Evaluation of Forecast Performance for Four Meteorological Models in Summer Over Northwestern China
Frontiers in Earth Science, 2021 At present, numerical models, which have been used for forecasting services in northwestern China, have not been extensively evaluated. We used national automatic ground station data from summer 2016 to test and assess the forecast performance of the ...

GenCast: Diffusion-based ensemble forecasting for medium-range weather [PDF]
arXiv, 2023 Weather forecasts are fundamentally uncertain, so predicting the range of probable weather scenarios is crucial for important decisions, from warning the public about hazardous weather, to planning renewable energy use. Here, we introduce GenCast, a probabilistic weather model with greater skill and speed than the top operational medium-range weather ...

Eos, Transactions American Geophysical Union, 1960 This report, like its predecessor of four years ago, concentrates on the prediction of atmospheric flow patterns by objective methods that are based on the laws of physics. Purely statistical‐empirical methods are not treated.

Weakening seasonality of Indo-Pacific warm pool size in a warming world since 1950
Environmental Research Letters, 2023 Seasonal variation of the Indo-Pacific warm pool (IPWP) plays an important role in oceanographic and climatological processes. While expansion of the IPWP under greenhouse warming has been widely discussed, the response of IPWP seasonality to climate ...

M-ENIAC: A machine learning recreation of the first successful numerical weather forecasts [PDF]
arXiv, 2023 In 1950 the first successful numerical weather forecast was obtained by solving the barotropic vorticity equation using the Electronic Numerical Integrator and Computer (ENIAC), which marked the beginning of the age of numerical weather prediction. Here, we ask the question of how these numerical forecasts would have turned out, if machine learning ...

Weather and Climate Extremes, 2023 Severe weather often occurs in the areas where different cold-warm and dry-wet air masses converge orthogonally. The orthogonal convergence of two-adjacent air parcels can be observed from planetary-scale to synoptic-scale and meso-scale circulations ...

The Compatibility between the Pangu Weather Forecasting Model and Meteorological Operational Data [PDF]
arXiv, 2023 Recently, multiple data-driven models based on machine learning for weather forecasting have emerged. These models are highly competitive in terms of accuracy compared to traditional numerical weather prediction (NWP) systems. In particular, the Pangu-Weather model, which is open source for non-commercial use, has been validated for its forecasting ...

A time-spectral approach to numerical weather prediction [PDF]
Computer Physics Communications, 2018 Finite difference methods are traditionally used for modelling the time domain in numerical weather prediction (NWP). Time-spectral solution is an attractive alternative for reasons of accuracy and efficiency and because time step limitations associated with causal, CFL-like critera are avoided.
