The “conveyor belt model” was developed and refined (most recently by authors such as Browning<\/strong><\/a>, Carlson<\/strong><\/a>, and Young<\/strong><\/a>) to help visualize the airflow through mid-latitude cyclones (schematic 1<\/strong><\/a> | schematic 2<\/strong><\/a>); the flow is ascending in all 3 conveyor belts (producing the enhanced moisture and cloud signatures seen on the water vapor imagery),<\/em> but the air rises to higher altitudes in the two warm conveyors than in the cold conveyor.<\/p>\n

AWIPS images of the GOES-11 water vapor channel at 3-hour intervals (below)<\/strong><\/em> show that during the following 2-3 days this cyclone rapidly occluded, became quasi-stationary, and then eventually transitioned to a “cut-off low” which began to slowly retrograde to the northwest on 15-16 January.<\/p>\n
