'Odd' flashes seen outside..
Strange thing happened about half hour ago, woke us up. 6-7 flashes, bright enough to show through bedroom curtains, (facing east). Perturbed me enough to log on and check for Sferics - none, apart from Dutch Coast, no cloud on IR Sat, and no radar echos.Long distance Lightning's the only thing I can think of?
Rising shelf cloud..
I was watching the clouds go by when something out to sea grabbed my attention.... there was a band of scud-like clouds to my east, forming at low levels and slowly rising. As I watched they began to form a more dense sheet which started to move my way. The rising motion intensified and the whole thing accelerated towards the shore. They have just passed over, resembling a shelf cloud with a swing in the wind direction to a SE'ly and moderate rain is now falling. If this had come from the N I would have said "Cold front" and not been at all bothered, but this has come from completely the wrong direction. Mid-level cloud still streaming N-S, and to my north it's pitch black, can still see pannus/scud hurtling along on a brisk easterly.... Any thoughts?
Strange funnel clouds & sheet Lightning incident..
Event 1 -I was kite boarding at St Andrews in Fife on quite a hot day but because the wind was very light I was paying more attention to the clouds about 3-4 miles away. It was when I was looking over St Andrews to the South that I noticed an almost pure white funnel cloud coming down from a dark base. This was over a field of Oil seed rape. Then a few moments later another came down to the right of it curving in the opposing direction. Once they were both down they appeared to 'join' together!
Event 2 -I was on a relatively short walk from the Capital of Shetland out to a small village to the west, weather at the time was: Wind: 25-30 knots with frequent hail and show showers.
About a mile out of town I was cutting through this valley following a track when a severe hail shower set in. The clouds were also very low or it seemed that way with me being on top and within them. As I was more than halfway up the side 'It happened' -without warning everything went brilliantly white, unable to see anything except for this hot light. At the same time there was a sound like when the electricity is turned up in a transformer. At first I thought I had been shot in the face with a flare as it was quite hot, and white like burning magnesium. But then I thought Im out here alone so it couldn't have been. My eyes were hurting a bit. The next thing I knew there was this massive rumble going through the valley and I was laying on the floor...
..this is a question that is baffling myself and all the people i have told. Last friday night at 23.30 the fish pond in my garden was full, at 7.30 next morning approx 100 gallon of water had disapeared. I checked for leaks and found none, i then refilled it to the top and it is still full. The pond is securly covered by a net,so nobody has syphoned water away. My question then is, is it possible for it to have evaporated? 100 gallon! almost half the water in it. Everybody i have told has said that it is not possible. The weather on friday evening did change, and saturday was a very warm day. I just wondered if it may have been a freak occurance? or is this a common occurance?
As of the 13th of December the evenings start to get lighter, but until the 21st (solstice) the mornings are still getting darker faster than the evenings are getting lighter.
From the 21st onwards, the evenings get lighter faster than the monings get darker, so the net day length still increases. However the mornings do still get darker until the 29th!
So, the Winter Solstice is not a day, but a 16 day period.
The same happens around the summer solstice, but for the summer, the whole thing happens over only six days? I am now trying to work out why the solstice period over the summer is a different length to the solstice period over the winter? I think is is to do with our lattitude.... can you help?..
Also discussed at-
It's the middle of night- but why is it so bright out?
And don't say cause its full moon Its 5 am, I thought it was 8am. I can't even see the moon as it's behind cloud. But its bright like midnight in north Scotland on mid summer's night. I can see everything to my horizon, the mountains etc. Anyone else notice this? Now the cloud is thin and patchy and the outline of moon was visible earlier. My brother remarked on this the previous night, and I had made the same observation then also. It was cloudy then as well, all be it thin cloud.I'm assuming its weather related, which is why I put question here, and I'm guessing it must be something to do with the thin cloud reflecting the light. Its actually got a bit darker now as thicker cloud is above now.
So any answers- or does it just seem like a normal full moon night to you?
Sleet falling from a clear sky..
About 15 mins ago, a sudden squall of sleet fell out of the sky, lasted no more than about 10 seconds. In these winds, its not surprising. But what i dont understand is that there are giant CB's passing to the north of me, but the wind is coming from the west and there is nothing to the west. I used to see this kind of thing a lot in north wales, and i always thought the mountains had an affect, but there are no mountains round here...so what caused this?
