Less snowpack may mean greater floods in western U.S.

In several mountainous and high-latitude regions, one of the major consequences of climate change means that more winter precipitation falls as rain than as snow. The downtick in snowfall and uptick in rainfall is particularly impactful in much of the western U.S., where melting winter mountain snowpack makes a crucial difference for water supplies in […]

Facial recognition AI sizes up hailstorms before they happen

Predicting the size and expected runoff volumes from hailstorms is notoriously difficult, according to researchers with the U.S. National Center for Atmospheric Research (NCAR). Because cloud systems that produce rain often have different features than those that produce hail, conventional prediction methods often fail to yield accurate forecasts. NCAR researchers investigating the challenge of hailstorm […]

USDA studies plant nursery runoff remediation

What’s the difference between a crop field and a large commercial plant nursery? As it turns out, very little — at least in terms of runoff generation. Although nurseries generally grow tree crops and ornamental plants in pots rather than fields, both field crops and nursery planters contribute to water pollution when rain washes excess […]
