  1. This is all because they have a high bringing in N easterlies which travel mostly overland with little to warm them up - the same sort of thing happened in the US not so long ago and didn't Houston get some unseasonably cold weather? and that is virtually on the Gulf of Mexico.

     

    In the meantime we have been getting southerlies, making it mild for the season - you just can't trust those damned jet streams at all.

  2. During the early hours we are likely to see an apparition of a sled being towed by 6 reindeer with a large fat white bearded man on board shouting out, Ho, ho, ho.'

     

    Then during the day fresh W to NW breeze - sunny periods & rain showers - Max +6C Min +3C and no snow for Watford.

     

    In the mid pm there are likely to be gusts of wind but this will be due mainly to the brussel sprouts with an alcoholic mist setting in late evening.

  3. Seems to be a duplication of threads here, so I will copy paste on here as well:

     

    What will they think of next? Although it's something I can't see the CAA approving in this country - the difference between this and the drones the police use is that at least there is somebody in control of it, albeit on the ground but at least somebody would be in a position to keep a look out for any potential hazards - telephone lines, power cables and other light aircraft which may be in the vicinity, together with the flight paths of commercial aircraft landing and taking off at airports. However with these they would be completely automatic, navigating by GPS and unless there is a sophisticated obstacle avoidance system built in able to detect and avoid obstacles which could be travelling at a speed at anything from nil to say, a couple of hundred mph at low levels, even a lot faster if the RAF are practising low level flying in the vicinity.

     

    I wonder if they will be fitted with transponders?

     

    However wouldn't it be great if they upgraded these machines to a capability of carrying a couple of passengers or so and their luggage - with the multiple rotors I expect they would be easier to fly than a conventional helicopter and short make short work of a family trip to the seaside without getting stuck in the traffic, though likely to be an air traffic controller's nightmare with all these things shunting around the sky, so perhaps not - we will just have to resign ourselves to that large car park called the M25 Posted Image

  4. One of the most amazing clips of film I saw in relation to the under ice environment of the Antarctic was when a flow of fresh melt water flowed from the ice surface into the sub zero sea beneath - the fresh water being heavier than salt water caused it to sink to the bottom, just a matter of a few metres but as it did so, it froze taking on the appearance of a thick cable, down from the ice to the sea bed.

     

    No doubt this phenomena his a name but unfortunately I do not recall it.

  5. NASA tweeting that fate of ISON not yet established.

     

    What ? Did it defy Physics pop down to the surface of the sun for a bit, before carrying on it's wonky trajectory.

     

    Interesting C3 imagery coming out now.

    C2 from similar timeframe

    Is that it at about 11 o'clock which seems to be a brightish spot with a bit of a tail pointing back towards the sun? but surely on its outward journey the tail would be pointing away from the sun.

  6. Worth noting that Mars has no large moon like Earth and if one recalls one of the things which makes our core what it is was the early collision that formed the moon.

    And no doubt the gravitational forces involved provide the energy to sustain our liquid core, as is believed to be the case with some of Jupiter's moons, whereas Venus which does not have tectononic activity and possibly a more solid core and no magnetic field to speak of does not have any moons.

  7. I go with the theory that since Mars is so much smaller than the Earth, about half its mass, its core cooled much quicker than ours changing it from a liquid into a solid - once the whole planet became solid, it meant that different sub sections could not revolve at a different rate to each other which is an essential part of maintaining a magnetic field which is developed through this interaction.

     

    Some also say that it may have been involved in a collision  with an asteroid some 4 million years ago which had catastrophic effects and that prior to this it was quite earth like.

     

    As the magnetic field dies away the planet was at the mercy of the solar winds which over time stripped a lot of the atmosphere away and a good part of that which wasn't stripped away combined with the rocks, for example the oxygen combined with the iron in the rocks, oxidising it, though water still exists there in the form of ice and that is why it became the 'Red Planet'.

  8. The answer is noNovember 1963 in the UK was very mild and exceptionally wet more like November 2009.This November looks like being close to average rainfall and maybe a touch below average temperature wise.

    As far as I recall it wasn't anything like as cold as '62/63 - big disappointment, mostly cloudy and wet - the nearest we came to a heavy snowfall at Watford was one day when we had a period of heavy sleet with large flakes but I don't recall it settling.

  9. Fantastic Knocker, they bring out the otherwise secret world of a glacier out into the open - mind you, sooner them than me - such expeditions can't be without hazard with the ice moving - so cold as well but what else would you expect? :)

  10. I'm sorry I posted it now but thought it might interest some people. I can't see any AGW propoganda in this at all but it's easily deleted if it offends some people.

     

    I'm getting a tad fed up with all this. The point of the post was basically the stunning photography which wouldn't have been possible without the melting and the moulins and ice-caves. Pathetic.

    Such a pity I would have loved to have seen it - remember Knocker, you can't please all the people all the time.

  11. Not really, as this was neither a hurricane nor a tropical cyclone by any stretch. A sad tragedy nonetheless, and as the article states, storms of the strength "Cleopatra" was are unusual in that part of the world.

    Not altogether - the Med has the propensity to whip up some good storms - the one referred to here was a double whammy where a south east gale caused a storm surge pushing the water back up the Aude whilst torrential rain on the hills around its catchment area pushed the water down, so its level had to rise.

    Cuxac is just about 5 miles of so from our village but fortunately we are slightly higher.

     

    A couple of hundred miles to the west and this current storm could have caused devastation in the coastal areas around the Gulf de Lion - reckon we got away by the skin of our teeth, as it was last Saturday morning we just had some rain but no strong winds to speak of and the weather did not clear up until we were half way through the Massif.

  12. Continuing the next leg of the journey, Issoire to Rouen - the journey continued cold cloudy with hill fog with visibility down to 50 metres in places above 500 metres but on the approach to Rouen the sky started to clear and temperature rose to a balmy 7 C.

    I agree with you about the way things change with height - I have had some interesting driving through the Pyrenees and as height is gained the vegetation changes as does the farming and in the Spring and early Summer part of what were the deepest Winter snows are about.

  13. We started off from Capestang about 1330 hours today and after an hour had reached the viaduct at Millau.

    The journey started off overcast with some rain which gradually cleared as we headed north. Still cloudy at Millau but it had died out and we had a temp of 13C.

    After about a further 50 miles or so the sky cleared greatly to leave us with stunning views of the sunlight on the rocks,fields and woods.as we progressed further and rose in height to the 1000 metre level we started to see patches of snow in the fields and at the temperature started to drop, upper single figures when we first hit the snow patches, then down to 5C and as it did the extent of the snow increases. It wasn't deep, say about 2 cms. It was still great to see in the sunlight and as we got to the 1100 metre contour it was more wide spread but alas soon after that we ran into fairly dense fog and a temp of +1C. I wondered whether the fog would just be restricted to the snowfields but no, it continued after we dropped below 900 metres and the visibility on really improved below the 600 metre mark and by the lifting into stratus, but still cold. As we descended the other side it did warm up to +4C but it had the typical appearance of a miserable cold November day in England.

    And it was only last Wednesday we were walking around the village with the temp in the low 20's.

    Roll on Spring - my old bones can't take it any more, though I must say the snow looked lovely.
