There is considerable overlap between entries for soleire and solerne in the dictionaries. The DMF defines soleire as a south wind and solerne as an east wind, though both entries also make reference to a wind from the other cardinal point. DEAF defines both as 'east wind'. No related entry is found in the OED, and the MED contains a single entry for solerne (defined as 'an east wind'), pointing to its etymon as both soleire and solerne. Latin subsolanus refers solely to an east wind according to the DMBLS.
