Radar

[shuggee]

Does anybody know if the radar images from the likes of www.meto.gov.uk are in themselves not exactly a true representation of a live image? I was wondering if forecasters/meteorologists/quality control monitors, screen radar images before they are published to screen-out the likes of anoprop or miscellaneous unkown echoes?

According to the MO website on the link below, they process the radar feed for permanent echoes or reflections from hills and buildings, anomalous propagation (anaprop) which often occurs in anticyclonic conditions and the strong echoes produced when falling snow starts to melt to rain:

However, many have noticed that anaprop still manages to slip through their 'processing' until they manage to fix and exclude the erroneous echoes.

what Nick says is correct. Most if not all the regular anaprop causes will be known and filtered out but anaprop can occur for a variety of reasons and it may take the 'duty bod' a while to realise something is wrong at a particular time.
