I will certainly know when the changeover happens because l watch the model closely as you know.

I do agree re ACC r weakness on coastal diagnosis on rain bands coming over the ranges.

I also have learnt that ACCESS is not configured for storm potential and just seems more attuned to lifted index convection.

I also am aware that ACC cannot accurately resolve mslp out at sea during big depressions and cyclones.

ACC g also shows higher rainfall potential than ACC r. So all in all it will be interesting to see how the new upgrade goes.

I think l remember MEGA saying he didn't like the GFS upgrade.So sill look on with interest

Nah all models are designed to simulate thunderstorm activity including ACCESS-R. Just that they do it in similar buy slightly different ways. ACCESS-R doesn’t use LI just to simulate convection. It, like most other models, uses physics and thermodynamics for that.
Also, the precip on the ACCESS charts on the Bureau’s website are heavily interpolated/smoothed so you sometimes won’t see the finer details.



Ok. Thanks for that.

Would l be right in saying models generally do better with stronger systems.Rather than marginal systems.?
