Squall Line with Mesoscale Convective Vortex
Entry ID:

[ Get Data ]

Abstract: The evolution of a squall line with a mesoscale convective vortex is modeled
here using the Klemp-Wilhelmson numerical algorithm. The circulation patterns
around the storm along with the interaction of rain, cloud water, and potential
temperature are simulated.The images and animations shown here represent
visualizations of a squall line with a mesoscale convective vortex (MCV) using
data generated by the Klemp-Wilhelmson numerical model. The model is
initialized with 5 storm cells along a 160 kilometer long line. The squall line
is evolving in an environment of moderate vertical windshear with winds
increasing by 20 m/s between the ground and 2.5 KM above ground.
