    As per title, can the weather boardsies help?

    Currently there is a fire at a nuclear power plant in Ukraine and fighting including 'heavy weapons' fire.

    News is reporting the fire to be in a training room but the potential for a Chernobyl type event here or at another nuclear plant in Ukraine is real.

    It would be good to be on top of the wind/weather systems in relation to radioactive fall out

    I heard something about this not necessarily being like Chernobyl because of a difference in technology, but that aside, the next five to ten days look as though low to mid level wind patterns will start out northwesterly (from the northwest), and will shift gradually more to northerly and northeasterly.

    Also of note is the fact that colder weather is setting in, and it is due to become very cold by middle of next week, could be around -15 C overnight and -7 C in daytime in much of the conflict zone (if it still is a conflict zone then). High pressure is building up over Russia and Siberian air is moving in the direction of Ukraine as a result.

    This cold and largely dry pattern with some snow at times in the next few days will persist for almost two weeks then a cold rain or wet snow sort of regime seems likely to replace it in second half of March.

    I was studying in Germany in '95 and carried out a field study into the effects of precipitation patterns following the Chernobyl disaster on soil radioactivity in southern Germany. Where rain had fallen in the weeks after the disaster, gamma radiation from Cs-137 (half-life 30 years) in the soil was notably higher than in the areas where it hadn't rained. Where no rain fell, radioactivity was almost completely absent.

    So it's not just wind direction but also precipitation patterns that are things to look out for.

    Suppose it would be useful to know about soil temperatures and how mushy the ground will be or is freezing will harden it up and how long it would take to harden up etc........


    in relation to tank movements

    I would imagine if they were going to blow the power plant in some kind of false flag then the middle of next week with easterlies would be the most likely time to do it with lesser effect to Russia. How depressing to be even contemplating all this.

    Have a weather station?, why not join the Ireland Weather Network - http://irelandweather.eu/

    Not the big issue it was being made out to be, God knows they have enough big issues already.

    It was a training facility in the grounds of the power station, not any of the reactor building, that was on fire.

    Insanity that they would even think of firing on the complex though

    Possibility it might change hands several times like some other places

    The situation in general got me looking at ideas about full-scale nuclear exchanges and where the worst radiation clouds would be, in my part of the world, it is not what I first imagined (concentrated over large population areas) but a strong concentration would likely occur over the northern plains states into south central Canada because that's where many of the ICBM launchers are located (North Dakota has the most). So in my own case, we are rather on the edge of that and it would depend on how weather patterns distributed the fallout later (once the temporary disruptions to the atmosphere subsided). And of course it would be a one-way street to nuclear winter at that point. Morbid thoughts, I wonder if I would be better off to drive as far away as I could (towards Yukon would make sense) or go into the target zone and get it over with quickly. At my age I suppose neither is a good choice.

    I don't think a full-scale nuclear exchange would end human life on earth, by the way. Pockets would survive in the northern hemisphere, and there's no reason to think many nukes would be exploding south of the equator or even near the equator, so as the circulation would tend to take a lot of the fallout into the arctic eventually, the southern hemisphere might survive almost intact, and so might some equatorial regions. I think it would be almost a complete annihilation of the northern temperate zones and further north, over a period of time, as the survivors starved to death in the non-technology aftermath. Only a few people would be well equipped to survive and many of them would be older single males with no chance to procreate, thus ending the strain by attrition. Some might say good riddance to all of us, I suppose.

    But in this nuclear winter, might we have an increased chance of snow?! Swings and roundabouts if so.....

    Well the bottom half of the atmosphere (which is where most nuclear fallout from non-weaponized explosions would remain) continues to flow mostly southwestward across the Black Sea in the case of the southern facility and across western Ukraine for Chornobyl, and in fact there will be some unseasonably cold weather most of this month in the entire region including the Balkans, Turkey, Greece and the eastern Med. One wave of more extreme cold is underway now and another one occurs about a week to ten days from now. The 510 dm thickness contour makes occasional appearances over Ukraine in this time frame and even heads into Turkey although it degrades to 516 dm once there. This will be 10 to 15 deg (C) below normal in some of those southern climates. We'll be hearing a few stories about snow in Athens and Istanbul and higher parts of Israel too.

    Sometimes part of this colder air mass shears off and tries to move west into southern Germany and France. If there was to be a high radiation crisis in the conflict zone, some of this would advect west at times but it doesn't look sustained enough to become a major hazard for western Europe, central might be a different story.

    My hope is that this ends sooner rather than later. It seems to me that Putin's strategy is to punish eastern Ukraine where he seems to think the de-Nazification is most needed, probably that translates to the observation of some perceived atrocities over the past few years against Russians that he associates with cities in that region, which is perhaps why the shelling and military activity around those cities is perceptibly greater so far than in other parts of Ukraine. I think he has the massive convoy buildup near Kyiv mostly to pin down a large part of Ukraine's armed forces there, so they cannot fully deal with the events in eastern Ukraine. This tells me that perhaps he does not plan a major incursion into Kyiv at least for a while, and hopes to get a favourable settlement (favourable to him that is) so he can retreat into the three enclaves that he claims should be in Russia.

    However, trying to read this guy's mind is perhaps beyond anyone's ability, particularly mine.

    vegetation takes up radioactive caesium into leaves. This would be released into the air for dispersion by fire.........

