== What do the various wind speeds in Cumulus correspond to, with Fine Offset stations? ==
Fine Offset stations measure wind over 48-second intervals, divided into 24 2-second intervals. At the end of each 48-second period, they report the highest of those 24 values as 'Gust', and the average of those 24 values as 'Wind'. Cumulus, for various reasons, uses different terminology, and also has configuration settings which control how some of the wind values are displayed.
* The Fine Offset console 'Gust' value becomes Cumulus 'Latest'.
* The
Cumulus 'Average' can be calculated in 3 different ways:
* The Fine Offset console 'Wind' value becomes, with default settings, Cumulus 'Average'.
* All Fine Offset 'Gust' values read over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average''.
* All Fine Offset 'Wind' values read over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average'' and also set the next option ''Use 'speed' for avg calculation''.
Note if Cumulus is being re-started, the Fine Offset 'Gust' and 'Wind' values will initially only be available at the station's logging interval, so the last two options may only be averaging a couple of readings.
