Mini Ice Age? (Page 40) duncan124: The PV has dipped further south and appears to be sucking in air from North Africa. This wobble must be connected to the large number of tropical storms in the East. Sir Loin: I can't hack satellite pics of the Arctic from here, can you get one of the polar jet stream so I can identify exit streams that would be deepening low pressures over USA? duncan124: According to Nullschool the Jetstream is bunching up over the Indian Ocean and all down the east side of Africa as far as Madagascar Sir Loin: That's a fairly major departure from normal. I'm in the Southern Hemisphere and a jetstream exit here will have the effect of deepening any surface low pressure systems by increasing their cyclonic (clockwise) Spin. Depressions go anticlockwise up north but it seems the jetstream exits don't have an opposite effect. duncan124: At 250 hPa the story is more complex and the Jetstream looks more like its normal wiggly self But there is a lot of it and there are oddities such a breach in the stream from the mid Pacific across North California , Washington and Canada which looks just like a road and might have something to do with the long PV gap a short while ago. Over eastern Australia there is a slight anti clockwise movement near where the fires were. duncan124: Dr Cohen in his AER blog explains that he no longer thinks a zonal wind reversal is likely and that the PV is " disrupted " with its bullseye over the Barents-Kara sea. Where the sea ice is known to effect the PV. His models predict a colder winter in Siberia and North america where there might be a Canadian Warming of the Stratospheric PV https://www.aer.com/science-research/climate-weather/arctic-oscillation/ It seems the Arctic Oscillation is in full swing and the increase in wind maybe associated with the start of Solar Cycle 25 (Post deleted by Sir Loin ) Sir Loin: Meanwhile in NZ it's pissing down with parts of the South Island isolated by floods and landslides. I've just seen an idiot tourist find out you can't drive a rental car through 3 metre deep water. Sir Loin: There's a large blocking High to the East while a series of cold fronts sweeps in from the West bringing heavy rain, thunderstorms and strong winds. My new roof is getting a great workout. duncan124: It has been North Atlantic weather here in the UK and next week its is predicted that the storm that had been forming near Greenland will arrive with a lot more wind. As I mentioned a few posts above there has been several storms quickly near Greenland and Canada which is normal but when they bunch up the question is what is causing them This is fairly normal December weather if warmer and milder then most. We have been lucky here in Europe. duncan124: 26 spotless days again, so we could be expecting a Sunspot soon. The stats for 2019 point to the next Sunspot appearing any time now. The question has the Sun seriously changed since the times of the great record stretches without spots surely now must be given some serious consideration. (Edited by duncan124) Sir Loin: The climate alarmists aren't gonna support that idea. No money to be made out of blaming sunspots duncan124: But all the same, the Sun isn't the same as it was. It is far weaker and has been producing Sunspots regularly even if fewer than before. duncan124: Iceland has experienced a mojor storm and another, or the rest of that one is heading for Europe tomorrow and Friday. SWE reports. Yet more from the same source? duncan124: SWE reported this from the start and has more about these storms from the North Atlantic. https://www.severe-weather.eu/mcd/violent-winter-storm-underway-iceland-getting-worse-mk/ duncan124: This year is now in the record league as an Also Ran at 31 days stretch but around the top five for overall total already. " Spotless Days,Current Stretch: 31 days, 2019 total: 268 days (77%)" Spaceweather. http://sidc.be/silso/spotless ...for other years duncan124: The PV is growing in strength and a quick look on Nullschool reveals it is sucking in air from across Europe down to North Africa with a long tail across the globe to Florida. Meantime it is also dropping air over Alaska and Washington with a long tail across the Pacific. This must be making the north of the west very much colder and while the feed from Europe is making the PV bigger. We should expect colder weather I believe. Meantime NASA has decided that the Solar Minimum will be at its deepest in April 2020 -/+ 6 months and that the next cycle will be much like the present one. But as is happens that we could be facing going in to a new solar cycle with a much colder world then we had when leaving the old cycle. It will be trending cold now for maybe the next year with maybe more storms as we have just seen. Sir Loin: If there's a long tail over the Pacific, I would expect that to add to the cyclonic spin in low pressure areas in the Southern Hemisphere, this would encourage cyclogenesis at first unless the tail moved on and allowed anticyclonic flow at jet stream level. Possibly a causal factor in the early beginning of our cyclone season? duncan124: Yes, the PV rotates east and its Pacific tail heads west. This is the tail that leaves the PV and where it comes out of the PV and heads the other way it is spilling air across North America. Sir Loin: That's really too far north to affect us down here. Shame because the Met Bureau in Aussie is forecasting a heatwave of greater than 50C in he SE of the country already ravaged by bushfires duncan124: I think the Climate Change protests in London significantly helped the regime to stay in power by activating corruption in London which still thinks to control all organised activities and not face the fact that the Gay corruption of the old order is not supported by enough of the public to be able to return to its old strength. Not facing the fact that where people were living was getting colder when demanding attention for concern about the temperature is such a serious mistake that the very small Mr Johnson will no doubt re-arrange the Governments official statements about it. duncan124: Australia has always had heat waves like that and Portugal has had as many bush fires without anyone caring or indeed the temperature being that hot. | Science Chat Room 3 People Chatting Similar Conversations |
