Namely winter. The reason I ask, is, given some of the "Super Typhoons" in the Pacfic(forgot the name), we had an early snow here in November 2014 due to the jet stream being totally screwed up

I do know that when Atlantic hurricanes head to the North Atlantic it transports a lot of tropical airmass and in turn creates High Latitude blocking also known as a negative NAO. When there is a negative NAO (Blocking) the Jet stream can dig down and stay longer in Eastern U.S. Doesn't mean entire east, doesn't mean it's an arctic blast. All depends on other forces and players.


As far as the pacific, yeah, a recurving Typhoon makes the Jet stream wavy and in turn brings active weather pattern into North America. but as I always say, there's so many other players on the map.


Speaking of 2014..good reading here.


How Typhoon Nuri is changing the weather forecast in North America


Quote:
"Archambault says that recurving typhoons like Nuri “increase the chance of having extreme weather across North America” about three to five days later, because the air flowing out of the typhoon gets funneled into the North Pacific jet stream. This adds energy to the jet, which “perturbs” it, she says."


"Typhoons and hurricanes are like giant atmospheric exhaust fans, with a huge amount of air being evacuated from the storm and into the surrounding environment."


"For her thesis, she looked at 300 cases of recurving tropical cyclones (these include typhoons) from 1979 to 2009, and started to see typical downstream patterns. She concluded that the events, on average, did affect the airflow across North America, and that this was especially the case when there is a trough of low pressure to the northeast of a typhoon, as there is with Nuri."


"Cordeira said in an interview that recurving typhoons can lead to highly varied weather patterns in the U.S. as the jet stream waves move through, with unusual warmth followed by sudden cold. That’s what is expected this week across the eastern half of the country, with a warmup followed by another taste of winter. Nuri's jet stream interactions, combined with other factors, may mean that the eastern U.S. will see multiple rounds of cold weather during the next several weeks at least, with warmer and drier conditions in the West."

The 6-10 day rule seems good for about when it's near Japan Latitude give or take

BTW.. Typhoon Nuri happened end of October 2014... This was the pattern early November 2014.. Coincidence? Most likely not but again... other factors played a role. If the Vortex wasn't displaced we wouldn't of had Historic snows in South Carolina, NC, TN, KY, VA, GA. Huge Lake Effect snows.





Experts traced the jet stream wanderings to Typhoon Nuri. The typhoon pushed the jet stream off course and north with a large body of warm air as it moved into the northern Pacific. As the air current bulged northward, arctic air downstream had nowhere to go but south, pushing the jet stream ahead of it over the continental US. Energy from Typhoon Nuri then proceeded to be carried down the jet stream to Buffalo, resulting in the warming spell that causes flooding
