- Battle zone in the sky: squall line structure
- W003783S
- Battle zone in the sky. This squall line is rolling slowly forward, lifting warm air smoothly as it advances. Air converges on the axis and turns right along and into the long shelf cloud, which is the gust front boundary separating warm inflow from cooler outflow. Towers build and mature to the right, adding their rain to the backside wall of precipitation.
