The Stormwater Report

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 […]

When Hurricane Harvey inundated eastern Texas late last August, the eye of the storm loitered over land for nearly a week rather than dispersing as it moved farther from the ocean, as most hurricanes do. The result was a stronger, more destructive storm, which dropped a record-breaking 127 cm (50 in.) of rain and directly […]

If trends toward warmer climates continue at the same pace that they have during the last few decades, the U.S. could see extreme rainfall events up to four times more frequently by the end of the 21st century, a new study by the National Center for Atmospheric Research (NCAR; Boulder, Colo.) finds. These storms could […]
