Using machine learning to predict a ground frost

Machine learning can be used to forecast when a geographical region might have a ground frost, according to new work published in the International Journal of Reasoning-based Intelligent Systems. Weather forecasting for a ...

Scientists use holography to peer into clouds

Watching clouds go by, swirls of white puff up and melt away. The changes mirror mixing within the clouds as drier air mingles with water-saturated air.

Cold, dry planets could have a lot of hurricanes

Nearly every atmospheric science textbook ever written will say that hurricanes are an inherently wet phenomenon—they use warm, moist air for fuel. But according to new simulations, the storms can also form in very cold, ...

Farmers use tech to squeeze every drop from Colorado River

A drone soared over a blazing hot cornfield in northeastern Colorado on a recent morning, snapping images with an infrared camera to help researchers decide how much water they would give the crops the next day.

Shuffling bubbles reveal how liquid foams evolve

Foams are found everywhere, in soaps and detergents, meringues, beer foam, cosmetics and insulation for clothing and building. The application of foams tends to take advantage of their unique structure, which is why understanding ...

Collaborative unmanned systems extinguish fire in demonstration

Lockheed Martin demonstrated its ability to integrate unmanned aircraft system (UAS) operations into the National Airspace System (NAS) using its prototype UAS Traffic Management (UTM) capabilities. During the demonstration ...

Probing water's skin

From the wind-whipped surface of the open ocean, to trillions of tiny water drops in clouds, the air-water interface—water's skin— is the site for crucial natural processes, including ocean-atmosphere exchange and cloud ...
