The Arctic Regional Climate Model Intercomparison (ARCMIP) aims to improve the simulation of the Arctic regional climate in numerical models. The primary ARCMIP activities focus on coordinated simulations by different regional climate models and general circulation models.
This project network intends to co-ordinate efforts within the Nordic countries to improve the quality of climate change and other regional model simulations for the Arctic as well as for the Nordic countries. This involves improving existing atmospheric regional climate models (RCMs) for the Nordic regions as well as for the Arctic.
There are two overall aims of the project. The first is to estimate probable changes in the regional climate in Northern Europe, bordering sea areas and major parts of the Arctic ("our region"), given a global climate change. The second is to quantify, as far as possible, uncertainties in these estimates, inter alia, by investigating the significance of regional scale climate forcings pertaining specifically to our region.
The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and UNEP to assess scientific, technical and socio- economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. It is open to all Members of the UN and of WMO.
PRUDENCE is part of a co-operative cluster of projects exploring future changes in extreme events in response to global warming.
The Land-Atmosphere System is a coordinated program to examine the geographical patterns and controls over climate-land surface exchange and develop reasonable scenarios of future change in the Arctic.
The atmospheric component of the IARC Plan has two primary objectives. The first is to enhance simulation of the arctic atmosphere by large-scale climate models. The underlying premise is that simulations of arctic feedbacks to global change will be credible only if the characteristics and sensitivities of the arctic atmosphere are captured realistically by models. The second objective is to bridge studies of arctic weather and climate in a way that furthers our understanding of arctic climate and weather interactions, including, first, the effects of climate change on the occurrence of high-impact weather events and, second, the contribution of systematic changes of weather to climate change in the Arctic.
