GFS mfscu General Algorithm

• Specify downdraft fraction
• If the condition for cloud-top instability is met, increase downdraft fraction
• First-guess level of downdraft extension (mrad)
• Compute entrainment rate
• Compute buoyancy for downdraft air parcel
• Compute downdraft velocity square(wd2)
• Update entrainment rate
• Compute entrainment rate averaged over the whole downdraft layers
• Compute downdraft mass flux
• Compute downdraft fraction as a function of mean entrainment rate (Grell and Freitas(2014) [70]
• Compute scale-aware function based on Arakawa and Wu (2013) [9]
• Compute final scale-aware downdraft mass flux
• Compute downdraft property using updated entranment rate
