The wind is periphrased as son of Fornjótr, brother of Ægir and of fire, breaker of trees and wolf of the forest. One verse by Sveinn.
Hvernig skal kenna vind? Svá, at kalla hann son Fornjóts, bróður Ægis ok elds, brjót viðar, skaði ok bani eða hundr eð vargr viðar eða segls eða seglreiða. Svá sagði Sveinn í Norðrsetudrápu:
How shall the wind be periphrased? Thus: by calling it son of Fornjótr, brother of Ægir and of fire, breaker of trees, harm and bane — or hound or wolf — of trees or sail or rigging. Thus said Sveinn in the Norðrsetudrápa:
Skaldic quotations

The ugly sons of Fornjótr [the winds] first began to bluster.
