’’ since it ascends in the occluded quadrant of the cyclone near a ‘‘trowal’’ (e.g., trough of warm air aloft). Trajectory analyses of model-simulated oceanic cyclones also point to a complex airﬂow pattern. WebThis airstream is referred to as the ‘‘trowal airstream’ ’ and it is shown to be responsible for the production of the ‘‘wrap around’ ’ cloud and precipitation commonly associated with occluded systems. The relationship of the trowal airstream to previously identified cloud and precipitation producing airflows in cyclones is ...
