Better hurricane forecasts from use of infrared satellite measurements of cloudy skies
Weather forecast models have long struggled to integrate satellite observations of infrared radiation in cloudy regions of the sky. But in recent years, some satellite data providers have developed new techniques to integrate such data. A group of re.....»»
Scientists use drones to track white sharks along California beaches
The forecast at the beach today is cloudy, with a chance of sharks. At least, that's the forecast that researchers at UC Santa Barbara would like to be able to provide. They're leading a project to predict when and where great white sharks show up ne.....»»
Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions
Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disa.....»»
