Ali,
I will preface this with saying that calculating a yearly rolling average can be slow. It requires looking at a lot of data.
You can create the condition you are looking for with the formula tool. The following syntax will generate a condition with a capsule everyday extending 1 year. 

periods(1year,1day)

See screen shot below for formula details.


Lastly you can calculate the rolling average with the signal from condition tool.  See screen shot below for how to set up a yearly rolling average.


Hope this helps,
Teddy

The simplest method for filtering a signal to only view samples with values above a threshold is to use the .remove() function coupled with a numeric value comparison in formula. 
Example formula:

 
Resulting signal:

 
Another method is to use the .remove() function in combination with a condition. This gives some added flexibility to further customize the condition you are removing data during vs just removing data under a certain threshold.
Example using .grow() to increase the duration of the condition that data is being removed during:

 
Resulting signal: 


Depending on interpolation of the data, you could also consider using the .within() function. Check out the following post that explains the differences of working with .remove() and .within():

Writing it like the following is only supported for scalars:
max($a,$b,$c,$d) 
If you want to use signals you will need to write it this. 
$signalA.max($signalB).max($signalC)....
