Grounded aircraft could make weather forecasts less reliable

Thanks to travel restrictions and plummeting customer demand, the number of flights in the first week of April 2020 was down 61% compared with the same period in 2019. The pandemic has emptied the skies of aircraft, but it's ...

Ocean acidification prediction now possible years in advance

CU Boulder researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected ...

NASA study adds a pinch of salt to El Niño models

When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity—or saltiness—data significantly improves model accuracy, according to a new NASA study.

A new method to improve tropical cyclone intensity forecasts

In numerical weather forecasting research, how to improve short-term forecasts of tropical cyclone intensity is a challenging problem that has long plagued meteorologists and operational forecasters, despite that meteorologists ...

NASA soil data joins the Air Force

Getting stuck on a muddy road is a hassle for anyone, but for the U.S. Army it could be far more serious—a matter of life and death in some parts of the world. That's one of the reasons the U.S. Air Force HQ 557th Weather ...

GPS helping provide more precise precipitation predictions

Scientists are using GPS signals to measure air moisture for better weather forecasting. The method is now being incorporated into the Bureau of Meteorology's weather forecast models following successful tests over Australia, ...

Dorian strikes Bahamas as dangerous Category 5 storm

Hurricane Dorian struck the northern Bahamas on Sunday as a catastrophic Category 5 storm, its 185 mph winds ripping off roofs and tearing down power lines as hundreds hunkered in schools, churches and other shelters.
