An Investigation Of Climate Patterns On Earth-Like Planets Using The NASA GISS Global Climate Model II
… determine the capability of NASA's GISS GCM-II global climate model, the user-friendly EdGCM interface to the 3-D climate model code was evaluated by simulating global climate patterns that Earth-like planets may experience. The simulation scenarios involved different greenhouse gas emissions …

Simulating the characteristics of tropical cyclones over the South West Indian Ocean using an adaptive Stretched-Grid Global Climate Model
… the South West Indian Ocean (SWIO) have used Global Circulation Models (GCMs) with uniform grid. This study examines the capability of a GCM with adaptive grid stretching (CAM-EULAG, hereafter CEU) in simulating the characteristics of TCs over the SWIO. In the study, the CEU model is applied …

An investigation into the causes for the reduction in the variability of the El Niño-Southern Oscillation in the early Holocene in a global climate model
… a possible cause for this using output from a Global Climate Model forced by present day and early Holocene boundary conditions, and a simplified model that is known to simulate the El Nino-Southern Oscillation (ENSO).We devise a scheme to incorporate mean state data, into the background states …

Linearity of the Climate System Response to Antarctic Topography Change
A hierarchy of general circulation models is used to investigate the linearity of the response of the global climate system to changes in Antarctic topography. Models range in complexity from an atmospheric dry dynamical core to a slab-ocean global climate model with idealized West Antarctic ice …

Predicting Climate Change in Big Bend National Park, Texas
… downscaling to improve the resolution of global climate model predictions of temperature and precipitation over the next 100 years in Big Bend National Park, Texas. The method is an adaptation of climate prediction by model statistics. I use historical data from 12 weather stations and the …

Timescales of processes controlling water vapour entry to the stratosphere
… into the stratosphere in reanalysis and two global climate model configurations. This is done by applying the advection-condensation method and comparing alternative formulations. In the region of the atmosphere around 15–50 km altitude known as the stratosphere, water vapour is present in …

On the use of multivariate statistics to validate global climate models
… and compare those to the counterpart modes in a Global Climate Model (GCM). As a means to accomplish this, a multivariate statistical technique introduced for the first time to the atmospheric sciences, orthogonal Procrustes Target Analysis (PTA) was applied. A four dimensional analysis of the …

Understanding changes in precipitation with climate change over wet and dry land
… in precipitation over dry and wet land with climate change. Using global climate model output, the change in each term in the perturbation energy budget was calculated as a regional average over wet and dry tropical land. Increases in precipitation over wet and dry tropical land are primarily …

Future potential net primary production trends of contiguous United States rangelands
… 24% of the earth’s terrestrial vegetation. Climate change is predicted to affect many of the factors that influence the production of rangeland vegetation. Understanding future trends and patterns in net primary production (NPP) requires projected potential NPP to better understand how …

Attribution of the risk of extreme flood events to climate change in the context of changing land use and cover: case study of the shire river basin flood of 2015
… in draft format then and the adoption of the climate change management policy a year later. In the aftermath of the disaster, as with most extreme weather events elsewhere around the world, questions were asked as to whether climate change might have had a hand in the occurrence of such an …

The formal generation of models for scientific simulations
… for complex physical systems such as the climate system to be studied indirectly via computer simulations. Often, the equations that govern the underlying physical system are known but detailed or highresolution computer models of these equations (“governing models”) are not practical …

Attribution of the 2015-2016 hydrological drought in KwaZulu-Natal to anthropogenic climate change
… on the environment, society and the economy. Climate change is predicted to exacerbate extreme events such as droughts that would adversely affect already vulnerable regions such as KZN. The main aim of this study is to implement the attribution procedure, to determine if climate change has …

Modeling Hourly Storm Surges using Deep Learning Techniques
… the most devastating coastal hazards. Accurate modeling of storm surges is essential for predicting and mitigating these impacts. Traditional approaches model surges at individual tide gauges and often focus on daily time scales, leading to data redundancy and limiting their ability to capture …

Climate extremes over the Mid-Atlantic states: a regional approach
… can be predicted based on the past. However, as global temperatures rise, established climate ranges may no longer be applicable, as historic records for extremes such as heat waves and floods may no longer accurately predict the changing future climate. To assess extremes (present-day and …

Integrating urban heat island influences into statistically downscaled climate projections in the Truckee Meadows, Nevada
… projections for the Truckee Meadows produced by global climate model data under three IPCC emissions scenarios (A1b, A2 and B2) for the future period 2041-2060 were examined. Results indicated that a bias correction and constructed analogs method with an additional bias correction step that …

Climate change and hazardous convective weather in the United States: Insights from high-resolution dynamical downscaling
<p>Global climate model (GCM) projections increasingly suggest that large-scale environmental conditions favorable for hazardous convective weather (HCW) may increase in frequency in the future due to anthropogenic climate change. However, this storm environment-based approach is undoubtedly …

Reversibility of Sea Ice and Climate under Global Change
… sea ice area and volume. Using an autoregressive model of sea ice and numerical simulation with a global dynamic-thermodynamic sea ice model that traces first-year and multiyear, we show that the sea ice mean state, variability, and sensitivity to forcing may be related to sea ice age. Ice age …
