Impact of Correction Target Selection on Long-Term Spectral Nudging in Luzon Strait and Its Adjacent Regions

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 ...

Effects of atmospheric sphericity on stratospheric chemistry and dynamics over Antarctica [PDF]

, 2005
Atmospheric sphericity is an important factor that must be considered in order to evaluate an accurate ozone loss rate in the polar stratosphere. The built-in plane-parallel radiative transfer scheme of a nudging chemical transport model (CTM) and an ...

Improving Regional Model Skills During Typhoon Events: A Case Study for Super Typhoon Lingling Over the Northwest Pacific Ocean

Frontiers in Marine Science, 2021
The ability of forecasting systems to simulate tropical cyclones is still insufficient, and currently, there is an increased interest in improving model performance for intense tropical cyclones. In this study, the impact of reducing surface drag at high

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.

How the meteorological spectral nudging impacts on aerosol radiation clouds interactions?

, 2023
Abstract. Meteorological and chemical modelling at the regional scale involve nudging to remain consistent with large-scale meteorology and meteo-chemical coupling to properly consider the interactions between aerosols, clouds and radiations. Both types of process can change meteorology, but not for the same reasons and not necessarily in the same way.

Internal Model Variability of Ensemble Simulations With a Regional Coupled Wave-Atmosphere Model GCOAST

Frontiers in Marine Science, 2020
Ensemble simulations are performed to quantify the internal variability of both regional atmospheric models and wave-atmosphere coupled model systems. Studies have shown that the internal variability in atmospheric models (e.g., wind or pressure fields ...

Anelastic sensitivity kernels with parsimonious storage for adjoint tomography and full waveform inversion [PDF]

, 2016
We introduce a technique to compute exact anelastic sensitivity kernels in the time domain using parsimonious disk storage. The method is based on a reordering of the time loop of time-domain forward/adjoint wave propagation solvers combined with the use
