Weather forecast back
Posted: Fri Oct 12, 2018 4:33 pm
My weather forecast is back online at http://weather.bnellis.eu/forecast/ (English) or http://weather.bnellis.eu/Greek/ (Καιρική πρόγνωση).
I apologise for the week without a reliable forecast. This was due to a Florida State University website, which normally provides a great deal of international weather data. Unfortunately, there was an erroneous software change, which appears now to be corrected. Note that this problem had nothing whatsoever to do with the recent terrible weather in Florida.
In order to provide a reliable forecast, the software which I use relies on data from seven different sources in various parts of the world. These are the same data that are used by, for example, the US National Weather Service and the UK meteorological office. Of course, my PC cannot compete with supercomputers but I am able to do the same by restricting the input data to a radius of up to 2000 km and, above all, calculating it for a radius of, say, 20 km from my own weather station data.
I am frequently asked how the limited radius of my weather forecasts can be extrapolated to other parts of Cyprus. This is explained in detail at http://weather.bnellis.eu/notes/forecas ... ation.html
Incidentally, I am installing a third weather station, hopefully online in two or three weeks. I am already using it for lightning detection for distances up to 50 km, in theory, 35 km in practice. My aim is to improve the accuracy of my measurements by eliminating all mechanics in rain measurement, wind speed and wind direction: solid-state meteorology! I am anxious to see how it compares with conventional instruments!
