METEOROLOGIST EXPLAINS HOW EL NIñO WILL IMPACT CROP YIELDS THIS SUMMER
Apr. 24, 2023
by Tyne Morgan, AgWeb.com
Drought was a major storyline for U.S. crop conditions last summer. Dry conditions spurred by La Nina weighed on corn yields across areas of the Corn Belt. As La Nina fades, and El Niño starts to make a return, meteorologists say the weather shift could also signal better crop production in 2023.
El Niño is the warm phase of the El Niño-Southern Oscillation, and it's associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific. While it can bring warm temperatures around the globe, agricultural meteorologist Eric Snodgrass says it also tends to bring favorable growing conditions for crops in the Midwest.
"We do have a great suite of models that we'd like to just combine and compare, and what's interesting about this particular year is they're all telling the same story. And that story is that we expect most of the Corn Belt to have decent summer thunderstorm activity, decent precipitation and a lack of long duration episodes of heat," says Snodgrass, the Principal Atmospheric Scientist with Nutrien Ag Solutions. "We always get short heat waves, but I'm talking about the long duration ones that can really go in there and destroy yields."
