[February CET]

I think it is up to 4.1 based on the 12z GFS run

[February CET]

from the met office...

October 1926.

The mean CET for the 1st to 15th

was 12.41C; the mean CET for the

16th to 31st was 4.04C - a difference

of 8.37C.

[February CET]

Thanks Muppet... Very interesting...

I see that we are currently at 0.7c for the month and that the GFS predicts the rest of the month at 6.4c... Is that a record difference (if it were to come off?)

good question.

does anyone know the record difference between first and second halves of a month for cet?

either cold to warm or vice versa?

[February CET]

I have set up a page that looks at the HadCET so far and then looks at the GFS forecast for the rest of the month and produces a prediction of the monthly cet.

as it stands it is forecasting 3.4c

you can follow its progress as it updates with every GFS run every 6h at

[The lowest pressure reading recorded in the UK]

will this go over the next few days?

the London value may do??

[Snow Watch And Models]

i recently compiled this page with 500 hPA maps from the main models and also snow risk maps.

hope it helps someone!

[Control, Mean Operational?]

pattern spotting with low res?

trends are easier to see?

any ideas on whether the green graph line is the best to follow?

[Control, Mean Operational?]

thanks Paul.

and out of just the graphs, is the green line usually the most accurate?

[Control, Mean Operational?]

thanks for your help. very kind.

I feel more clued up.

[Control, Mean Operational?]

thanks.

with that map I don't feel as if I'm getting as accurate data.

am I?

firstly I'm eyeballing where the place is, as opposed to entering a place name and secondly its not to 1 decimal place.

or is it all about resolution?

how easy is it to make that data available in graphical and tabular form?

that would be fantastic.

also just noticed that it is not for more than a day or two, rather than 16.

[Control, Mean Operational?]

thanks, I'm guessing

control is low res

mean is average of low res so is low res too

operational is high res and is the one to track.

ps I have a net extra for this month

[Control, Mean Operational?]

ah. I see.

and the control data on the ensemble graphs are taken from low res charts.

[Control, Mean Operational?]

thanks again. what do you mean by resolution?

accuracy? if so why is there a high and low res?

[Control, Mean Operational?]

great that makes sense.

thanks.

what about the operational compared to the mean?

the operational is supposedly more accurate too?

[Control, Mean Operational?]

thanks, I'm a bit of a novice.

what is it then?

ie how does it differ from control?

[Control, Mean Operational?]

yes, I do mean the green line on the graph.

I get the mean is the average of all the runs, the control is the line without any warm or cool adjustments but I still don't follow the green line.

sorry and thanks.

[Control, Mean Operational?]

I have looked at the help sections and also the excellent pdf guide to the ensemble graphs.

many thanks for producing those.

however I could only see explanations for the mean and control.

what is the operational line please?

[Data From The Ensemble Graph?]

is the max and min the high and low runs in the ensemble?

[Data From The Ensemble Graph?]

i don't understand the idea of having a max (with error margin), min and average for a particular time of day?

eg at 00:00 16 days in advance, the max may be 6.8(2.6) min is 5.4 (2. 8 and average is 6.8 (2.6)

how do these numbers relate to each other for midnight?

[Data From The Ensemble Graph?]

that's EXACTLY what i was after. thanks you very much.

A suggestion would be to see the predicted highs and lows for each day in one table, rather than having to click on each separate day.

Many thanks!

[Data From The Ensemble Graph?]

thanks, I was after the raw data used to plot the ensemble graphs for a certain location.

eg the data for this graph

netweather.tv/index.cgi?action=ensviewer;sess=

[Data From The Ensemble Graph?]

I've just really got into these ensemble graphs and maps, so apologies for a rookie question.

Is there somewhere that gives thee raw data for the ensemble graphical data?

I am a NW extra subscriber if that gives me access at all.

thanks in advance

[Uk Historic Isotherm Map?]

thanks, i can't see those Interitus, can you please post a link?

I'm guessing it's these?

http://www.metoffice.gov.uk/climate/uk/anomacts/

I was after a 1*C isotherm interval rather than 2*C, but thanks anyway.

[Historic Max And Min To 0.1c]

sorted.
