Differences between downscaling with spectral and grid nudging using WRF [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Dynamical downscaling has been extensively used to study regional climate forced by large-scale global climate models. During the downscaling process, however, the simulation of regional climate models (RCMs) tends to drift away from the driving fields ...

A spectral nudging method for the ACCESS1.3 atmospheric model [PDF]

open access: yesGeoscientific Model Development, 2015
A convolution-based method of spectral nudging of atmospheric fields is developed in the Australian Community Climate and Earth Systems Simulator (ACCESS) version 1.3 which uses the UK Met Office Unified Model version ...

Impacts of Spectral Nudging Parameters on Dynamical Downscaling in Summer over Mainland China [PDF]

open access: yesFrontiers in Earth Science, 2020
Spectral nudging is an important method of improving the effectiveness of dynamical downscaling in the Weather Research and Forecasting model (WRF). However, spectral nudging is sensitive to nudging parameters, and most related research has typically ...

Sensitivity Evaluation of Spectral Nudging Schemes in Historical Dynamical Downscaling for South Asia [PDF]

open access: yesAdvances in Meteorology, 2017
Sensitivity experiments testing two scale-selective bias correction (SSBC) methods have been carried out to identify an optimal spectral nudging scheme for historical dynamically downscaled simulations of South Asia, using the coordinated regional ...

Comparison of Analysis and Spectral Nudging Techniques for Dynamical Downscaling with the WRF Model over China [PDF]

open access: yesAdvances in Meteorology, 2016
To overcome the problem that the horizontal resolution of global climate models may be too low to resolve features which are important at the regional or local scales, dynamical downscaling has been extensively used.

Impacts of using spectral nudging on regional climate model RCA4 simulations of the Arctic [PDF]

open access: yesGeoscientific Model Development, 2013
The performance of the Rossby Centre regional climate model RCA4 is investigated for the Arctic CORDEX (COordinated Regional climate Downscaling EXperiment) region, with an emphasis on its suitability to be coupled to a regional ocean and sea ice model ...

Impact of Wave Number Choice in Spectral Nudging Applications During a South Atlantic Convergence Zone Event [PDF]

open access: yesFrontiers in Earth Science, 2018
Several studies showed the advantages of using nudging techniques to enforce the evolution of a numerical model to approximate large-scale features to a reference.

Large-scale secondary circulations in a limited area model – the impact of lateral boundaries and resolution [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2018
Within their domain, regional climate and weather forecasting models deviate from the driving data. Small-scale deviations are a desired effect of adding regional details.

A ten-year (2012–2021) fine-resolution (1 km, hourly) precipitation dataset over southeastern Tibetan Plateau [PDF]

open access: yesScientific Data
Intense sub-daily precipitation on the Tibetan Plateau (TP) can trigger a cascade of natural hazards (flash floods, debris flows, etc.), causing significant environmental impacts. Current precipitation products for the TP often lack sufficient spatial or

High resolution Tibetan Plateau regional reanalysis 1961-present [PDF]

open access: yesScientific Data
With the rapid global warming in recent decades, the Tibetan Plateau (TP) has suffered severe impacts, such as glacier retreat, glacial lake expansion, and permafrost degradation, which threaten the lives and properties of the local and downstream ...
