Team Scalar and Momentum Advection Assignment #1 10.08.2010 Kirstin Gleicher, Michelle Pitcel, and Andrew Rosenow
Simulation Differences • Used Milbrandt microphysics scheme • Altered momentum and scalar advectionclosure order • Control Run • Momentum was 5th order • Scalar was 3rd order • Experimental Run • Momentum was 4th order • Scalar was 2nd order
Mesocyclone Tracking Algorithm Δx • Looks for the first time with precipitation (reflectivity) • Finds the maximum column-average vorticity • Searches for the next vorticity maximum in two moving domains-one for each post-split supercell • Δx, Δy = 10 km Left Mover Domain Δy Previous meso location Right Mover Domain Δy Δx
