Impact of Spectral Nudging on Real‐Time Tropical Cyclone Forecast
Journal of Geophysical Research D: Atmospheres, 2018 AbstractRegional models often face a chronic problem caused by inconsistencies between simulated model fields and large‐scale forcing data, which could limit predictability of regional models. Spectral nudging is a technique which can ameliorate this issue by providing large‐scale forcing in the regional model interior.

Effects of Spectral Nudging in WRF on Arctic Temperature and Precipitation Simulations
Journal of Climate, 2013 Abstract Spectral (interior) nudging is a way of constraining a model to be more consistent with observed behavior. However, such control over model behavior raises concerns over how much nudging may affect unforced variability and extremes.

Effects of Spectral Nudging on Oceanic States in a Coarse-Resolution Model
Atmosphere - Ocean, 2015ABSTRACTA 1-degree global model is used to investigate the skill of spectral nudging at coarse resolution by performing two numerical experiments, one with spectral nudging and the other without. In the spectral nudging experiment, the model temperature and salinity are nudged to an observed climatological monthly-mean field.

Simulation of Mixed Layer Depth in the Northeast Pacific Utilizing Spectral Nudging
Journal of Physical Oceanography, 2011 Abstract A numerical model, the Parallel Ocean Program (POP), is used to run a 46-yr simulation of the North Pacific Ocean beginning in January 1960. The model has 0.25° horizontal resolution and 28 vertical levels, and it employs spectral nudging, which, unlike standard nudging, nudges only specific frequency and wavenumber bands.

Theoretical and Applied Climatology, 2021 This study assesses the performance of the Weather Research and Forecasting (WRF) model in simulating the Arabian Peninsula summer climate for the period 2001–2016. The European Centre for Medium range Weather Forecast (ECMWF) reanalysis is downscaled using WRF without (CTRL) and with the Spectral Nudging (SPN) method.

Effects of spectral nudging on the 2010 East Asia summer monsoon using WRF model
Chinese Journal of Oceanology and Limnology, 2012The performance of spectral nudging in an investigation of the 2010 East Asia summer monsoon was assessed using the Weather Research and Forecasting (WRF) model, forced by 1-degree NCEP Global Final Analysis (FNL). Two pairs of experiments were made, spectral nudging (SP) and non-spectral nudging (NOSP), with five members in each group.

Journal of Geophysical Research, 2011 This study examines simulated typhoon sensitivities to spectral nudging (SN) to investigate the effects on values added by regional climate models, which are not properly resolved by low-resolution global models.
