[h=3]Historical Note - Other Thames Freezes
This is not intended to be a definitive list, and is based on reported weather conditions from agricultural records where the freezing of the Thames was recorded on most occasions in London.
The intention is however to demonstrate that severe weather conditions such as described below were not unique and occurred from time to time on a reasonably regular basis.
Freezes occurred in 1963, 1953, 1947 (the coldest February ever), 1940, 1895-6, 1893, 1880, 1857 (Source: Leslie Ward ('SPY' of Vanity Fair) Autobiography, page 17 where he recalls well that an ox was roasted on the Thames at Eton), 1821, 27 December 1813 - 27 March 1814 (Frost Fair 4th Feb 1814), 24 December 1739 to early March 1740, (Frost Fair Christmas 1739 - February 1740), 1708, 1688, 1685, 1684, 1683, (The winter was 'intolerably severe' (John Evelyn), Frost Fair), 1665, 1649, 1608, 1607 and 1564. There are earlier records of freezes also back to 1100AD.

[h=4]February 1963 The end of January saw the return of the cold weather after a brief respite. By Friday 1st February the ominous comment in Gordon's diary had indicated that the really cold weather was returning. Gordon also mentions that frozen water supply pipes were a problem. "7 Hanley Close site... very badly frozen from main." Apparently attempts were being made to thaw pipes by passing low voltage current through them, but not with total success.
On the 3rd February the diary entry reads "Siberian weather. Bad forecast. Car badly affected by salt, rust stains." Indeed any car that had been used regularly on the permanently wet, salty roads, would have suffered badly, the salt having a very corrosive effect.
Old oil heaters had been put back into service - though many were probably past it - often by those who had no idea how to use them safely. The result was many fires were started either when a heater was knocked over, or was refilled whilst alight, or perhaps had been left unattended in a loft in an attempt to defrost frozen plumbing. In any event the fire brigade were kept busy!
Priority in the distribution of coal was given to steam trains carrying supplies of food, coal, oil and petrol.

February 5th 1963. Weather Map The weather map for 5th February 1963 showed a deep depression to the south west of the UK.The Air Ministry forecast for much of England, Wales and southern Scotland was for cloud with moderate to heavy falls of snow at times, Rain was only forecast for the West Country, with some sunshine, the rest of the country was in the grip of a cold air flow from Europe. In London the minimum temperature in the previous 24 hours was -3°C with a maximum of 1°C. As this was in the centre of London, temperatures would not have risen above freezing out of town.
The efforts of "meals on wheels" - deliveries of hot meals to the elderly - were much appreciated to say the least and the help also extended to taking buckets of coal to those who had run out. It was clear that many old people were suffering severe hardship as a result of the shortage of fuel. This was at a time when smokeless zones were being introduced despite inadequate supplies of these fuels being available.
Militant union action aggravated the situation with 'work to rule' orders to the staff of power stations. The result was power cuts that closed cinemas and theatres, darkened streets and traffic lights. It became necessary to carry a torch and also to keep matches and candles readily to hand at work or at home.
On February 5th a thaw was forecast in the west, but a blizzard resulted with a very low depression moving up from Madiera. On 7th February the temperatures had warmed up, but only to about freezing and this led to more problems at night as the pavements became 'glazed' with ice from daytime melted snow. These were extremely dangerous conditions for pedestrians.
On February 8th at Vansittart Road Recreation Ground photographs were taken of what seemed to be the long awaited thaw - pictures below - but by 10th February Gordon's diary records yet another frost warning and north easterly winds with more snow at midday. That evening, the BBC broadcast a TV programme about 'The Big Freeze'.

The whole of the following week, from Monday 11th February through to Friday 15th, a very slow thaw alternated with night frosts such that by the end of the week there was still snow lying. There was more light snow on 20th February in the morning and again the next morning but nothing substantial, and Gordon's garden was by now almost clear of snow near the house, apart from a pile created when an attempt was made to clear the garden paths six weeks earlier on 5th January!
22nd-26th February was half-term for the Grammar School boys who had a great game of bicycle hockey on the backwater by the school boathouse. By now the ice was almost 6" thick and so there was no danger of the ice cracking, but in mid-stream it was a different matter where areas of clear water still remained with very thin ice around them.
Still there was no significant change in the weather and come 24th February freezing weather had returned by day as well as hard frosts at night. A few days later, however, by the 27th, the daytime temperature reached 40°F (4°C), warm enough to be noted in Gordon's diary and for the snow to have disappeared from all but the most sheltered and shaded areas.

