The Impact of Grid and Spectral Nudging on the Variance of the Near-Surface Wind Speed [PDF]
Journal of Applied Meteorology and Climatology, 2015 AbstractGrid and spectral nudging are effective ways of preventing drift from large-scale weather patterns in regional climate models. However, the effect of nudging on the wind speed variance is unclear. In this study, the impact of grid and spectral nudging on near-surface and upper boundary layer wind variance in the Weather Research and Forecasting

A Methodology for Attributing the Role of Climate Change in Extreme Events: A Global Spectrally Nudged Storyline [PDF]
Natural Hazards and Earth System Sciences, 2020 Abstract. Extreme weather events are associated with unusual dynamical conditions, yet the signal-to-noise ratio of the dynamical aspects of climate change that are relevant to extremes appears to be small, and the nature of the change can be highly uncertain.

Influence of sea salt aerosols on the development of Mediterranean tropical-like cyclones [PDF]
Atmospheric Chemistry and Physics, 2021 Medicanes are mesoscale tropical-like cyclones that develop in the Mediterranean basin and represent a great hazard for the coastal population. The skill to accurately simulate them is of utmost importance to prevent economical and personal damage ...

Sensitivity of simulating Typhoon Haiyan (2013) using WRF: the role of cumulus convection, surface flux parameterizations, spectral nudging, and initial and boundary conditions [PDF]
Natural Hazards and Earth System Sciences, 2022 Typhoon (TY) Haiyan was one of the most intense and highly destructive tropical cyclones (TCs) to affect the Philippines. As such, it is regarded as a baseline for extreme TC hazards.

Journal of Marine Science and Engineering, 2023 Previous studies have pointed out that spectral nudging is still insufficient in improving the long-term simulation ability of numerical models. In response to this problem, this study started with the Luzon Strait and its adjacent areas and discussed ...

Spectral nudging in a spectral regional climate model
Tellus A: Dynamic Meteorology and Oceanography, 2008 Spectral nudging, a dynamic downscaling method, has been used as a suitable approach to force a regional model to adopt prescribed large-scales over the entire domain, not just at the lateral boundaries, while developing realistic detailed regional features consistent with the large-scales.

The Impact of Spectral Nudging on Cloud Simulation with a Regional Atmospheric Model [PDF]
Journal of Atmospheric and Oceanic Technology, 2006 Abstract The impact of spectral nudging on cloud simulation with a regional atmospheric model was examined. Simulated cloudiness of the Regional Model (REMO) and the Spectrally Nudged REMO (SN-REMO) were intercompared and evaluated with satellite-derived cloudiness from the International Satellite Cloud Climatology Project (ISCCP).
