Apologies if this is an old topic, but I've been looking at a few lightning detector maps (http://www.upminsterweather.co.uk/te..._lightning.htm, http://www.isleofwightweather.co.uk/live_storm_data.htm, http://meteocentre..com/lightning/eurnw_sfuk.gif, http://www.blitzortung.org/Webpages/...en&subpage_0=3) and they seem so be inconsistent in their stormlightning positioning.

Right now, 13 July 2013, 1730 GMT, spherics on 350 kHz are fairly strong in central north Norfolk. The lightning maps show storms around the Humber Estuary or North Sea or south Lincolnshire.

Only blitzortung.org shows lightning even close to rain radar shown on Live UK Rainfall (http://www.netweather.tv/index.cgi?action=radar;sess=) i.e. south Lincolnshire. Presumably the rainfall is where the storms are, so blitzortung.org seems to be the most accurate.

As a non-meteorologist but RF/propagation engineer, how come it's so difficult to position a storm from its spherics? Or is there something I am ignorant of that I should know about before making such comments?

Anyway... which lightning map websites are the most accurate for the UK?

Thank you.
