I'm not a meteorologist at all, so perhaps theres a simple answer but
can someone explain where the south easts rain has gone the last few years? What has stopped it getting here or have the weather systems not formed in the first place? The reserviors not far from me are getting worryingly low, is there any decent rain on the horizon so to speak? B2003 |

Stronger Azores High..... more high pressure to our South.
Thunderstorms used to be common here in the Summer. Very rare now. --------------------------------------------------------- "Boltar" wrote in message oups.com...

I was walking into Canterbury along the river and noted that there's so little water flowing that you would be mistaken for thinking that it's the middle of August. The mill race near Pound Lane is dry and there was only a trickle of water over the weir. Ducks are again unable to swim some parts of the river! (BTW. only 28.4mm here so far this month and 460.0mm for the whole of 2005.) -- Jonathan Stott Canterbury Weather: http://www.canterburyweather.co.uk/ Reverse my e-mail address to reply by e-mail |

Same just over the Estuary. Golf course is on clay but, like my garden, the
dryest I have ever seen it in Dec/Jan. Dave |

I'm not a meteorologist either but this winter dry spell is probably down to
natural variability and next year we could be inundated with rainfall, overall though there is a pattern of ever increasingly drier summers, and this applies to much of England but is more enhanced in the south-east. ________________ Nick G Exe Valley, Devon 50 m amsl "Boltar" wrote in message oups.com...

Going on my records since 1989, there seems to be relatively little change in the annual rainfall totals, it just seems to be shifting in when it actually falls throughout the year, i.e., drier spring & summers; wetter autumn and winters. I believe this fits in with earlier models showing the effects of a warming climate on the UK. If the climate continues to warm then this shifting of rainfall pattern is predicted to get more extreme. ________________ Nick G Exe Valley, Devon 50 m amsl "Graham Easterling" wrote in message ...

Yes, slightly drier spring & summer here as well. The rainfall here has always been very seasonal, but is even more so now. I believe this fits in with earlier models showing the effects of a warming climate on the UK. If the climate continues to warm then this shifting of rainfall pattern is predicted to get more extreme. I agree. Also what I find interesting is the warming over the last couple of decades here has been slightly greater in summer than winter. This counters the argument that warmer winters are just down to the lack of blocking conditions. Apparently CO2 emisions are apparently increasing at a record 3.5% per annum. Partly because the politicians in the developed countries are attempting to meet emission targets by exporting energy hungry industries to the 3rd world. Looks like bye bye polar bears.

Most of it seems to have come up to Scotland. Over the last few years there
seems to have been substantial increases in rainfall totals particularly in northern Scotland. Its my impression that there are an increasing number of Highs over the southern UK leading to increasing frontal activity over the peripheral areas to the north much of this activity seems to be much slower moving leading to much higher daily totals: eg over 46mm yesterday. I would appreciate comments on this perception from more experienced and informed experts in this group. I have been trying to make comparisons on my recent data with longer term data from Met Office stations nearby but could not afford the £1000ish charge which the Met Office were trying to get from me for monthly temp, rainfall, and wind data from just one site over a 10 year period. Certainly local perception is that there is a lot more heavy prolonged rainfall as well an increasing frequency of severe gales and storms than were common over the last 40 years.
