Default WMO Climatological Normals data?

Is this data still available to purchase, or better still, is it online?

A lot of my anomalies are based on this series which is for the period
1961 - 1990. What I like is it is listed my the 5 digit wmo numbers, so
I know it represents the precise location I have been decoding the
synops for and I would like to update to the latest (higher) averages.

Many thanks

Keith (Southend)

I put your subject line "WMO Climatological Normals data" into Google
and it came up with some possibly helpful hits.

You might find some useful data he

Unless it's recently changed, I believe the standard period being used
for comparisons by the MO for UK data is still 1971-2000. That's now
lagging quite a bit, of course. It's probably too soon for them to be
using 1991-2020, but it's surprising that it isn't 1981-2010.

Thanks John,

One thing I did find earlier, which is in the 2nd link you posted was
this statement, which makes me think they haven't produced a new version:

"However, for the purposes of historical comparison and climate change
monitoring, WMO still recommends the continuation of the 1961-1990
period for the computation and tracking global climate anomalies
relative to a fixed and common reference period."

It certainly highlights how the planet has warmed when using these and
also the May anomalies then don't look that extreme -0.8 to -1.5°C
around the UK.

Here's the link to my data I've just uploaded to my website which is
based on the 1961-90 averages from the wmo clamatological normals.

http://www.southendweather.net/euroav3.html

With C.O.L. we have just updated to the 1991 - 2020 averages, infact I
keep a rolling 10 year ~ 30 year mean 1971-2000, 1981-2010 etc...
Perhaps we should keep to the original data as the wmo are?

Another intersting statement:

Warming is not ubiquitous across the contiguous U.S. in either
geographic space or time of year. Changes vary from season-to-season and
month-to-month.

"For instance, the north-central U.S. Temperature Normals—for those in
the Northern Plains and Upper Midwest—have cooled from 1981–2010 to
1991–2020, especially in the spring. The South and Southwest are
considerably warmer. Normals were also generally warmer across the West
and along the East Coast. Precipitation-wise, the Southwest was drier;
wetter averages emerged in the U.S. east of the Rocky Mountains,
especially the Southeast in the spring."

I also have Met. 0. 856c
Tables of Temerature, relative humidity, precipitation and sunshine for
the world. (Europe and the Azores). It's old as the data period for most
is 1931-1960, I assume some of the war years were missed?

Tell me about decoding synops, please.
Why and how do you do it?

I just looked it up but I can't follow the accents on Youtube, then this caught my eye:

https://www.youtube.com/watch?v=wl_FFK_HbjY
the Met Office used to be a good site until I began to suspect it of telling lies. Until I can get to Exitdoor I will not be sure. What is true is that they still don’t want to publish the news that their charts are capable of telling us much more. Why ever not?

The warm fronts for example, indicate a volcanic eruption has started. The accompanying cold front is the first proof of fake weather. The warm sector; what can that tell us but the location of the eruption?

In the example given above the location is likely Indonesia: Sinabung most likely but that premise is subject to the warm sector in actuality. I have no idea if the set-up is taken from a real life model run, or just something made up in the classroom to show to students on the spur of the moment. They got the location close enough that it can be verified if they put up the date.

If it was a little to the south and east it might have been that bongo in The Congo whatever it is called. Nyiragongo lava flow engulfs hundreds of homes, ash rising up to 13.7 km (45 000 feet) a.s.l., DR Congo: https://watchers.news/2021/05/23/nyi...2021-dr-congo/

45 000 feet is quite an eruption. I would have been onto that like a stabbing, if I was still following the weather like I used to. If it followed a different path of fronts, Sinabung would become elsewhere and had it used a cyclone rather than an anticylone Etna or what's the other eitie?
