R help - Aug 2024 - [FORGED] Fitting arima Models with Exogenous Variables

good morning 

I am working on my project and I am fitting an SARIMAX model on my data 
I have a seasonal thime sereis O3 levels 
With 3 variables temperature, humidity and wind speed..

The O3, temperature and humidity shows a sesonal behavior, however, wind speed
is stationary

When I fit the model using Arima() in R.. is it correct to include the wind
speed? Since it?s stationary so the model will take the seasonal difference

Can you help me ?
Thanks