Magnificent Miraculous Mirages
Check these sites with magnificent inverted mirage pictures above the Arctic circle: http://www.islandnet...ry/artmirge.htm http://www.thulebage...a%20morgana.htm The first link gives a explanation of this phenomenon.
My nasty habit is to challenge and check. So I ended up with severe doubts about this explanation. Anyone wants to give it a try? (Warning: high-school-level physics involved.)
Mysteriously increasing dewpoint
I've got a strange one . While in Sardinia recently I spent two weeks in Alghero, in the northwest of the island (on the southern part of the little bit that juts out on my avatar photo, where the little black marks are). I used to listen daily to the metar from the nearby airport which lies about 5 miles north of the bay. Typical daytime observations were Wind E/NE 10kts, CAVOK, Temp 39°C, Dewpt 6°C. However, come night time, the dewpoint would increase noticeably, many times to 21 - 23°C, without any shift in wind direction, ie, still blowing from the land. It became very sticky and the visibility deteriorated dratically as mist formed. Come morning , the dewpoint would fall back again as it was the previous day.
What could cause this increase? Since the wind didn't shift and blow from the sea, it wasn't due to a influx of humid air from the bay. It happened night after night for over a week so it wasn't a one off. The only thing I can think of is that maybe it was due to trees. The area is densely populated with olive, cork, and mediterranean scrub. Could it be that at night time these all started transpiring water vapour, as trees do, or is there some other meteorological reason?
Temperature rises after dark
Having recently set up my weather station (not yet recording to the PC) I've noticed that the last few evenings the temp has dropped towards and just after sunset but then risen a degree or two during the evening. This doesn't seem to have been related to an increase in cloud cover so why does it happen?
Cloud breaks and pressure dips..
Today we've had a heavy and low stratocumulus overcast with aoccassional patches of drizzle (Ugh!) Also thoughout today the barometer has been falling. Between 18:00 & 19:00 we had a sudden breakup of the cloud layer and actaully saw some blue sky for a while before the cover reformed. At the same time there was a 'blip' in the downward trend in pressure, not large; but the pressure did go up about 0.5mb over a period of an hour before resuming it's downward path. Now this looks too good to be a coincidence; but why would the rise in pressure cause the cloud layer to break? Or is there an unseen third party at work here that caused both the pressure rise and the break in the cloud cover?
Loud booms- long distance thunder?
I can hear loud booms here - must be thunder but I cannot see anything on the radar and it's clear here. The last one was quite loud - could this be long distance thunder?
Possible 'St elmo's fire' report Basingstoke, Hants
I do believe I witnessed St Elmo’s Fire this morning at Roughly 0230 BST at my home in Basingstoke Hampshire during a severe Thunder Storm. After being woken up by my car alarm going off due to very heavy Hail and Rain I noticed a very strange sensation while trying to disarm the alarm and also noticed that the roof was covered in what I can describe as a misty blue looking gas hovering about 5 to 10 inches and a sound of needles dropping on a floor. The feeling I was getting in my body was a tingling sensation in the end of my fingers. The lightning at the time was only CC but was producing every 1 to 2 seconds so I would say the air was very electrified. What are your thoughts on this. At the time I was still half asleep But what I saw and felt I do believe was St Elmo's Fire.
Storm affected frogs?
I recall a really good thunder storm back in July 2000 (I think) when living in a place called Woodford Halse, half way between Daventry and Banbury. The storm, as most do, took place mid afternoon and I observed something really strange as I watched it approach from a west facing upstairs window.My back garden at the time had a decent sized pond in one corner, which over a few years had become heavily inhabited by frogs and toads.This particular afternoon, whilst watching the dark clouds appear in the distance, I observed over a period of about half an hour just about ever frog jump out of that pond and work their way across the lawn to 'hide' under bushes, under rocks, beneath the fence, in fact anywhere apart from in the pond itself. At one time I counted over 50 frogs all hopping in different directions away from the pond.
