The air is called ginnungagap, middle-world, bird-world; the weather hregg, byrr, vindr, etc. An Alvíssmál-like verse gives the wind's names in the different worlds (vindr among men, 'neigher' among the gods, 'roarer' in Hel).
Hver eru heiti lofts ok veðranna? Loft heitir ginnungagap ok meðalheimr, foglheimr, veðrheimr. Veðr heitir hregg, byrr, glygg, hret, gjósta, vindr. Svá segir í Alsvinnsmálum:
What are the names of the air and the winds? The air is called ginnungagap and middle-world (meðalheimr), bird-world (foglheimr), weather-world (veðrheimr). Weather is called hregg, byrr, glygg, hret, gjósta, vindr. Thus it says in the Alsvinnsmál:
Veðr heitir ok gustr.
Weather is also called gustr [gust].
Skaldic quotations
Alsvinnsmál (vindens namn i världarna)
Vindr heitir með mönnum, en vönsuðr með goðum, kalla gneggjuð ginnregin, æpi jötnar, en alfar gnýfara, heitir í helju hlömmuðr.
It is called wind (vindr) among men, and 'waverer' (vönsuðr) among the gods; the mighty powers call it 'neigher' (gneggjuðr), the giants 'howler' (æpir), and the elves 'din-farer' (gnýfari); in Hel it is called 'roarer' (hlömmuðr).
