In climate change discussions, everybody talks about temperature. But weather is much more than that. There is at least rain and wind as directly experienced quality, and air pressure as measurable quantity. In the Netherlands, some observation stations have more than a century of daily data on these things. The data may be broken in the sense that equipment and location can have changed. To quote: “These time series are inhomogeneous because of station relocations and changes in observation techniques. As a result, these series are not suitable for trend analysis. For climate change studies we refer to the homogenized series of monthly temperatures of De Bilt link or the Central Netherlands Temperature link.” Since I am not looking at temperature but wind, I will keep to this station’s data.

Data

Data are from daily observations from KNMI. I have chosen station De Kooy. For those less familiar with Dutch geography, this is close to Den Helder, in the tip North West of Netherlands. This means pretty close to the North Sea, Wadden Sea and Lake IJssel. Wind should be relatively unhindered there. The data themselves are daily observations. For wind there are:
DDVEC Vector mean wind direction in degrees
(360=north, 90=east, 180=south, 270=west, 0=calm/variable)
FHVEC Vector mean windspeed (in 0.1 m/s)
FG Daily mean windspeed (in 0.1 m/s)
FHX Maximum hourly mean windspeed (in 0.1 m/s)
FHXH Hourly division in which FHX was measured
FHN …read more
