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) [72]
- 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
