Reply: Corn “Sweat”
For those who’re not from the Midwestern United States, there’s an excellent probability that you just suppose we’re pulling your leg, however we guarantee you we’re not. Throughout the peak of summer time warmth within the Midwest, a big contributor to the sweltering humidity is corn. Corn, nicely, sweating.
When it will get actually sizzling outdoors, corn loses moisture by way of evapotranspiration—water discharge by way of tiny pores within the leaves. It’s just about the plant model of sweating. Whereas all crops lose moisture within the warmth (although crops tailored to arid climates lose little or no), corn readily releases moisture when burdened by warmth.
This issue, mixed with the sheer quantity of corn within the Midwest—there are 96 million acres of corn planted within the U.S. with the vast majority of it within the Midwest—truly raises the ambient humidity considerably. The phenomenon known as “corn sweat” and it may well make days in July and August depressing in corn dense areas of the Midwest, highlighted within the USDA corn manufacturing map seen right here.
