# Rounding too much

this isn’t my station, but I noticed at some other station that reported the windspeed in Beaufort that it appears to round it to integer values.

isn’t it normal seen the scale of beaufort

I’m not sure that in general practice the Beaufort Scale is reported with a decimal place? Each Beaufort number represents a range of wind speeds, so although you could report with a decimal number, this isn’t how it is generally used

aha, I understand now (I was about to write “aha, makes sense”, but actually it doesn’t )

however, even though the beaufort number is an integer, I can see plenty of references like 2.5 bft.
Also, even if the vertical scale of the graph has only integers, the graph itself could/should be nice and smooth, instead of stepwise.

apparently there is a formula for it:
“wind speeds on the 1946 Beaufort scale are based on the empirical formula: v = 0.836 B3/2 m/s, where v is the equivalent wind speed at 10 meters above the sea surface and B is the Beaufort scale number.”
So a smooth graph is certainly a possibility and would represent the accuracy of the device much better.
