We developed a dataset of local-scale daily climate change scenarios for Japan (called ELPIS-JP) using the stochastic weather generators (WGs) LARS-WG and, in part, WXGEN. The ELPIS-JP dataset is based on the observed (or estimated) daily weather data for seven climatic variables (daily mean, maximum and minimum temperatures; precipitation; solar radiation; relative humidity; and wind speed) at...
to teach english adequately, qualified teachers are needed. unfortunately, there are still teachers who are teaching english without an academic degree in tefl. it is necessary for teachers to have a major in english to have subject knowledge, but it is not sufficient. teachers need to have an understanding of the social, cultural, moral, ethical, and pedagogical issues of education and practic...
A Study of the Potential Impact of Climate Change on the Future Droughts in Iran by Using the Global Circulation Models as Outputs Gholamreza Roshan Assistant Professor in climatology, Department of Geography, Golestan University, Gorgan, Iran Mohammad Saeed Najafi MSc Student in Climatology, Faculty of Geography, Tehran University, Tehran, Iran. Extended Abstract 1- Introductio...
Waste disposal in the current situation, which quantity and variety of waste are increasing, needs not only effective management principles but also depends on environmentally-friendly methods to put as less environmental footprint as possible. This study aims to assess the energy consumption, emission of greenhouse gases and air pollutants which normally produce during various waste management...
increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...
This study describes a simple parameterization to estimate regionally averaged changes in surface ozone due to past or future changes in anthropogenic precursor emissions based on results from 14 global chemistry transport models. The method successfully reproduces the results of full simulations with these models. For a given emission scenario it provides the ensemble mean surface ozone change...
Abstract Precipitation patterns are expected to change in the future climate, affecting humans through a number of factors. Global climate models (GCM) our best tools for projecting large-scale changes but they cannot make reliable projections locally. To abate this problem, we have downscaled three GCMs with Weather Research and Forecasting (WRF) model 50 km horizontal resolution over South Am...
We compare future changes in global mean temperature in response to different future scenarios which, for the first time, arise from emission-driven rather than concentration-driven perturbed parameter ensemble of a global climate model (GCM). These new GCM simulations sample uncertainties in atmospheric feedbacks, land carbon cycle, ocean physics and aerosol sulphur cycle processes. We find br...
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...
Background: Changes in temperature and precipitation pattern seriously affect the amount of river runoff coming into Dam Lake. These changes could influence the operating conditions of reservoir systems such as Jor hydropower reservoir system (Malaysia) with the total capacity of 150 MW. So, it is necessary to analyze the effect of changes in weather parameters on the river runoff and consequen...