Now, I am fully aware that a number go walk-about after dark, because I used to watch them quite regularly, but never this many and definitely not during daylight hours. So.... I wondered if they either sensed the pressure change, or sensed the 'electricity' in the air as the storm rumbled closer and decided maybe that it wasn't safe to be in the water? The storm when it did hit was a cracker and having spoken to a local Torro man a few days after he informed me that it did spurn one or two funnel clouds too over towards Towcester.
This is a mystery that has been bugging me since so i thought it was about time that I seeked some expert opinions!
Tornado or not?
During yesterday morning's storms, some tiles got blown off my fiancee's roof in Cambridge, and the builders working on a roof nearby described a 'whirlwind' as being responsible. How can this be followed up to see if it really was? My fiancee described hearing a strange roaring noise when she was in the bathroom about 9.40, but thought it was the builders' tools, and it may have been that the tiles came down at a different time when she was out, anyway. Also, at about the same time there were certainly some very strong and unusual sounding winds at my house a mile or two away, but as I was also in the bathroom at the time I couldn't see whether they were anything other than strong gusts.
Ball lightning event or not?
Just wondered if anyone out there living in Eltham Greenwich Woolwich area heard and saw what from talking to others might have been some sort of ball lightning about 9pmish Wed night??!! Had curtains drawn at time, but room was lit up by amazing orange flash - like a camera flash but stronger and red/orange! Followed by the loudest explosion - like a mortar going off! No am sure was not a firework as spoke to a friend in Plumstead this morning who said he had been looking out of his window at around the same time last night and actually saw very briefly red/orange ball in the sky- which seemed to have fiery tail to it too - then fell towards ground before he heard the enormous explosion too - any ideas please..
Sudden large wind gust..
During a 10 min med hail storm 7mm dia. there was a 'cutting' noise coming from the sky. I was watching the hail through a window. The alarm went off on my weather station.....I thought must be sudden temp drop... but it stopped , then it beeped again. It was the high gust alarm set at 57 mph. I looked at the top gust and it was 67 mph. I looked back out of the window there was no visible ground winds but there was turbulance above the house. Now....i rushed outside after the alarm went off for the 3rd time only to see the anemometer whizzing around....really fast....but there was no apparent gusty wind at ground level.... this lasted for prob less than a minute.. whats going on? there was nothing visible in the sky, othere than hail and the base of a cb.
Very localised thunderstorms
When we first moved to Ireland I encountered a weather phenomenum that I'd not experienced in the UK, that of very localised electrical storms. We were living in West Cork, 2 miles to the north of Enniskeane. The area is rural and hilly.
In my expereince you can usually hear a thunderstorm coming, however these 'storms' would occur without any warning and would be characterised by one or two cloud to ground (or possible ground to cloud) discharges (one came down the telephone line and fried my PC :-( ). There was no rain associated with the event. After the electrical discharge you didn't hear the 'storm' passing into the distance, so the event seemed to be very local. Does anyone else have experience of localised electrical activity and does anyone know what might have caused it?
Did I see ball lightning?
I was wondering if anyone here has seen or think they might have seen ball lightning. Its something im particularly interested in but have never been fortunate enough to witness it first hand I think.. However there was ONE occasion when i was on holiday in the late eighties in Gran Canaria when i did see an odd red globe of light at night hovering for about 5 mins about 3km away above a mountain .. it wasnt a plane or helicopter Im pretty sure as it was quite diffuse and pulsing, but to be honest I really dont know..
Possible GLO event 10th Sept 05 S Essex
Intreresting thing occured about 20 minutes ago and I'm curious as to what happened.I was watching a storm to my west/south-west when a bright blue ball(or at least it looked that way)with a tail about 3-4 times the size of it came out,it then faded it seemed about a second later,about 2 seconds later there was a massive discharge inside the cloud that lit up the entire structure,could these two incidents be related by any chance and in what way??)
If you have any similar threads you started or that you know of, that youde like to add to this please do so..
Unexplained cold on Bodmin Moor..