افت فشار آب طی روزهای اخیر در شهر قزوین​


متاسفانه با شروع فصل گرما و نیاز مبرم به آب، در شهر قزوین نیز، طی روزهای اخیر افت ناگهانی فشار آب در مناطق مختلف مشاهده گردید.
به گزارش خبرنگار ولایت؛ مجید برخورداری، سرپرست روابط عمومی شرکت آب و فاضلاب قزوین طی سخنانی در گفتگوی اختصاصی با خبرنگار ولایت، در این خصوص گفت: بر اساس آیین‌نامه تشکیل شرکت آب و فاضلاب، مصوب مجلس شورای اسلامی فشار آب تحویلی به مشترکان از کنتور باید دست کم 2 اتمسفر بار باشد.
وی بیان داشت: با توجه به اینکه میزان فشار آب مشترکان قزوین در اغلب نقاط شهر به طور معمول در حدود 2 و نیم تا 3 اتمسفر بار می‌باشد چنانچه با ا‌فت فشار آب روبرو هستند مشکل آن از سوی شرکت آب و فاضلاب نیست.
سرپرست روابط عمومی شرکت آب و فاضلاب قزوین درخصوص چگونگی رفع مشکل افت فشار آب در منازل پیشنهاد کرد: از آنجایی که به طور معمول افت فشار آب ناشی از استفاده چندین خانوار از یک کنتور می‌باشد بهتر است برای رفع این معضل کنتور مجزا درخواست شود و یا اگر در طبقات سوم به بالا افت فشار آب مشاهده می‌شود می‌توان با نصب مخزن ذخیره آب در مجتمع‌ها مشکل را حل کرد.
برخورداری خاطرنشان کرد: برای رفع مشکل افت فشار آب گاهی اوقات لازم است قطر لوله‌های ورودی ساختمان از یک دوم به سه چهارم افزایش یابد که در این راستا مشترکان می‌توانند با تماس تلفنی با مرکز ارتباطات این شرکت به شماره 122، درخواست خود را مبنی بر فشارسنجی از سوی کارشناسان، اطلاع دهند.
وی ادامه داد: پس از اعزام کارشناسان به مناطق دارای مشکل چنانچه فشار آب آن‌ها از 2 اتمسفر بار کمتر بود از سوی شرکت آب و فاضلاب اقدامات لازم بعمل می‌آید و چنانچه استاندارد فشار آب رعایت شده باشد برحسب مشکل موجود توصیه‌های لازم به آن‌ها صورت می‌گیرد.
سرپرست شرکت آب و فاضلاب قزوین در بخش دیگری از سخنانش مهم‌ترین عامل افت فشار آب را، مصرف بیش از حد برشمرد و افزود: به طور معمول افزایش دما افزایش مصرف آب را هم به همراه دارد و این امر منجر می‌گردد فشار آب شرب تا حدودی کاهش یابد که از شهروندان تقاضا داریم الگوی مصرف را رعایت نمایند.
ایشان برخورداری استاندارد سرانه مصرف آب برای هر فرد را یکصد و 50 لیتر در شبانه‌روز برشمرد و افزود: متاسفانه در شهر قزوین سرانه مصرف آب شهروندان در شبانه‌روز بین 250 تا 300 لیتر است که در این راستا تغییر الگوی مصرف و استفاده بهینه از آب امری ضروری به شمار می‌رود.
وی با اشاره به کاهش نزولات آسمانی و میزان بارندگی در سال‌های اخیر تصریح کرد: با توجه به اینکه آب شرب استان از چاه تامین می‌شود در حال حاضر به دلیل عدم بارش مناسب و نزولات آسمانی، سطح آب قابل شرب در سفره‌های زیرزمینی تا میزان قابل توجهی کاهش یافته که این امر نیز در افت فشار آب منازل تاثیر بسزایی بر جای گذاشته است.
سرپرست روابط عمومی شرکت آب و فاضلاب قزوین: تغییر الگوی کشت در کشاورزی را از دیگر دلایل افزایش مصرف آب عنوان و اضافه کرد: در حال حاضر بخش قابل توجهی از آب موجود در سفره‌های زیرزمینی برای کشاورزی استفاده می‌شود چرا که کشت دیمی محصولات کاهش یافته و کشاورزان اغلب به کشت محصولات پرآب روی آورده‌اند.
برخورداری ادامه داد: تا 20 سال گذشته چاه‌های آب شرب قزوین در سفره‌های زیرزمینی با عمق 70 متر حفر می‌گردید در حالی که اکنون برای رسیدن به یک حلقه چاه و دسترسی به آب شرب مناسب باید بین 180 تا 270 متر حفاری صورت گیرد که این امر، بیانگر کاهش حجم آب سفره‌های زیرزمینی است که رعایت الگوی مصرف آب را گوشزد می‌نماید./ ی

