The El Niño-Southern Oscillation (ENSO) in the tropical Pacific Ocean is of key importance to global climate and weather. However, state-of-the-art climate models still disagree on the ENSO's response under climate change. The potential role of atmospheric ozone changes in this context has not been explored before. Here we show that differences between typical model representations of ozone can...
introduction today, with the increasing population and the need for strategic and industrial crops the farmers are simulated to grow these kinds of crops. thus, this subject has now been caused the inappropriate use of land and natural resources. on the other hand, the natural environment resources have limited the ability to use its resources and the climate change intensifies this limit abili...
Palaeoclimatic data document a sensitive climate system subject to large and perhaps difficult-to-predict abrupt changes. These data suggest that neither the sensitivity nor the variability of the climate are fully captured in some climate-change projections, such as the Intergovernmental Panel on Climate Change (IPCC) Summary for Policymakers. Because larger, faster and less-expected climate c...
Aim NARCliM (NSW/ACT Regional Climate Modelling project) is a regional climate modelling project designed to provide regional climate change data for use in impacts and adaptation research across sectors. Method The climate models used were carefully chosen to satisfy the following criteria: The chosen models perform adequately for the recent past compared to observations. The chosen models...
Anthropogenically induced climate change is of great current interest because of increases in atmospheric loading of infrared active (greenhouse) gases over the past 150 years and the inferred resultant increase in infrared radiation flux in the troposphere. However the climate change ascribed to such increases, not to mention predictions of future climate change in response to prospective chan...
[1] We utilize the GISS Global Climate Middle Atmosphere Model and eight different climate change experiments, many of them focused on stratospheric climate forcings, to assess the relative influence of tropospheric and stratospheric climate change on the extratropical circulation indices (Arctic Oscillation, AO; North Atlantic Oscillation, NAO). The experiments are run in two different ways: w...
Increasing atmospheric anomalies have altered some of the extreme events such as global warming droughts, many climatic components such as precipitation, evapotranspiration, temporal and spatial distribution of precipitation, followed by dominoes of changes in freshwater resources available to communities. Human changes such as changes in the hydrological regime of rivers, changes in the qualit...
statistical modeling of future lake level under climatic conditions, case study of urmia lake (iran)
the present research focuses on the changes of urmia lake level. for this purpose, two timescales have been considered. the trend changes of temperature, precipitation rate and quantitative values of climate type for the observational period from 1968 to 2011 (past scale) and from 2011 to 2100 (future scale) have been analyzed. general circulation model (gcm) is considered for simulating the va...
