The birth of numerical weather prediction [PDF]

open access: bronzeTellus A: Dynamic Meteorology and Oceanography, 1991
The paper describes the major events leading gradually to operational, numerical, short-range predictions for the large-scale atmospheric flow. The theoretical foundation starting with Rossby's studies of the linearized, barotropic equation and ending a decade and a half later with the general formulation of the quasi-geostrophic, baroclinic model by ...

Numerical Weather Prediction [PDF]

open access: bronzeAnnual Review of Fluid Mechanics, 1995
This review highlights a number of current areas of emphasis in research and operational numerical weather prediction. Detailed accounts of each area of activity are not presented; some key references are provided within each section for interested readers who may wish to explore further. The review outlines the types of weather prediction models where

Extension of the WRF-Chem volcanic emission preprocessor to integrate complex source terms and evaluation for different emission scenarios of the Grimsvötn 2011 eruption [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2020
Volcanic eruptions may generate volcanic ash and sulfur dioxide (SO2) plumes with strong temporal and vertical variations. When simulating these changing volcanic plumes and the afar dispersion of emissions, it is important to provide the best available ...
