Many are calling this dry spell in July that followed the wettest spring on record a “flash drought.” Iowa State University extension climatologist, Elwyn Taylor, is not one of them.
Taylor says drought is defined by law as dryness in any county that cuts crop yields by 10-percent. So unless that happens for Iowa’s corn, Taylor isn’t using the word drought.
As for the flash drought, Taylor says he understands why the term is being used.
Taylor says slow moving polar weather patterns are lengthening the dry period just like they caused persistent spring rains.
