(Funding studies attributing extreme weather
using regional climate models which show no skill at decadal prediction is currently a waste of time.)
Downscaling
with regional climate models offers improvements in the mean rainfall climatology, and shows some ability to correct for poor modelled relationships between rainfall and zonal winds along the east coast of Australia.
As such, the 2003 heatwave resembles simulations
by regional climate models of summer temperatures in the latter part of the 21st century under the A2 scenario (Beniston, 2004).
His current interests include: use of climate projections at the community level, impacts of climate change on biodiversity, and analysis of results
from regional climate models and other forms of downscaling.
Vahmani and Jones used a high - resolution
regional climate model for their analysis; Vahmani then added a component to the model to account for irrigation water.

regional climate model trends; Environmental Research Letters, 8, 1, 014055, doi: 10.1088 / 1748-9326/8 / 1 / 014055.
Our experimental setup involves using the
Canadian regional climate model (CRCM) outputs as pseudo-observations to estimate model performance in the context of future climate projections by replacing historical and future observations with model simulations from the CRCM, nested within the domain of the Canadian global climate model (CGCM).
Instead, researchers often use regional - scale climate models to characterize real - world weather events, but different representations of physical, chemical, and other processes between global and
regional climate models produce inconsistent information about the atmosphere.
Define research needs for the development of a next
generation regional climate model based on the Weather Research and Forecasting model (WRF) and Community Climate System Model (CCSM)
Last week, there was a CORDEX workshop on
regional climate modelling at International Centre for Theoretical Physics (ICTP), near Trieste, Italy.
Since 500 million people across the world live along the coastal delta, understanding of the Ganga - Brahmaputra - Meghna (GBM) delta will be crucial in developing
such regional climate models in the next project that looks at India Sunderbans and Mahanadi basin, Bangladesh Sunderbans, Egypt Nile delta and Ghana Volta delta,» Nicholls told TOI.
The Hurricane Prediction System forecasts the movement and intensity of hurricanes, while global and
regional climate models simulate the influence on hurricane activity of various atmospheric and oceanic processes, including climate change and variability.
Simulations by
regional climate models show good agreement with observations in the seasonal and spatial variability of the joint distribution, especially when an ensemble of simulations was used.
The researchers analyzed Atlanta, Philadelphia and Phoenix using global and
regional climate models under a business - as - usual scenario and under an aggressive heat management program.
The analysis uses methods that have already been peer - reviewed, including examining the change in occurrence of such extreme rains in the historical record and in climate models, as well as using finer -
scale regional climate models to compare the current climate to one without warming.
A team at the University of Oxford in the UK, led by Myles Allen and Friederike Otto, used thousands of iterations of
regional climate models embedded within larger global models to examine more localized weather events.
In collaboration with the National Center for Atmospheric Research, Leung has been developing and applying
advanced regional climate models that will help improve the predictions of climate change and its impacts.

different regional climate models.
In some cases, the future projections for the local effects rely on
several regional climate models (RCMs) but only a few GCMs (e.g. the projections for river flow involves 4 GCMs and 7 RCMs).
For those who want to follow the news
about regional climate modelling efforts, there is a live streaming at the conference website, and through twitter with hash tag «#CORDEX2013 `, you can take part in the discussions (please indicate to whom you address your questions).
Combining analysis of observed climate data with global and
regional climate models GREENICE focuses on the atmosphere's response to changes in ocean heat, sea ice and snow cover.
