Kemudian tampak tujuh bulir gandum lain yang kurus dan layu diembus angin timur, tumbuh menyusul bulir-bulir itu.
Rashi
ושדופת PARCHED old French hales, (i.e. burnt up by the east wind) — But the Targum renders it by שקיפן קדום beaten upon by the east wind (and so burst open). This Aramaic word שקיפן is of the same root as משקוף a lintel, which is beaten continually by the door which knocks against it.
Chizkuni
ושדופות קדים, “and parched by the east wind;” the wind coming from the eastern regions is known as kadim. It had been heated by the sun from which it blew in, as the sun there had risen earlier. This is alluded to in the expression קדמה מזרחה, (Exodus 27,13). The reason why the “west” in Hebrew is called: מערב, is that when the sun sets in the west it is evening.
Ramban
SPRUNG UP AFTER THEM. Not that he saw them springing up —[although the word tzomchoth is actually in the present tense] — for he saw ripe ears of corn. But the verse is to be interpreted as if it said “they sprang up,” [i.e., tzamchu, which is in the past tense], suggesting that no sooner did he see the full ears than he immediately saw the thin ones coming up after them, for he saw the sign of immediacy in all facets of the dream.
