Could anyone direct me to suitable places to find daily rainfall figures for September 1980 for a station in (north)(west) London ?


http://www.metoffice.gov.uk/media/pdf/t/3/Sep1980.pdf

tells me that

"during evening of 20th, band of heavy rain and thunderstorms moved northwestwards from west sussex across south midlands and Wales"

and

http://www.metoffice.gov.uk/climate/...rackstorm.html

says 20th September 1980 tops the list of the 5 wettest days in Bracknell with 70.8mm

but I don't know if the storms hit London.

I ask as I am interested in the modelling behind the overflowing of my local sewage works into the Thames and the "typical" rain year used includes September 1980 :

Version AB of the response mentions that the list of storm discharges has been updated to include storms in September 1980 and then doesn't actually list any in that month !

Go to http://www.metoffice.gov.uk/archive/british-rainfall and select
1980. Download and try a search by place-name otherwise just wade
through the data from page 24 onwards - the Thames Water Authority area.
Look for the highest daily fall in right hand column. A quick glance at
hard copy here suggest the action was to the west and south-west on the
London area.

Nothing of note in Epping for that date.

The rainfall on 20 September 1980 is our all-time highest 24 hr (09-09)
total on record here in Wokingham. We had 71.6mm. I do have a list of the
falls on that day for other stations in this area, with Yateley Manor School
being the highest with 84.3 mm. Other values over 70 mm were 72.6 mm at
Reading Road, 71.8 mm at Sonning Farm, 70.8 mm at Beaufort Park. There was
quite a sharp cut off to the east and west, with Slough Ragstone Road having
24.8 mm and Inkpen having 27.4 mm.

The rainfall in my area of East London (8 miles east of the City) on that date, as measured by staff at City of London Cemetary (E12 5DQ), shows there was 0.2mm on 20th. And 8.1mm recorded the following day. Nothing out of the ordinary

In the the 24 hours up to 2100 on Sunday 21st September 1980, the rainfall was 54.9 mm at Fleet Hampshire. Rain arrived around 2000 on Saturday 20th and become 'very heavy with thunderstorm between 2200 and 2300'. Rain followed for the first part of the night.

Approximately 55.0 mm fell at Guildford, Surrey in the 24 hours up to 0900 21st.

Worthing recorded 94.5 mm, with apparent little flooding whereas nearby Brighton only received 8.5 mm which demonstrates the sudden cut off from the rain area.

There is an article in the WEATHER magazine from sometime in 1981 or 1982 which does a case study on the above event and also 14th April 1981 (Horsham deluge) and 2nd June 1981 (Worthing deluge).

The Hampstead weather station had its wettest day of the month on the
16th, with 10.7mm of rain. So if there was rain there on the 20th, it
can't have been that much.
