Difference in Wind speeds from Cumulus and Heavy Weather

Post by Brian Ludwig »

I seem to be getting large differences in the wind gust from my LaCrosse 2350 station - today I has a reading of 18.1MPH with Heavy Weather but 9.1 with Cumulus. I suspect that Cumulus is correct but would like to know why there is a difference.
Thanks
Brian

You're presumably not running them at the same time, so they don't have access to the same data. Data from the station's logger is just a snapshot of the readings at that time.

Hi
The data in the history file only shows the data at the interval you set in the HeavyWeather software (ie only at set intervals) which does not mean they are not correct.
