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).

Comparison of GCM- and RCM-simulated precipitation following stochastic postprocessing [PDF]

, 2014
In order to assess to what extent regional climate models (RCMs) yield better representations of climatic states than general circulation models (GCMs), the output of each is usually directly compared with observations. RCM output is often bias corrected,

Does Spectral Nudging Have an Effect on Dynamical Downscaling Applied in Small Regional Model Domains? [PDF]

Monthly Weather Review, 2017
Spectral nudging is a method that was developed to constrain regional climate models so that they reproduce the development of the large-scale atmospheric state, while permitting the formation of regional-scale details as conditioned by the large scales.

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.

Complete synchronization of chaotic atmospheric models by connecting only a subset of state space [PDF]

, 2012
Connected chaotic systems can, under some circumstances, synchronize their states with an exchange of matter and energy between the systems. This is the case for toy models like the Lorenz 63, and more complex models.

Climate Change Attribution of Extreme Weather Events using Spectrally Nudged Event Storylines

, 2022
Heatwaves, droughts, floods, storms and other types of extreme weather events cause significant human suffering as well as material and economic damages. Discerning how climate change is influencing different extremes is a prerequisite to understand what we may expect in the future and how we can reduce loss of life and damage.

The vertical distribution of ozone instantaneous radiative forcing from satellite and chemistry climate models [PDF]

, 2011
We evaluate the instantaneous radiative forcing (IRF) of tropospheric ozone predicted by four state-of-the-art global chemistry climate models (AM2-Chem, CAM-Chem, ECHAM5-MOZ, and GISS-PUCCINI) against ozone distribution observed from the NASA ...
