Energy and Numerical Weather Prediction [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 1960 Since the study of energy transformations and the numerical integration of simplifiied equations are sometimes used as alternative approaches to the same physical problem, it is often desirable that the simplified equations conserve total energy under reversible adiabatic processes.

Mean radiant temperature from global-scale numerical weather prediction models. [PDF]
Int J Biometeorol, 2020 In human biometeorology, the estimation of mean radiant temperature (MRT) is generally considered challenging. This work presents a general framework to compute the MRT at the global scale for a human subject placed in an outdoor environment and ...

The birth of numerical weather prediction [PDF]
Tellus 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]
Annual 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

A Time-spectral Approach to Numerical Weather Prediction [PDF]
Computer Physics Communications, 2017 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 ...

Mixed finite elements for numerical weather prediction [PDF]
Journal of Computational Physics, 2012 We show how two-dimensional mixed finite element methods that satisfy the conditions of finite element exterior calculus can be used for the horizontal discretisation of dynamical cores for numerical weather prediction on pseudo-uniform grids.

Numerical Weather Prediction in New Zealand [PDF]
Monthly Weather Review, 1977 Abstract The main problem in weather forecasting over New Zealand and the Southern Oceans is the lack of sufficient data for good analyses, especially at upper levels. Numerical weather prediction also suffers from this problem, but it can to some degree be alleviated by producing several prognoses from reasonable alternative analyses to alert the ...

On the impact of humidity observations in numerical weather prediction [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 2005 The impact of humidity observations on forecast skill is explored by producing a series of global forecasts using initial data derived from the ERA-40 reanalyses system, in which all humidity data have been removed during the data assimilation. The new forecasts have been compared with the original ERA-40 analyses and forecasts made from them.

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]
Natural 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 ...