Winter of 1962–63 in the United Kingdom From Wikipedia, the free encyclopedia
Jump to: navigation, search

Deep snow near Burrow-with-Burrow, Lancashire, England, January 1963



Snow in Lancashire, January 1963


The winter of 1962–1963 (also known as The Big Freeze of 1963) was one of the coldest winters on record in the United Kingdom.[SUP][1][/SUP] Temperatures plummeted and lakes and rivers began to freeze over. In the Central England Temperature (CET) record, extending back to 1659, only the winter (defined as the months of December, January and February) of 1683–84 has been significantly colder, with 1739–40 being slightly colder than 1962–63. However, the winter did not rank so highly in Scotland for its severity as it did in England and Wales.
[h=2]December 1962 The beginning of the month was very foggy, with London suffering its last great smog before clean air legislation and the reduction in the use of coal fires had their full effect. A short wintry outbreak brought snow to the country on 12th-13th. A very cold easterly set in on 22 December as an anticyclone formed over Scandinavia, drawing cold continental winds from Russia. Over the Christmas period, the Scandinavian High collapsed, but a new one formed near Iceland, bringing Northerly winds. Significant snowfall occurred as the air mass moved south and parts of the South of England in particular had heavy snow late on 26 December (Boxing Day) continuing into 27 December.[SUP][2][/SUP] The cold air became firmly established.
[h=3]29–30 December 1962 On 29–30 December 1962 a blizzard swept across the South West of England and Wales. Snow drifted to over 20 feet (6.1 m) deep in places, driven on by gale force Easterly winds, blocking roads and railways. The snow stranded villagers and brought down powerlines.[SUP][2][/SUP] The near-freezing temperatures meant that the snow cover lasted for over two months in some areas. Snow lay to 6 inches (15 cm) depth in Manchester city centre, 9 inches (23 cm) in Wythenshawe, and about 18 inches (45 cm) at Keele University in Staffordshire. By the end of the month, there were snow drifts 8 feet (2.4 m) deep in Kent and 15 feet (4.6 m) deep in the west.
[h=2]January 1963 January 1963 was the coldest month of the 20th century, and the coldest since January 1814, with an average temperature of −2.1°C.[SUP][3][/SUP] Much of England and Wales was snow-covered throughout the month.[SUP][2][/SUP] The country started to freeze solid, with temperatures as low as −19.4 °C at Achany in Sutherland on the 11th. Freezing fog was a hazard for most of the country.[SUP][4][/SUP]
In January 1963 the sea froze for 1 mile (1.6 km) out from shore at Herne Bay, Kent.[SUP][5][/SUP][SUP][6][/SUP] The sea also froze inshore in many places, removing many British inland water birds' usual last resort of finding food in estuaries and shallow sea. The sea froze 4 miles out to sea from Dunkirk, and BBC television news expressed a fear that the Strait of Dover would freeze across.[SUP][2][/SUP] The upper reaches of the River Thames also froze over,[SUP][4][/SUP][SUP][7][/SUP] though it did not freeze in Central London, partly due to the hot effluent from two thermal power stations, Battersea and Bankside: the removal of the old multi-arched London Bridge, which obstructed the river's free flow, and the river embankments, make the river less likely to freeze in London than in earlier times (see River Thames frost fairs). On 20 January, 283 workers had to be rescued by RAF helicopters from Fylingdales, where they had been snowbound for several days.[SUP][2][/SUP][SUP][8][/SUP] The ice was thick enough in some places that people were skating on it,[SUP][2][/SUP] and on 22 January a car was driven across the frozen Thames at Oxford.[SUP][2][/SUP][SUP][8][/SUP] Icicles hung from many roof gutterings; some of these were as long as a metre (3 feet, 3 inches).
[h=2]February 1963 In February 1963 more snow came. It was also stormy with winds reaching Force 8 on the Beaufort scale (gale force winds).
A 36-hour blizzard caused heavy drifting snow in most parts of the country. Drifts reached 20 feet (6.1 m) in some areas and there were gale force winds reaching up to 81 mph (130 km/h). On the Isle of Man, wind speeds were recorded at 119 mph (191 km/h).
