Equivalent of a monsoon in hail here just now - noisy!!

No sign of any let up in the cold air anytime soon and the charts for 01/01/2010 show little sign of that pattern changing. We have solid thick frozen snow now everywhere. If there is more to follow then the anticipated continued freeze for the end of this week then there will be seemingly no let up and travel won't get any easier. Plenty of cold. http://www.meteociel.fr/modeles/nogapse_cartes.php?&ech=18&mode=1&carte=1

Can someone please explain the Three Letter Acronyms used on the model threads and also what the different charts represent. I am not completely daft but basic terminology explanation would help us 'lay' readers dip into this thread. Presumably one is for air temps at a certain height = potential for snow. And another is for precipitation. If any one is patient enough to do this would be appreciated as i cant understand why folk are arguing between different charts validity or strengths or weaknesses.

Snowing here in Livingston. Its not heavy just a steady fine falling, if you can imagine an overcast day when there is a fine drizzle in the air as opposed to rain - its as if this is the water type except its frozen and falling in the tiniest flakes.

Plenty of BIG FAT SNOWFLAKES here in Livingston - temp sitting at 0 degrees too . Let it snow, Let it snow, Let it snow..

http://radar.weather.gov/tropicalwx/satpix...tl_vis_loop.php This is a good one for watching the system come through..

London apparently getting melted with lightning according to the detector. Its interrupting my viewing of the golf! Where I am as usual overcast cold.. In this pic some interesting cloud formation over London and South East, also to North West of Mainland UK there is a strange looking bank of cloud that looks like it is rolling over itself?? http://www.metoffice.gov.uk/satpics/latest_uk_vis.html

Quality - replies at last - thanks Chris Kold Weather and Brick Fielder - these were the posts I was looking for. Did not know the Azores high affected USA so profoundly, that La Nina alters upper level winds and Hurricaine formation is interesting too. In regards to AO surely it is positive - wet as hell and trade winds kicking off.. la nina weather already being tracked for its impact perhaps here... http://nsidc.org/research/projects/Serreze...ntemporary.html Btw Picked Lorenzo deliberately as a user name because it is one of our storm names this season.. That AMO link is Doctorate level stuff! Brilliant -going to take my novice brain some time to compute all that.. Can anyone do a list of all the different oscillations or is there a good globe graphic of these. Surely they are all interconnected its just a case of statistical modelling to prove it.. So another wet windy winter... seasonal temps above average then a much colder one next year? Whats the main factor in how our winter will unfold? This report is excellent also especially for SSTs.. http://www.cpc.noaa.gov/products/analysis_...s-fcsts-web.pdf

Not to surprise anyone on here - current conditions where I live.. Rain in many formats - Monsoon type rainfall, clinging drizzle like clouds at ground level. Heavy Cloud around 15 degrees - wish an electrical storm would blast the mugginess away. Now its gone all dark on one side of the sky as what could be a thundercloud barely moves overhead. I love summer!

Hi Folks, My first post on here and look forward to hearing from fellow weather freaks. Well atleast thats what I get called. My meteorological knowledge is strictly amateur and I enjoy reading these pages and others online esp, the noaa sites. Can anyone give their thoughts on La Nina / El Nino and the effect it has on our part of the world - it seems that we get drowned with wet weather each time this cycle completes. Also I have wondered about whether this weather system is part of a larger global system and what effect it has on NAO if any. No one has proven a link - but the amount of water El Nino dumps into our hemisphere must do something?? As for our current weather - will the beginning of the Hurricaine season drag all the wet weather out into The Atlantic and mean some SUNSHINE - or will these Hurricaines track back North East and slam into Britain end July / August. Any thoughts or answers !!
