MU Researchers Try to Better Predict Storms that Produce Deadly Flash Flooding

Weather phenomenon triggers intense rainfall that leads to flash floods

COLUMBIA, Mo. – According to the National Weather Service, more than 125 people die from flash floods every year. Flash floods often arise from a weather phenomenon known as an “elevated convection,” which causes intense thunderstorms that lead to flash flooding. However, scientists do not have a strong understanding of what causes these elevated storms. A team of researchers at the University of Missouri will deploy to eastern Kansas and western Missouri to study this phenomenon throughout the spring. (more…)

Warmer temperatures push malaria to higher elevations

ANN ARBOR — Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year.

Now, University of Michigan ecologists and their colleagues are reporting the first hard evidence that malaria does—as had long been predicted—creep to higher elevations during warmer years and back down to lower altitudes when temperatures cool. (more…)

Movement of marine life follows speed and direction of climate change

Scientists expect climate change and warmer oceans to push the fish that people rely on for food and income into new territory. Predictions of where and when species will relocate, however, are based on broad expectations about how animals will move and have often not played out in nature. New research based at Princeton University shows that the trick to more precise forecasts is to follow local temperature changes.

The researchers report in the journal Science the first evidence that sea creatures consistently keep pace with “climate velocity,” or the speed and direction in which changes such as ocean temperature move. They compiled 43 years of data related to the movement of 128 million animals from 360 species living around North America, including commercial staples such as lobster, shrimp and cod. They found that 70 percent of shifts in animals’ depth and 74 percent of changes in latitude correlated with regional-scale fluctuations in ocean temperature. (more…)
