Describe the major aspects of the conveyor belt model
What will be an ideal response?
Answer: In the conveyor belt model, the warm conveyor belt between the cold and warm fronts is responsible for much of the large band of cloud cover evident in the satellite image. The cold conveyor belt flows toward the center of the low-pressure system at the surface and rises as it does so, producing the cluster of clouds over the Dakotas and Minnesota. The dry conveyor belt flows in the upper troposphere, with some of the flow sinking as it approaches the cold front. The rest of the conveyor belt remains in the upper atmosphere and remains dry and relatively cloud free. That is evident in (b) as the gap over Wisconsin separating the major cloud regions.
