Confuzzled Posted December 19, 2010 Share Posted December 19, 2010 This came up in tonights 00z potential Christmas day snow event. I looked at the KMA a few times last year and I was wondering if anyone knows of any sources (papers, links, etc) with information on the KMA and its reliability? Alternatively, if someone looks at it consistently I would be interested in hearing your informal opinion as compared to other models. Link if you've never heard of it: http://web.kma.go.kr/eng/weather/images/forecastchart.jsp Global model --> NH Surface view. USA will be on the top of the map and upside down (find it using Florida or Longitude like I did) Link to comment Share on other sites More sharing options...
winter_warlock Posted December 19, 2010 Share Posted December 19, 2010 KMA at 156 has nice low off delmarva... Link to comment Share on other sites More sharing options...
Confuzzled Posted December 19, 2010 Author Share Posted December 19, 2010 KMA at 156 has nice low off delmarva... I just looked at that. On board with the GFS. I love snow so that makes it reliable. Link to comment Share on other sites More sharing options...

SteveB Posted December 19, 2010 Share Posted December 19, 2010 Matches up fairly well with the Euro ens mean for the same time fwiw. Link to comment Share on other sites More sharing options...
winter_warlock Posted December 19, 2010 Share Posted December 19, 2010 Matches up fairly well with the Euro ens mean for the same time fwiw. kinda weird how most of the models and ensembles are in a fairly good agreement 6 days out... dont happen that often Link to comment Share on other sites More sharing options...

I looked at the KMA a few times last year and I was wondering if anyone knows of any sources (papers, links, etc) with information on the KMA and its reliability? The model output from the Korean Met Agency is actually a version of the Unified Model (which is the proper name of the UKMET model) that they started running in 2007. They started using a 4DVAR assimilation scheme (like the ECMWF) earlier this year, and they're planning a resolution increase from the current 40 km to 25 km. The red line on the graph is their 4DVAR-based upgrade...it'll be interesting to see more results from that, especially after the resolution upgrade.

Confuzzled Posted December 19, 2010 Author Share Posted December 19, 2010 looks like for now it's solidly inferior Yep but it has improved significantly with the update and once the resolution increases it may be worth looking at! Link to comment Share on other sites More sharing options...

baroclinic_instability Posted December 19, 2010 Share Posted December 19, 2010 I think we have plenty of guidance as is with the ECM/GFS/CMC/UKMET and all the ensembles to go with them. Beyond that, some good forecasting will go a lot farther than adding in another numerical model to the suite. Link to comment Share on other sites More sharing options...

Yes_Probably_Maybe_No Posted December 20, 2010 Share Posted December 20, 2010 looks like for now it's solidly inferior it's worse than the JMA Hard to disgree with Baroclonic Instability.We have enough model guidance; what we need is good forecasting. At the same time, it wouldn't hurt to have another "accurate" model out there to increase sample size/confidence. We'll see how the upgrade goes... BTW, shouldn't we call it the GDAPS since KMA is actually the name of the organization and not the model itself? Link to comment Share on other sites More sharing options...

Looks like the new one is the "Um" model? :;; That's pretty good..XD Sorry just seemed funny at the time.. Link to comment Share on other sites More sharing options...
Cory Posted December 21, 2010 Share Posted December 21, 2010 BTW, shouldn't we call it the GDAPS since KMA is actually the name of the organization and not the model itself? We do the same thing with the ECMWF and UKMET: ECMWF model = Integrated Forecast System (IFS) UKMET= Unified Model (UM) GDAPS is their old version; KMA would also now be called the Unified Model.
