da dove hai preso questi dati?
Sono impressionanti. Alcuni miei amici sono stati a Sapporo due settimane a sciare, hanno detto meno neve degli scorsi anni, ma comunque tantissima (ovvio, per come siamo abituati noi).
Di certo io ho seguito un po' gli spaghi per quei luoghi e le temperature non sono state sotto media, anzi.. Per quel che ho visto
"la putenza l'è nagòtt senza el cuntroll"

molti son visibili qui
In Jacuzia raggiunti quasi i -60°, con un picco minimo di -57° a Deljankir e Ojmjakon.
In Islanda raggiunti quasi i 15°, con temperature diffusamente sopra i 10°, fin sui 13°!!

In Canada invece ecco le straordinarie foto della tempesta "bomba" di neve che si è abbattuta in Terranova (St.John ha stabilito il nuovo record di totale di neve precipitata in 24 h, con 76 cm!):

Hello , be carefull with JMA data of snowfall exemple Shirakawa
normals 81/2010 気象庁|過去の気象データ検索
Historic 気象庁|過去の気象データ検索
Problem : All Numbers of daily snowfall of JMA amedas automatic stations are the sum of hourly positive differences and a lot of them are wrong
check for exemple this (Nozawa Onsen mars 2019
気象庁|過去の気象データ検索snowfall total of 27 march (8cm ) shows the problem, if you check hourly data and temperatures :
2nd half of the day 6cm with temperatures > 8° :
気象庁|過去の気象データ検索
During 2/3 days long huge snow events, the problem is opposite : Snow compaction of previous dozens of cm minimize the difference who is used, even with a hourly sum
I follow japanese snow data since many years ...
and i was shocked the day i discovered the "méthod" ->
(and they use it since 80's !! )
since that day i never use JMA snowfall data , I prefer their snowdepth numbers , the only problem with snowdepht is their use of the max of every périod for exemple midnight of a date and 1 hour later for next day if they are the highest of daily data of thoses 2 days .
For snowfall i use "snowjapan" ski reports, they don't overestimate
and i 've build .xls files of 5 snowest places of Niigata prefecture via theses links
/
exemple of multiyear (1995 to 2019 )
--
( 2018 = 2018/2019 ) snowfall totals of 2 times a day MANUAL measures, observations from 01/12 to 31/03 but snow ids not common out of this period
and i follow that too (Matsunoyama is the last line of daily reports ) http://www.city.tokamachi.lg.jp/sosh...ng/01yuki.html
for other files
**********
I agree this year japanese snowdepht numbers are terrible under 1000m , nothern Japan is at low level too but the difference is not so great .
i've posted here about some places https://forums.infoclimat.fr/f/topic...omment-3197385
and here Giappone 2016-2017
-> where i've joined a complete file tonight of Sumon/morimon data
