[RegCNET] RegCM3 and MCS

[Gregory Jenkins]

Hello Vincent.  The MCSs are very difficult to simulate, especially squall
lines.  In general you need to be at 20 km or less, using non-hydrostatic
conditions and cloud microphysics.The best simulations that I have seen in
the literature are at this scale or at finer scales of 5-12 km.  The NCEP
reanalysis and ERA40 can provide the overall forcing (such as wind shear or
AEW forcing).
