We present results of an implementation of the Elastic Viscous Plastic (EVP) sea ice dynamics scheme into the Hadley Centre coupled ocean-atmosphere climate model HadCM3. Although the large-scale simulation of sea ice in HadCM3 is quite good with this model, the lack of a full dynamical model leads to errors in the detailed representation of sea ice and limits our confidence in its future predi...

We combine the ensembles from two different experiments to study the climate sensitivity of the HadSM3 climate model subject to parametric uncertainty. We use a statistical framework based around linked emulators, where expert judgements are required to quantify the relationship between the two ensembles. Detailed diagnostics are presented. As an application, we perform a sensitivity analysis f...

[1] We explore the potential predictability of rapid changes in the Atlantic meridional overturning circulation (MOC) using a coupled global climate model (HadCM3). Rapid changes in the temperature and salinity of surface water in the Nordic Seas, and the flow of dense water through Denmark Strait, are found to be precursors to rapid changes in the model’s MOC, with a lead time of around 10 yea...

abstract the most important part of the design and operation of the supplier systems of agricultural water requirement is the estimating of plant water requirement. in this study by using the lars-wg5 model, downscaled the data of hadcm3 model according a1b, a2 and b1 scenarios that confirmed by ipcc, and was simulated monthly amounts of precipitation, minimum temperature, maximum temperature a...

This study focuses on the assessment of the spatiotemporal structure of ENSO variability and its winter climate teleconnections to North America in the Intergovernmental Panel on Climate Change’s (IPCC) Fourth Assessment Report (AR4) simulations of twentieth-century climate. The 1950–99 period simulations of six IPCC models are analyzed in an effort to benchmark models in the simulation of this...

abstract the climate change was known to force local hydrology, through changes in the pattern of precipitation, temperature and the other hydrological variables. in this research, the impact of global warming on maximum and minimum temperature, precipitation and evapotranspiration (wheat, corn, tomato and sugar beet) of kashafrood basin under two climate change scenarios (a2 and b2), and the o...

This discussion paper is/has been under review for the journal Earth System Dynamics (ESD). Please refer to the corresponding final paper in ESD if available. Abstract The role of extra-tropical vegetation on the large-scale tropical circulation is examined in the version 3 Hadley Centre Climate Model (HadCM3). Alternative representations of present day vegetation from observations and a dynami...

This study focused on the Upper Manyame sub-catchment which covers an area of approximately 3 786 km2 and forms part catchment, one seven catchments Zimbabwe. catchment has its source in Marondera town drains into Zambezi River downstream Kariba Dam upstream Cahora Bassa Dam, northern country. assessed potential climate change impacts streamflow reservoir inflows sub-catchment. Hydrologic simul...

This study approaches the problem of downscaling global climate model simulations with an emphasis on validating and selecting global models. The downscaling method makes minimal, physically-based corrections to the global simulation while preserving much of the statistics of interannual variability in the climate model. Differences among the downscaled results for simulations of present-day cl...
