Progressive Charlestown: Better weather predictions on the way?

AI
model shows promise to generate faster, more accurate weather forecasts
University
of Washington
Today s
weather forecasts come from some of the most powerful computers on Earth. The
huge machines churn through millions of calculations to solve equations to
predict temperature, wind, rainfall and other weather events.
A forecast s
combined need for speed and accuracy taxes even the most modern computers.
The
future could take a radically different approach. A collaboration between the
University of Washington and Microsoft Research shows how artificial
intelligence can analyze past weather patterns to predict future events, much
more efficiently and potentially someday more accurately than today s ....

AI could mine the past for faster, better weather forecasts -- GCN

Dec 21, 2020
Today’s weather forecasts come from some of the most powerful computers on Earth. The huge machines churn through millions of calculations to solve equations to predict temperature, wind, rainfall, and other weather events. A forecast’s combined need for speed and accuracy taxes even the most modern computers.
The newly developed global weather model bases its predictions on the past 40 years of weather data, rather than on detailed physics calculations.
The simple, data-based AI model can simulate a year’s weather around the globe much more quickly and almost as well as traditional weather models, by taking similar repeated steps from one forecast to the next, according to a paper in the ....

Scientists develop new land surface model including multiple processes and human activities

Human activities, such as urban planning, irrigation and agricultural fertilization, can affect terrestrial carbon, nitrogen and water cycle processes and aquatic ecosystems.
Some human activities lead to water stress, ecological environment damage, including groundwater lateral flow, and the movement of frost and thaw fronts. These changes in turn alter energy balance and water budget, and affect weather, climate and environment.
We need a new land surface model to describe these processes, said Prof. XIE Zhenghui from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences, a comprehensive land surface model can not only provide a platform for water-energy simulations, but also contribute to water resources management, environment protection and sustainable development. ....
