Quantification of internal variability of the arctic summer atmosphere based on HIRHAM5 ensemble simulations
… of RCMs to realise different solutions of simulations that differ in their IC, but have the same lower and lateral boundary conditions (LBC), hence can be defined as the across-member spread between the ensemble members. For the investigation of the IV and the dynamical and diabatic …

Radiative Forcing and Climatic Impact of the Mount Pinatubo Volcanic Eruption
… 1992 and SON 1993 with the ENSO signals removed. Ensemble simulations were performed by using the ST-GCM to explore the responses of the atmosphere to the Pinatubo aerosol forcing and/or the observed SST anomalies. It is found that the ST-GCM simulates well the ENSO-induced DeltaTS over land. When …

Conceptualising and quantifying the nonlinear, chaotic climate: implications for climate model experimental design
… experiment consists of 11 different 50-member ensemble simulations with constant forcing, and three 50-member ensemble simulations under a climate change scenario with transient forcing. By analysing the output at global and regional scales, at least three distinct levels of IC influence are …

THE USE OF EXPANDED ENSEMBLE FOR THE PREDICTION OF WATER-ORGANIC SOLVENT PARTITION COEFFICIENTS OF SMALL DRUG-LIKE MOLECULES
… complex free energy landscapes. Expanded Ensemble (EE) is an advanced FEP-based technique that enhances sampling and parallelization by allowing the system to explore multiple thermodynamic ensembles during a single simulation. This method has shown considerable flexibility and accuracy in …

Fluid and Pressure Dynamics in Natural and Engineered Coastal Aquifer Systems
… in the context of injection-induced seismicity. Ensemble simulations reproducing the 2018 to 2022 pilot injections show that injection rates near 2 million gallons per day may generate pressure increases of approximately 40 kPa in the upper 200 m of the basement, although this response remains …

Internal and structural variability in global urban climate projections in CMIP6
… was assessed using the CESM-LE (large ensemble) simulations. Results show that there is an obvious structural variability of urban temperature change across CMIP models, ranging from 2-6 K, which aligns with that of background temperature change and increases with time. The structural …

Climate impact of aviation NOx̳ emissions : radiative forcing, temperature, and temporal heterogeneity
… mW/m² per Tg of NOx emissions). However, few simulations assess the surface air temperature (SAT) response, or conduct a large ensemble simulation with climate feedback in the cases where SAT is predicted. We aim to quantify the climate forcing and temperature response of aviation NOx …

Forced and Unforced Permafrost Changes in the Northern Hemisphere during 1901-2100
… indicating potential uncertainty in model simulations. To quantify these uncertainties, detection and attribution analyses were applied based on simulations made with CESM-LENS and CMIP6 models across the permafrost regions in the northern hemisphere. For a single model (CESM), the multiple …

Understanding the impacts of ENSO patterns on droughts over southern Africa using SPEEDY
… - LN4). In this study we analyzed multi-forcing ensemble simulations from SPEEDY (a general circulation model from the International Centre for Theoretical Physics) and used two drought indices (SPEI: Standardized Precipitation Evapotranspiration Index; SPI: Standardized Precipitation Index) to …

Statistical Modeling of the Effects of Process Variations on Silicon Photonics
… present in CMOS technology. Long and repetitive simulations are required to understand the effect of these variations, largely due to the lack of variation-aware models. This thesis explores methodologies for the development and application of process variation-aware compact models for silicon …

Efficient Algorithms And Optimizations For Scientific Computing On Many-Core Processors
… that has this serial behavior is the Monte Carlo simulations. Monte Carlo simulations have been used to simulate many problems in statistical physics and statistical mechanics that were not possible to simulate using Molecular Dynamics. While there are a fair number of well-known and recognized …

On intrinsic uncertainties in earth system modelling
… a bifurcation analysis with multi-parameter ensemble simulations. As a model-independent and therefore universal procedure, this method allows investigating the uncertainty referring to a bifurcation in a high dimensional parameter space in many other models. With the monsoon model the …
