How to enable windzone for a specific time interval

I am new to unity and just cannot find a way on how to enable a windzone for a specific time interval… (i have got the same problem for the lens flare effect and rain - but maybe i can figure out the rest on my own if i manage to do just one of them right)
I am grateful for every piece of advice!

You can use co-routines to do delayed events;

void EnableWindZone (float windZoneTime) {
	windzone.enabled = true;
	StartCoroutine (DisableWindZone (windZoneTime));


IEnumerator DisableWindZone (float windZoneTime) {

	yield return new WaitForSeconds(windZoneTime);
	windzone.enabled = false;
