Vayu-Vata

Vāyu-Vāta is the Avestan name of a dual-natured Zoroastrian deity of the wind and of the atmosphere. The names are also used independently of one another, with 'Vāyu' occurring more frequently than 'Vāta', but even when used independently still representing the other aspect.
The entity is simultaneously angelic and demonic, that is, depending on the circumstances, either yazata - "worthy of worship" - or daeva, which in Zoroastrian tradition is a demon. Scripture frequently applies the epithet "good" when speaking of one or the other in a positive context.
In Zurvanism, Vāta-Vāyu represented two facets of the quaternary Zurvan. In this arrangement, Vāta-Vāyu represented "space" while the other two facets represent "time."
Vāyu-Vāta has Indo-Iranian roots and has the same name in historical Vedic religion.

In Sanskrit and Hinduism

Both the words Vāta and Vāyu have almost identical meanings in Sanskrit or Vedic traditions. Although there is no god representing Vāta, there is the god Vāyu representing air. The word Vāta is still used today in many Indian languages to denote atmosphere. Atmosphere in many Indian languages is called Vātāvaraṇa ; which is made of two words, Vāta and Āvaraṇa.
