An incremental analysis update in the framework of the four‐dimensional variational data assimilation: Description and preliminary tests in the operational China Meteorological Administration Global Forecast System Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2024-03-15 Liwen Wang, Yongzhu Liu, Daosheng Xu, Lin Zhang, Jeremy Cheuk‐Hin Leung, Haorui Li, Jiandong Gong, Banglin Zhang
Initialization and the spin‐up effect are critical to model performance in the four‐dimensional variational data assimilation (4DVar) system. The incremental analysis update (IAU) technique is able to combat these problems. This study introduces the IAU technique into the 4DVar framework (IAU‐4DVar) of the operational China Meteorological Administration Global Forecast System (CMA‐GFS) and evaluates

A quadratic conservation algorithm for non‐hydrostatic models Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2024-03-06 Shifeng Hao, Xiaopeng Cui
We propose a quadratic conservation algorithm for non‐hydrostatic models, focusing on energy conservation and consistency. To ensure that the discrete potential and continuity equations are equivalent and to achieve conservation of mass and momentum transport, we introduce a potential reference height into the discrete potential equation. The time integration scheme is based on an explicit fourth‐order

Impact of Saharan dust outbreaks on short‐range weather forecast errors in Europe Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2024-03-06 Kilian Hermes, Julian Quinting, Christian M. Grams, Corinna Hoose, Gholam Ali Hoshyaripour
Mineral dust, the most abundant atmospheric aerosol by mass, interacts with radiation directly and alters cloud properties indirectly. Many operational numerical weather prediction models account for aerosol direct effects by using climatological mean concentrations and neglect indirect effects. This simplification may lead to shortcomings in model forecasts during outbreaks of Saharan dust towards

The moist halo region around shallow cumulus clouds in large eddy simulations Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2024-02-27 Jian‐Feng Gu, Robert Stephen Plant, Christopher E. Holloway, Peter A. Clark
In this study, the moist buffering halo region of shallow maritime cumulus clouds is systematically investigated using large eddy simulations with various grid resolutions and numerical choices. Autocorrelation analyses of cloud liquid water and relative humidity suggest a converged size of 200–300 m for moist patches outside clouds when the model resolution is below 50 m, but may overestimate this

Update to aircraft observations and reanalysis depictions of trends in the North Atlantic winter jet stream wind speeds and turbulence Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2024-02-20 Joel Tenenbaum, Paul D. Williams
Three more Northern Hemisphere winters (2021–2023) of European Centre for Medium-range Weather Forecasts Reanalysis v5 (ERA5) data and the North Atlantic Oscillation series have become available. These winters can be used to extend the 2002–2020 wind-speed time series in our article (Tenenbaum et al., 2022; figs 2 and 4). When we add these new years to the previous results, the statistical significance

Deterministic and Stochastic Tendency Adjustments Derived from Data Assimilation and Nudging Q. J. R. Meteorol. Soc. (IF 8.9) Pub Date : 2023-12-27 William E. Chapman, Judith Berner
We develop and compare model-error representation schemes derived from data assimilation increments and nudging tendencies in multi-decadal simulations of the community atmosphere model, version 6. Each scheme applies a bias correction during simulation run-time to the zonal and meridional winds. We quantify to which extent such online adjustment schemes improve the model climatology and variability
