So kinda new to some of these rules. I do remember that recurving typhoon means trough in the eastern US. So I checked out what was going on in the West Pacific. It doesn't usually look like this does it? What are the possible ramifications downstream? Similar pattern goes on in Gulf of Alaska.


Hey stretchct! Per the paper, the correlation is 6-10 days after what happens in East Asia we will see downstream effects in the ECONUS. That being said, you can see in the paper that the EAR (East Asia Rule/Typhoon Rule), scored lower than the BSR. Just like the BSR, I stopped looking at medium range modeled solutions in those regions due to being burned on multiple occasions. The most I go out is 96hr so keep that in mind.

"For the EAR, the highest correlations were obtained for the 500 hPa heights at Seoul, South Korea (37.5N 127E), and those at Nashville, TN (BNA)"

So IF I'm reading the paper correctly, the best correlation for the EAR is Seoul to Nashville, so if I'm 850 miles (roughly) northeast of Nashville, I should be correlated with 850 miles northeast of Seoul.

Making that upper low right around my area 60hrs+6-10 days - so 8.5 to 12.5 days out. And the overall vortex pattern should last for a while to the north of Nashville.

Does it work with the actual heights or temps, or just the anomalies? Should be fun.

Yes, the point correlation is equidistant and can be used 1:1 if desired. I created a "true size" overlay for the EAR a while back and host forecast maps based on it. You can find them here. Click on "Maps" in the EAR section. I translate the EAR connection with H5 flow, anomaly and/or a rate of change. Enjoy!

I remember on the old website it was easy to access archives & look back at previous EAR maps. Do you still have an easy access archive now?

Yes. http://consonantchaos.com/archive.html

It is not user friendly, just a list of files, but there is a decoder ring.

Example;

EAR Filename: "170903140055.jpg"

"170903xxxxxx" = YYMMDD
"xxxxxx140055" = East Asia Rule

So look for all files with suffix "140055" regarding EAR.

EDIT: And to move quickly between days, just change the date in the url filename.

The paper used anomalies of 500mb heights. Even though some people preach that "you don't live at 500mb", it can be used successfully if applied correctly.

In a literal sense, you are better off knowing that using a 1:1 correlation will only get you in trouble. This premise is not scientifically based and has proven that it's foolish to follow a 1:1 as the earth doesn't work that way. Can it be close? Of course! Again, go into organic forecasting of BSR & EAR in that they are pattern recognition tools and not the "holy grail".

Unlike last winter, There will be some of the coldest air in the world ready to strike when MJO goes into the holy grail of cold phases in Feb 8,1,2,3
forecasted on ECMWF to where it was around Dec 17 GLAAM also heading higher Winter in west for now, but east target after thaw


...JB sure can go out on a limb to further his 'rose-colored glasses' (blues if it came to a temperature map)

...idee doesn't understand why 'forecasters' use an 'index' to promote their agenda...reality is not an 'index'...an 'index' is a partial description of a recognizable 'pattern'...yet it is not the 'reality'...

...oh yeah...no reasonable thinking allowed...MJO is not the only 'player' in town folks... dry.gif
