Hector simulation
We found simulation largely depending on:
• Model initialization scheme
• Lateral boundary conditions
• Physical processes represented in the model
Hector simulation – 06.02.2006 case
WRF initial conditions
1km resolution WRF domain
WRF lateral boundary conditions
Hector simulation – 06.02.2006 case
Observed and simulated radar reflectivity along the W-E cross section of Hector
Observed Simulated

SummarySummary
• Two modes of simulationTwo modes of simulation– OF – doesn’t work too well in generalityOF – doesn’t work too well in generality– DA – gives good agreement for a lot of DA – gives good agreement for a lot of
cases, but the statistics show too low cases, but the statistics show too low cloud fraction.cloud fraction.
• Aerosol effects are present for the 6Aerosol effects are present for the 6thth February case.February case.– Need more simulations of different cases Need more simulations of different cases
