this present research work was carried out to evaluate the energy consumption in a typical iranian building based on the forecast of climatic variables. thus, the lars-wg model was validated for some northwest stations of iran, including tabriz, ardebil, oromieh, kermanshah, hamedan, sannandaj, qazvin, and zanjan. the average monthly outdoor temperature was forecasted from 2011 to 2100. the rel...

Mozambique, like many African countries, is already highly susceptible to climate variability and extreme weather events. Climate change threatens to heighten this vulnerability. In order to evaluate potential impacts and adaptation options for Mozambique, we develop an integrated modelling framework that translates atmospheric changes from general circulation model projections into biophysical...

This paper introduces AMLCS-DA, a Python package designed to perform sequential Data Assimilation (DA) on Atmospheric General Circulation Models (AT-GCM). The provides implementations of well-known ensemble-based methods. default forecast step relies the AT-GCM SPEEDY. Users can define various configurations for assimilation steps, including density observational networks, background error corr...

1. introduction climatic change is one of the most important challenges human beings have confronted with in recent centuries due to its severe effects on water resources, agriculture, energy, tourism and even human bioclimatic. developing strategies, making decisions with awareness about water consumption in different parts in the future, and available water resources management require climat...

Global warming caused by an increase in the concentrations of greenhouse gases, is the direct result of greenhouse gas-induced radiative forcing. When a doubling of atmospheric carbon dioxide is considered, this forcing differed substantially among 15 atmospheric general circulation models. Although there are several potential causes, the largest contributor was the carbon dioxide radiation par...

today, climate change is one of the most important scientific and even the political – social issues. the causes of climate change can be divided into natural and human - made. natural factors have the long-term performance and long history, such as the cycle of solar activity, dusts and gases of volcanic eruptions, geodetic and static agents and etc. human-made factors was mainly formed and ac...

Northern Hemisphere atmospheric blocking as simulated by 15 atmospheric general circulation models in the period 1979–1988 Abstract As a part of the Atmospheric Model Inter-comparison Project (AMIP), the behaviour of 15 general circulation models has been analysed in order to diagnose and compare the ability of the different models in simulating Northern Hemisphere midlatitude atmospheric block...