    The convoy build-up has been analysed by those who understand these things and the consensus now seems to be that the column stalled 25k from Kyiv is the main resupply convoy for about seven Russian battalions (about 70k men) which were to be the encircling force for Kyiv and need to be resupplied daily which is not happening.

    Mud glorious mud or Rasputitsa"Mud Season" in Ukraine.

    The convoy is mainly made up of supply trucks/tankers with about 100 tanks for protection which are mostly being ignored by Ukrainian forces because they can't go anywhere. There is even some speculation that the Ukranians can now win the fight because of this stalled convoy. No fuel, bombs and bullets to fight with make it impossible to take Kyiv, even if there were not 500k angry civilians with plenty of guns and very sophisticated NATO weapons waiting for them.

    Putin hit the staging base base near Polish border last night for all NATO equipment coming in to resupply the Ukranians so he's inching closer and closer to doing something really stupid. More desperate each day Ukraine holds out. The Ukranians have been taking back towns behind the main Russian convoy.

    The main reason for Russia's success in the South appears to be a mix of better terrain and carpet bombing. Dry and almost desert in Crimea so no issue with mud and poorly maintained equipment. The Russians use Chinese tires on their military vehicles and these have been shown to be badly degraded; ie poorly maintained. This has been seen many times by OSint people, who are fantastic.

    Unfortunately, all of this probably makes it more likely that Putin will try to use a nuke. He seems to be under some pressure in Moscow now.

    There is an interesting series of tweets from someone who claims to be receiving briefings from a senior FSB leaker. He believes that Putin would be stopped if he tried to use a nuke, that it's not a "one red button" thing, but the responsibility of a committee of sorts. He is claiming that Putin has been very badly briefed by all around him, that a corporate culture which was aimed at pleasing the boss, gave overly sunny assessments of how an invasion would progress, how strong his own army was. He offers this as an explanation for the absence of any major air attacks by Russia ie the planes are not in good nick.

    On a positive note, the leaker has also suggested that Russia's nuke stockpile might be in a similariily poor state of repair since the enriched plutonium in the warheads must be replaced every ten years. They're struggling to change tires.

    Well we have lived a charmed life in terms of avoiding the big nuclear disaster that could have happened several different times over the nuclear era, I'm sure you are all familiar with some of the times where events big or small could have gotten us into the nightmare. This is no doubt the most concerning time since the Cuban missile crisis which I vaguely recall hearing about as a kid, just after a few years of monster Soviet nuclear tests in their arctic, and feeling apprehensive about it all (at the age of 12-13). This is a murky business because we can't really tell whether Putin has lost some of his legendary smarts, or is just misinformed and looking for a way out of an unexpected mess, although surely anyone could have told him this would be the result. We cannot even be 100% sure that Biden is playing it straight either, U.S. political forums are always buzzing with rumours about Hunter Biden and close associates of other "uniparty" politicians, notably Mitt Romney, the friendliest Republican now that McCain is gone.

    The alternative is Trump who has his own balance sheet where in some ways he might do better with this file and in other ways he might be even more worrying. Joking about false flags involving China might appeal to his base but as somewhat of a neutral I would say it sounded strange coming from somebody who could return to power, if you or I said it in a bar that's one thing, but this is on a different level.

    It makes me wonder, since we cannot really trust too much of what we are told by either politicians or intelligence services nowadays, since they don't seem to be working in our interest, how could average people like us create fact finding agencies that could report those things that are currently only the subject of rumour or speculation? Should there be as many secrets in the world as we seem to tolerate? I get why some military info is classified but some of the other things are very much in the public interest, and the bottom line is, if elites actually operate on assumptions that involve the general expendability of billions of unconnected people like us, then should we not have some way of pushing back rather than being herded around like cattle for their exclusive benefit? I'm sure the people of Ukraine feel like that, big powers absent-mindedly debating in the abstract what should happen while their lives are turned upside down and for no apparent benefit to anybody, I'm sure Ukraine is not going to be absorbed willingly into a greater Russia, and any attempt to do that would probably end up in years of violence if it didn't lead faster to Putin's removal from office. That seems like one way out, but then we are stuck with all the murky business unexplained and back to the other files where we are gradually losing what freedoms we used to have.

    Getting back to the actual subject of this thread, unfortunately the lower to mid-level atmospheric flow will be pointing more towards western Europe than the Balkans by end of the week, another potent shot of very cold air is due into Ukraine around Thursday-Friday, but any wafting radioactivity that might occur for any reason would increasingly be likely to travel towards central and parts of western Europe. Eventually a more zonal flow would develop and then any such hazards would shift back towards parts of Russia and countries further east. That looks like being delayed to very late March or some time in April and only for intervals, not all the time. A southerly flow would be good in that it would be aimed at Moscow which might serve as a deterrent to anything risky or foolish. But that doesn't seem to be very likely for sustained periods. There are patterns where that can happen but I don't see those in the near future or even medium term.

    As the crow flies, The Kremlin is 700 km northeast of the Chornobyl plant and the Belarus border is just 22 km. An initial southerly and then northeasterly flow would be the best as it would dose both countries with maximum effect. Plenty of rain along the way to make sure nobody in those countries gets missed. A nice high over the Caucuses and a low over the Baltic should do the trick. War over.
