Squall Line Basics?

[J Trueblood]

Hi everyone,
I am trying to use vensim to mathematically model the life cycle of a squall line. i am having trouble finding an in depth discussion on the components and evolution of squall lines. I know the updraft occurs in the front of the system, and the storm sustains itself on the outflow boundary. My question is how the downdrafts affect the system. How does a downdraft in front of the storm affect it, and vise versa? Does anyone have any info they can share on squall line genesis with me? Thanks
