It is an Excel quirk (more details below). Your username "February 1978" defaults to 28522.

You are 11th in seasonal comp and 18th overall and 6th in April.
I'll change the format to put your name to February 1978 in future, as shown below.

Thank you for continuing to compete

More on Excel quirk -

Each date in Excel is converted to a number as per below, each cumulative day since 1st January 1900.
So the username February1978 was converted into a number based on the date 1st February 1978.

 

 

Ok, understood, thanks for replying

If it's too much trouble to change it, that's fine I know what to look for

Thanks

Hi,

I'm probably blind, but I can't see my entries? I've entered all except December.

Thanks

Light/moderate wet snow in Tadley

The band does seem to be weakening somewhat

[South West and Central Southern England Regional Weather Discussion 01/12/2018 Onwards]

Sleety rain now in Tadley

[South West and Central Southern England Regional Weather Discussion 01/12/2018 Onwards]

Looking at the radar, seems a small really heavy patch of rain/snow between Salisbury/ Winchester/ Andover

What's the metoffice latest charts showing anyone know?

Rain/snow seems to be intensifying, East Somerset/Wiltshire

This should mean it's more likely to be snow (as the melting cools the air locally)

Is the 0.87 factor just a good rule of thumb? I'm thinking pressure doesn't increase / decrease in a linear fashion through the depth of the atmosphere. Would an extreme (say) 950mb or 1050mb surface pressure test the 0.87 factor quoted?

Just interested, as I've wondered about this previously.

For those who know any fluid dynamics it's just hydrostatic balance...

dp/dz = - (density * acceleration due to gravity)

dz = - dp / (den * g),        density of air = 1.225 g/m**3, g=9.81 m / sec squared

So change in height = change in pressure / (about 12) - a factor of about 0.83?     (give or take pressure units!  Pascals ---> mb)

The density of air varies quite slowly at sea level, so the factor should be pretty constant...!

Absolutely BB.The snowfall of a lifetime, 20ft drifts, tropical Weymouth was cut off for 3 days. The rain quickly turned to snow (not as forecast) on Saturday night and by lunchtime Sunday it was a winter wonderland.

As an 8 year old at the time, these are memories that will never fade. All that from this...

Relevant to those learning to understand that it isn't all about super strong HLB and/or about cold uppers taken in isolation.

As a 9-year-old in Taunton I remember this vividly too (see my moniker). Fence high snowdrifts, villages cut off for days - and it was completely unexpected / unforecast. I think it was just Devon, Somerset and Dorset - Cornwall missed out. Started snowing lunchtime Saturday, and over 18 inches by the morning.
