COLUMBIA, Mo. – Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.

Laurel McCoy, an atmospheric science graduate student at the MU School of Natural Resources, and Tony Lupo, professor and chair of atmospheric science in the College of Agriculture, Food and Natural Resources, surveyed 56,457 tornado-like events from 1950 to 2011. They found that when surface sea temperatures were warmer than average, the U.S. experienced 20.3 percent more tornados that were rated EF-2 to EF-5 on the Enhanced Fuijta (EF) scale. (The EF scale rates the strength of tornados based on the damage they cause. The scale has six category rankings from zero to five.) (more…)

Farmers should prepare for possible drought conditions through July

COLUMBIA, Mo. – Last summer, the Midwest experienced one of the hottest and driest summers on record. While a few rain showers have occurred across the Midwest the past few weeks, it appears that the region is in for another dry summer. A University of Missouri researcher says that an opposing weather pattern could bring more favorable weather conditions to the Midwest, but won’t be here until after this summer. (more…)

MU Expert Predicts Hot, Dry Summer for Midwest

COLUMBIA, Mo. – For nearly a year, the Midwest and southwest United States have experienced drought and warmer than normal conditions. A University of Missouri expert is predicting no relief, as he expects drought and hot conditions to continue this summer.

“I expect one of two scenarios to play out; the first is a continued La Nina climate pattern to affect our weather this summer,” said Tony Lupo, professor and chair of the Department of Atmospheric Science in the School of Natural Resources. “This will lead to a drought and above average heat throughout the Midwest from Texas to Iowa, where farmers with parched fields can least afford dry conditions. However, it is also possible that a new El Nino pattern could develop this fall. While I don’t see this happening, it would bring more favorable temperatures and precipitation patterns to the Midwest.” (more…)

*MU meteorologists say weather played a key role in union defeat*

COLUMBIA, Mo. — One hundred fifty years ago, two armies battled each other and the weather in Missouri’s first significant Civil War battle. While the battle’s course is familiar to historians, virtually no scientific data exists about the atmospheric conditions that influenced the fighting. In a project that blends history, sleuthing and modern weather analysis, Tony Lupo, professor and chair of the Department of Atmospheric Sciences at the University of Missouri, and Mike Madden, a meteorology student, have scientifically examined the heavy rains that hampered the union forces, eventually leading to a costly defeat.
