    2.1c

    heavy, heavy rain.

    worst kind of weather imo.

    zero flakes of snow or even sleet.

     

    so enjoy the snowcover whileyou  guys can!

    sorry to be the bearer of bad news, you giys fair better than me so have half a chance however surely i'd be seeing some sleet if most of you fellow low lying people were to see snow further north....?

    anyway, good luck but don't expect too much... Sorry!

    It is raining here too. I wonder if it will turn to snow. It started as rain yesterday too. Milder air must have moved in.

  2. Beautiful morning here, nice and still and fresh clear Arctic air.

     

    After TMax will be interesting to see what this trough can get up to as it clears SE.

    Looks a little more organised than the precip forecast would suggest. One to keep an eye on the radar for..

    Edit - add strat chart to compare to the satellite image. Other than the band coming through, it shows the huge RW trough very well. attachicon.gifEUMETSAT_MSG_RGB-airmass-westernEurope.jpgattachicon.gifecmwf100a12.gif

     

     

    Spied this - made me chuckle - Every media outlet today..

    Is that fax chart showing another band of precipitation moving down/in from the west/northwest?

  3. What phase of the QBO is expected this winter?

    Can you have rising and falling angular momentum (GLAAM) in a strong El Nino? Rising and falling GLAAM is good for cold in winter according to Glacier Point.

    The analogues pointed out by Glacier Point for this winter and 1972, 1982 and 1997 - with 1997 and 1982 the closest matches for this year. Can anyone explain the significance of the extratropical interactions observed in the analogue years for winter? Thanks if anyone can offer some input.

    It looks like we are now moving into a westerly phase of the QBO for this winter unfortunately. The figure for August was 10.97. Last winter we had a negative (or easterly) phase of the QBO. http://www.esrl.noaa.gov/psd/data/correlation/qbo.data

    Strongest El Nino since 1950 on the way: An El Nino climate event is under way that could potentially become one of the strongest events since 1950.

    That's according to a new Met Office report which says that 2015 has already seen the warmest start to any year on record.

    It also outlines that El Nino is one of three key climate patterns that could lead to changes in our global temperature.

    The event occurs when the waters of the Pacific become exceptionally warm and distort weather patterns around the world.

  5. HI Guys,

     

    I released an article yesterday linking strong heights in the Arctic during July, to cold UK winters. Also there seems to be a link to Strat warming's as the years linked had either a sudden stratospheric warming (major) or multiple minor warming's. All the information within can be found via the link but I must say going on my findings, 2015 certainly looks very interesting.

    1995 had one of the longest spells of hot summer weather on record and yet that winter was also one of the best I can remember. I was 7 years old that winter and remember that summer and winter very clearly. A relative of mine got married that summer and I remember very very clearly the longevity of the hot weather that year and then the cold winter that followed. But I hope the article is right that it could potentially bring a cold winter too.

  6. I just had a thought. Just this week past there have been about 4 category 3/4 hurricanes in the Pacific due to the El Nino. This will be sending warmth right up into the atmosphere. Doesn't this mean that it will warm the tropical stratosphere and decrease the likelihood of stratospheric warmth this winter? I say this because the thermal gradient between the tropical and polar stratosphere impacts on the strength of the vortex does it not? Don't you need a really cold tropical stratosphere and a warm polar stratosphere to prevent the vortex from strengthening? Therefore a warm tropical stratosphere isn't a good sign if you want a weak vortex in winter? So can anyone tell me if the current El Nino which is warming the tropical stratosphere will impact on us come winter? Anyone? Thank you. I know this isn't the media thread but Alex Deakin has just mentioned the warming of the atmosphere from the developing El Nino and the fact that it is warming the atmosphere so I thought it would be relevant to this thread in this instance. I am going to put in a link to the video here: http://www.bbc.co.uk/weather/features/34159718

    It would be great if chionomaniac or Glacier Point could answer so that everyone then knows the impact (if there is any).
