Modeling Interactions Between Cities and Climate Across Scales

Cities now house more than half of humanity and consume the majority of energy resources. Urban areas alter climate and atmospheric chemistry in ways that can be important at regional to global scales. However, processes influencing climate, as well as the impacts of climate extremes, are often important at the scale of individual […]

Advances in modeling and sensors can help farmers and insurers manage risk

Modeling Earth’s Ever-Shifting Magnetism – Eos

On a day-to-day basis, most of us probably take for granted how much Earth’s deep inner workings affect some of modern life’s conveniences, like the relative ease with which we find our way from place to place by plane, boat, or automobile or on foot. Roughly 2,900 kilometers below the planet’s surface, convection […]

Modeling the Creation of Cratons, Earth’s Secret Keepers

The continents, the solid blocks of land beneath our feet, weren’t always as strong as they’ve come to be. Now, scientists from Monash University in Australia have devised a new mechanism to explain how the roots of the continents—cratons—came to be. Using numerical models to simulate the conditions of Archean era Earth, the […]

Modeling can help balance economy, health during pandemic

Credit: CC0 Public Domain This summer, when bars and restaurants and stores began to reopen across the United States, people headed out despite the continuing threat of COVID-19. As a result, many areas, including the St. Louis region, saw increases in cases in July. Using mathematical modeling, new interdisciplinary research from the lab of Arye […]

New research analyzes modeling techniques for carbon capture technology

Credit: CC0 Public Domain In the transition toward clean, renewable energy, there will still be a need for conventional power sources, like coal and natural gas, to ensure steady power to the grid. Researchers across the world are using unique materials and methods that will make those conventional power sources cleaner through carbon capture technology. […]

Research leads to better modeling of hypersonic flow — ScienceDaily

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth’s atmosphere, it reaches hypersonic speeds — more than five times the speed of sound — and generates temperatures […]
