ROLLING YEAR AVERAGES

Post by darrog » Mon Nov 01, 2010 9:13 pm

I'm sure that you all do this (and a good subject for the 1st birthday to get the GW/CG debate going) - is to keep a rolling year of averages.

I started out in 2007 and have temp figures from August that year, hence the first full year of figures that I have is Aug' 2007 - July 2008 and then just roll on month by month.
I know that you all keep these figures.

Anyway for that first year I have a mean temp' of 9.82c with rainfall of 1136.2

Move on to the most recent figures of Nov' 2009 - Oct' 2010 and the figures are:
Temp = 7.933
Rain = 960.7

Rain as peaked at 1433.0mm (Dec 07 - Nov' 08) and I expect that most recent figure to drop significantly next month when the 317.2mm for last Nov' drops out.

The temp peaked at 9.84c (Sept' 07 - Aug' 08)

However, the temp as never been so low. Obviously this is going to be a cold year and that mean temp' goes up if a month is warmer than the corresponding one from the previous year - but the trend as always been a downward one apart from the odd month.
That's 3yrs of going down.

A trend or what?

What is the lowest/highest that anyone else as recorded?

Ummmm ... no I haven't kept rolling year records. :oops: It was enough work keeping manual written records and summarising a calendar year! I haven't had my new weather station for a year yet!

Darren
I am a bit lost with your rolling averages ?

How do you do it ? or do you mean "the year so far" compared with the same timer last year ?

Paul - take a look at the bottom of page 11 of this months COL - you'll get the idea.
'Rolling year' is my term, but football managers sign a rolling one year contract, so it seems fairly apt.

As stated above, my (anyones) most recent rolling year will be Nov' 2009 - October 2010.
Obviously we will have records for a calendar year eg: 2007, 2008, 2009, but a rolling year is the most current 12 monthly period.

for what it is worth I also work out 'the year so far' ie; Jan - Oct', but that is quite different.

Hope that helps, but look at page 11 of COL and it will quickly make sense.

There were two terms that you used that sent a chill down my spine:
1.) Spreadsheets
2.) giving tasks to do.

re No.2 i fully understand and sympathise.

its one of those things that is easy if started and then continued with when you first set out recording something - but more time consuming if done retrospectively.

For either yourself or anyone else the reason that I first mentioned it was simply for comparison with my own and others records and the peaks and troughs of warm/cold + dry/wet

I have added all my monthly spreadsheets into one big yearly sheet, then all my yearly sheets into one BIG 12 year sheet - I think my computer may overload when I ask it to produce some graphs !

Still looking into the best way to show rolling stuff

(not to many tasks have been left for me 1. Order new fence panel . 2 Pick me up at 6pm - should be able to manage both)
