'East Wind' in the Bible

Then behold, seven ears [of grain], thin and dried up by the east wind, sprouted after them.

and lo, seven [other] ears, withered, thin, and scorched by the east wind, sprouted after them;

The seven thin and ugly cows that came up after them are seven years; and also the seven thin ears, dried up and scorched by the east wind, they are seven years of famine and hunger.
