  1. Ossie please see below a table I drew up a while ago... Kind regards ACB Decade Mean days p.a 0c or less; Years with 5 or fewer days 0c or less; Years with 10-19 days 0c or less; Years with 20-39 days 0c or less; Years with more than 40 days 0c or less; Years with 10+ days 0c or less 1998-2007 3.0 8 0 0 0 0 1988-1997 6.8 4 3 0 0 3 1978-1987 15.4 1 4 3 0 7 1968-1977 7.1 4 3 0 0 3 1958-1967 14.0 1 3 1 1 5 1948-1957 10.9 5 3 2 0 5 1938-1947 16.8 4 3 2 1 6 1928-1937 7.8 5 2 1 0 3 1918-1927 7.1 5 3 0 0 3 1908-1917 8.4 5 2 1 0 3 1898-1907 10.1 2 7 0 0 7 1888-1897 17.9 1 2 4 0 6 1878-1887 16.8 3 2 3
  2. DJI closed at 7114.78 down over 250 points or 3.41% on the day. FTSE (depending on Nikkei/Hang Seng) may fall as low as 3750 tomorrow. Even if Iceberg's pessimism turns out to be wrong (i.e. a severe recession but not a 1930s style slump) there may well be at least another 9 months or more of falling markets. A bottom of perhaps 5000-5500? Perhaps 10-12 years before 14000 is recorded again? regards ACB
  3. I was at Junior School in the village of Eglinton not far from 'Derry and on the coastal plain of Lough Foyle. I can certainly recall a cold month with wintry showers but rarely amounting to much. I suspect that we were sheltered to an extent from north/north westerlies by the Inishowen peninsula. regards ACB
  4. Yes indeed...the relative ease by which snow was cleared in the 19c and early 20c is something of a recurrent theme in the contemporary press reports quoted by Mr Data. My guess is that in pre-National Assistance times (pre 1929?) the authorities were able to call upon a pool of unemployed working class men to clear the snow. regards ACB
  5. Surrey 22/4 1979 and late April Oxford 1981; about 1" 9am on both occasions. April 2008 south London? regards ACB
  6. That occurred to me...from the Victoria History of Middlesex (before 1850): "In the late 18th and early 19th centuries the spread of villas along some of the lanes branching off High Road was more noticeable than the growth of separate hamlets...The residential nature of most new building gave late-18th-century Tottenham the appearance of an extended, semi-rural suburb rather than a town. Industry, apart from brick-making, was virtually confined to riverside mills until the construction of a lace-factory in 1810 and a silk-factory five years later...As late as 1859 the authoress [sic] Mrs. J.
  7. "1300s; What was this "droghte of Marche" that Chaucer refers too? Is he suggesting that it was normal, or at least common, to have a very dry late winter/early spring with "Zephirus with his sweete breeth" suddenly turning up sometime in April?" 1. Impossible to know in any detail now whether 13thc late winter/early springs were particularly dry. 2. However dry easterlies are, I believe, more prominent in Feb/March than other months in the south east. 3. Whilst 20thc data for the south east shows February to be either the driest or one of the three driest months on average there is little evi
  8. Many thanks Mr D. Do you have the date, location and record maximum for October 1985 please? regards ACB
  9. If you mean the highest temperature ever then 28c at Sumburgh Haed on 6th August 1910. regards ACB
  10. Kevin, almost as striking is the frequency of daily maxima above 80f in the preceding three years. Assuming that those temperatures were recorded from, say, mid May to mid September (about 120 days), that means approximately 22-29% of days recorded maxima of 80f or more! regards ACB
  11. aldergove.docaldergrovetext.docPH recently complained that NI summers had recently been ‘poor’ and that with GW he expected better summers and specifically summers with maxima exceeding 90f… 1. What do we mean by a ‘good summer’? 2. The dangers of reliance upon memory alone; 3. The implications of AGW for regional seasonal weather patterns. 1. In NI it is customary to define summer as including May (it is often the driest/sunniest month although never the warmest) which I have included in the table attached. There are, I suppose, three main factors in judging summer weather in NI: temperature,
  12. The terms 'Manley' and 'Hadley' refer to the late Professor Gordon Manley (died 1980) and to the Hadley Centre, an establishment set up by the Met Office to undertake research into climatology. Manley, a highly respected climatologist, made it his life's work to establish an instrumental record of average monthly temperatures in England. He originally chose to use data from Oxford and the Lancashire plains to give a record of western central England. Oxford was chosen because the Radcliffe Observatory had records going back many years. In 1974 Manley published the second of 2 papers in which h
  13. Indeed nor have we experienced a January as warm as January 1921 at 7.3. Whilst January 1916 is by some way the mildest on record it is far from being the most anomalously mild compared to the then applicable CET: January 1796 at 7.3 was 5.1c above the 1761-1790 mean of 2.2... I imagine that barring some unforeseen calamity it is almost impossible for us to record a January CET as anomalously mild as that of 1796: 'even larger teapot' and warm SSTs notwithstanding a January CET of 9.3 would imply average maxima of about 12c and average minima of 6.5c. To equal the relative anomaly of 1916 (+
  14. January 1795 at -3.1 is the coldest month in the entire CET series with only 1684 (-3), 1814 (-2.9) and 1740 (-2. coming close. The mean January CET for 1761-1790 was 2.2 (a full 2c below the 1971-2000 mean and a potent reminder of the severity of many winters during the 'Little Ice Age'). Thus January 1795 was an astonishing 5.3 below the 1760-1791 mean. Nonetheless even though January 1963 at -2.1 was a full 1.0 less cold than 1795 its' anomaly from the 1931-1960 mean of 3.5 was an even greater 5.6. The CET for January 1796 was 7.3 (joint second mildest with 1921) and the 5th coldest mont
