CameronCat Posted January 27, 2015 Report Share Posted January 27, 2015 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! Quote Link to comment Share on other sites More sharing options...

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.

BeerandWXTogether Posted January 27, 2015 Report Share Posted January 27, 2015 RPM is a WSI (formerly its own private sector company, now a subcompany of The Weather Channel) in-house model. Essentially a higher resolution model. Quote Link to comment Share on other sites More sharing options...

Mitchg Posted January 28, 2015 Report Share Posted January 28, 2015 It's just the wrf-arw rebranded by wsi 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. Quote Link to comment Share on other sites More sharing options...

CameronCat Posted January 28, 2015 Author Report Share Posted January 28, 2015 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." Quote Link to comment Share on other sites More sharing options...