Whilst driving around Colliford Lake on Bodmin Moor one winters evening many years ago, we encountered a very strange and to date unexplained phenomena. The OAT according to our car thermometer fluctuated between -0.5 and 0.5c from Penlan Eating House all the way east across the moor until we reached the right hand turn off for Colliford Lake. Once on the road round the lake the OAT fell to a pretty constant -1.0c and it was clear by the car headlights that a good frost was taking hold. We continued the slow uneventful drive around the lake and then about 1.5, maybe 2 miles from Bolventor we noticed the car thermometer was showing an OAT of about -4.0c and it was falling steadily as we looked. All appeared pretty much the same outside, clear skies, no mist/fog, excellent visibility in fact - and we were not in a dip or near a water source. Unfortunately the road at this point was very narrow and only suitable for one vehicle, so given the icy conditions we felt it prudent not to stop despite our growing curiosity. I did however wind down the window to test the air and it certainly felt the -5.0c the car thermometer was now indicating. My overriding thought however was the thermometer must be throwing a wobbly, so to test things I squirted the front windscreen with water. To our amazement the widescreen froze almost instantly after the first passage of the wipers and the ice became almost impossible to clear fully until the heater had been going full bore at it for some time. Then liturally a few seconds later my hubby says the temperature is rising again now and within about 2 minutes it was back to -1.5c ish. By this time we had probably travelled about 1/2 mile at the very slow speed we were doing, but now we were able to pull over in a passing place and try to take stock of what had happened. I'd seen the thermometer bottom out at -7.7c, my hubby saw -7.9c, so we'll call it -7.8c as a fair average. We both got out the car and had a good look around (well as best you can in the blackness) but as before all seemed very normal. Upon getting back in to the car we noticed the temperature starting to fall again, -2.0c initially, then liturally within 60 seconds or so -4.0c. Hubby got back out of the car and said "its certainly getting rather chilly dear" (or words to that effect) and again within a minute or so the temperature was -6.0c. That was the lowest point that we witnessed because I just had to get out and feel the air for myself. It was incredible, it felt perishing, despite no wind at all. We both just stood there either side of the car, looking across an icy bonnet at each other in total disbelief. After about 2 minutes we got back into the car to find the temprature had risen to -4.0c, within another 2 minutes or so it was -1.0c and that is pretty much were it remained during the rest of our drive to Bolventor. Over a very welcome hot chocolate at the Jamaica Inn we tried to rationalise what had occured. We both felt a faulty car thermometer was the most likely cause and had we not gotten out of the car at some point we'd probably have convinced ourselves of that fact. However we both felt the air for a couple of minutes at one stage and as previously said it was perishing. What appears to have occured (thought it sounds absurd) is a pocket, pool, lump (call it what you will) of very cold air crossed the Moor in a generally south to north direction at an estimated speed of about 5-10mph. How big it was we have no idea, where it came from or indeed where it went also remains a mystery. The most annoying thing however from our perspective is neither of us had sufficient knowledge of the weather at that time to actually follow this up. We did check the local press for several weeks after the event, hoping someone might report a similar incident, but no such luck. Sadly neither of us can remember an exact date either, but we both concure that it was early Feb 1996, perhaps around the 3rd, 4th or 5th. The one thing we are thankful for though is that we were together and we both witnessed almost exactly the same, apart from the slight discrepancy over the lowest value seen. Had this event occured whilst I was alone I would have almost certainly dismissed it as a faulty thermometer, because no way would I have gotten out of the car on Bodmin Moor in the dark on my own.
(Another!)..was it ball lightning?
...as we sat, watching out of the window... suddenly there was a large purple ball of lightning that looked to be right outside the window! It was there for maybe 2 seconds and then there was the most huge explosion I have ever heard in my life! We all screamed...
Fork lightning glow
During the amazing display of fork lightning last night i noticed a strange glow in the sky after a big fork would release its energy and disappear, the sky would be lit up in a white colour for a short period of time after the lightning appeared. Was this something to do with the lightning?
One of the weirdest unexplained things that ever happened to me goes back several years. Coming back from the pub in the pitch dark down a very quiet rural and badly lit road, I realised I had to answer the call of nature. It was a very clear night, with a myriad of stars in the sky, and no street lights to interfere with the view. So, I'm standing there looking up at the sky, as you do, when suddenly there is a sound above my head. Now, the only way I can describe this sound is to liken it to that of an artillery shell. It sounded quite low in altitude, and quite loud, a pronounced "whoosh" without any hint of an engine tone....
