I predict we may need to have a new thread soon: The Japanese Snow Season 16/17
I'll start that when it looks like they will open some places in Hokkaido
Furano have penciled in Saturday as opening day.... may end up being a washout
Because it's the Weather Forum and not the resorts propaganda forum ( ), we'll start when (or just before) the actual winter snowfall season begins, and not the resorts' launch!!!
Okay, thanks for the info. You produce some interesting information.
Yeah, that's a little ridiculous for November.
But in mid winter, not so ridiculous
Even in mid winter, 150cm in 24 hours at Nozawa would be extremely unusual.
I've seen 180cm in 3 days, or 60cm in 12 hours
****sarcasm was intended
That's when you use this:
We got it Actually in light of the Aus snow reports I thought it was very funny. With the actual snowfalls you get in Japan they would be reporting way more than that with the way they measure snowfall.
Stay on Topic .....
Come on Sandy ....Claude Cat is better than you in the Moderation dept
I taught CC that!!!
It's the pre-season thread, so I can be a bit more lenient!!
Only 8.0 degrees in Tokyo and dropping.
Now, you may be tempted to think that winter is arriving, but it doesn't have the feeling of winter at all. It's raining, and meanwhile, it's just a little colder in Hakuba(6.7), at 703m. And it's 3.7 degrees at Kutchan (near Niseko)
Yes, winter is still some time away.....
I just looked at the Niseko webcams and its dire! the season is ruined ! gotta cancel my flights.
Season is a fizzer
It's only August September October November
Only 11.7 degrees in Tokyo today, but 20 degrees forecast tomorrow.
Nice and cold for a dump in Hokkaido and North Honshu. I expect the winds will dump snow in Central Honshu too!
The problem with these low pressure system driven snowfalls is what comes before:
So any snow that's fallen before then will be washed away in central Japan, and at Niseko (for example) below 800m.
Freezing down to sea level in the next one for central Japan, but huge wind blown is not the best for a base in Hokkaido.
And then the NEXT 6 hour increment in the model shows something COMPLETELY different!!!!
Furano partially open the top yesterday
Did somebody order a massive high over Siberia / Mongolia?
Yeah still alot of movement this far out. Looks eerily like that double headed beast that swung through quite early last season - snow to funny parts of Honshu.
Putting against the anomaly...
Now we just need the lows to go away...
Is this good or bad for honshu..
Complicated chart talk Not really.
About Honshu, it depends...
When the big thing gets high or the little thing gets low, sometimes it will rain, sometimes it will snow, and sometimes it won't.
I see you're getting in some practice!!
I don't see the funny side
Never hurts to practice.....
To be good for Honshu you want a big fat stable mudda of a high sitting put over Siberia directing cold nor-westerleys over Japan..
Asking the weatherman/woman about the weather the answer: "it depends...".
Okay here's some specifics...
Currently favouring North Honshu and Hokkaido with a NE wind with the low to the North of Hokkaido...
@Brad Filmer Look at the big 1067hPa high over Central Russia.
Low shifts to the east of Japan, creates Cold Northernly winds across Japan. I would expect some snow...
Next Event 27-29 Nov
Low passes over Japan, snow north of the low... Probably rain for Central Honshu resorts...
Low makes way for strong northernly- ne winds for Honshu. Could be a nice snow event... Hokkaido still has the Western flank of the Low.
Possible snow forecast in Tokyo on Thursday, by JMA!!!!
If that actually happens, it will be the earliest snow I've seen in Tokyo, by probably a MONTH!!!!
Snow forecast in Nagano City.
Meanwhile, it was just under 22 degrees yesterday at my place in Yokohama!!!!!
Winter not here yet!!
Yeah, and if it snows in Tokyo this month, it's the first time in the last 54 years (it snowed in Tokyo in November 1962)
13 degrees here in Nozawa , I have been in a t shirt .
I was going to mention the near record low temperatures later, so thanks for doing that!!!!
This also explains the unusual swings in temperature we've had in Japan over November.
While temperatures of 20+ degrees happen in November, maximums below 8 degrees are unusual.
So with the cold and high pressure over Mongolia, we CAN get cold temperatures in Japan, but since it's still November, there's plenty of warm air off to the south of Japan, and the Kuroshio current is still warm and close off shore.
Interesting to see that happen. That's a lot of cold air to play with...
It has to come from that direction, and with a lot of low pressure troughs coming through, that cold air is less likely to come towards Japan.
This is what I mean when I say that it's better if Japan doesn't get a single low pressure trough all season.
So the best case scenario is just northernly winds from a Siberian High's East flank without any lows being around to bring up warmer air.
On the flip side, areas of the arctic have seen temps +20C greater than average recently
That is a massive high pressure. 1085hpa
Yep, the two appear to be linked.
Sandy could you please explain how the weather patterns work for Zao Onsen? Looking at a topographical map it would seem the storm systems coming off the sea of Japan first hit the mountains of Mount Ashai/Mount Itoh. Zao is a lot further from the coast than say the Niigita resorts of Nozawa, how does it receive its 10+ meters of snow each year? Is it because it is further north? Thanks for helping out this weather noob
There's two ways Zao gets snow, both through gaps.
- Winds just south of due west, across to the north of Niigata City.
- A funnel that happens with a NNW wind, converging on Gassan mountain(it gets HUGE snow, and doesn't open until April), which is a peak higher than most of the surrounding mountains. The rest of the cloud skirts around and continues towards Zao.
- It also gets some snow off east coast lows
