The model ARIMA+GARCH writing as this form with the rugarch package in R:

```
spec=ugarchspec(variance.model=list(garchOrder=c(1,1)),
                            mean.model=list(armaOrder=c(2,1)))

```

**My Question:** How to write in case if the model SARIMA+GARCH in R?

Where SARIMA model: 

`Model <- Arima(data,order=c(2,1,2),seasonal=list(order=c(1,0,0),12))`
