New model or just new to me?

Recommended Posts

Hi

 

Figured I'd ask this here to stay out of the way of the other active topics.

 

I often watch a non-Phila market TV station via cable. Their weather presenters have recently begun including an occasional graphic  that shows how various computer models disagree. For instance, if discussing upcoming rainfall (QPF) the graphic might show:

 

Euro - 0.22   NAM - 0.40  GFS - 0.03  RPM - 0.30

 

The RPM model designation is new to me. Something new? Proprietary?   My Googling didn't turn up much.

 

Just wondering who the newcomer is and how trustworthy it might be. Any info appreciated.

 

Thanks!

RPM is a meso model like the nam. Best used under 24hrs. I don't look at it much really, so I'm not sure how well it has been doing. I think a lot of the news stations use a version of it as "an in house" model.

It's just the wrf-arw rebranded by wsi

 

Speaking of models, you are not going to have the current nam to kick around next winter.

Really, lol. Yeah it's not hard assuming you have the computing power to get the same model and setup the physics the same way as the the wrf arw but change only one of many parameters. Many NWS offices have there own WRF's as well. Most met university programs do as well.

Thanks all for the info and replies. I was suspecting that the TV station had adopted RPM as an in-house touchstone.

 

It's even more interesting that they'd adopt a product owned by TWC when they (the TV stn) make a big deal out of their

association with AccuWeather who almost certainly have their own modelling programs.  Go figure. (or bring $$...)

 

It'll be interesting to see how RPM plays against "the big kids."

AccuWeather didn't when I was there. But, that was 8 years ago now.
