“…While being based on data relating to several countries of the Gulf, in particular, the sites of Saudi Arabia, Sabbagh et al developed two empirical relations binding the various weather parameters which affect the attenuation of the solar radiation, namely: sunshineduration, relative humidity, the maximum temperature, the altitude, the geographical situation (longitude, latitude) and its situation compared to the sea and a lake of water characterized by the characteristic factor of the zone, which is given by the following relation [37]:…”

The aim of this study is the determination of a suitable solar radiation model for the twelve cities of Chad based on meteorological data. Three appropriate models are used to estimate the solar radiation of each site. The choice of these models is based on statistical tests such as the Root Mean Square Error (RMSE), the Mean Bias Error (MBE), the Mean Percentage Error (MPE), and the Nash-Sutcliffe Equation ( KeywordsGlobal Solar Radiation, Sabbagh, Allen, Angstrom-Prescott, Meteorological Data How to cite this paper: Soulouknga, M.H.,

“…The availability of meteorological parameters, which are used as the input of radiation models, is the key factor in choosing the proper radiation models at any location. Many researches have been done in this field and some methods such as Angstrom (1924), Paltridge (1976), Sabbagh (1977) and Daneshyar (1978) have been proposed for evaluating solar radiation each of which has its own input parameters. In this study Sabbagh method has been used due to adaptability and availability of data in Iran.…”

ABSTRACT:Drought is among the natural disaster that causes damages and affects many people's life in many part of the world including in Iran. Recently, some factors such as climate variability and the impact of climate change have influenced drought frequency and intensity in many parts of the world. Drought can be divided into four categories of meteorological, hydrological, agricultural and socialeconomic. In meteorological the important feature is lack of rainfall. In hydrological drought river flows and dam storage are considered. Lack of soil moisture is the key factor in agricultural droughts while in social-economic type of drought the relation between supply and demand and social-economic damages due to water deficiency is studied. While the first three types relates to the lack of some hydrological characteristics, social-economic type of drought is actually the consequence of other types expressed in monetary values. Many indices are used in assessing drought; each has its own advantages and disadvantages and can be used for specific types of drought. Therefore knowing the types of drought can provide a better understanding of shortages and their characteristics. Drought vulnerability is a concept which shows the likelihood of damages from hazard in a particular place by focusing on the system status prior to the disaster. Drought vulnerability has been viewed as a potential for losses in the region due to water deficiency at the time of drought. In this study the application of vulnerability concept in drought management in East Azarbaijan province in Iran is investigated by providing vulnerability maps which demonstrates spatial characteristics of drought vulnerability. In the first step, certain governing parameters in drought analysis such as precipitation, temperature, land use, topography, solar radiation and ground water elevation have been investigated in the region. They are described in details and calculated in suitable time series. Vulnerabilities are ranked in 5 intervals and for each parameter vulnerability maps are prepared in GIS environment. Selection of theses parameters are based on factors such as regional features and availability of data. Considering the fact that the aforementioned parameters have different level of importance in vulnerability maps, different weights are assigned to the parameters considering how critical each parameter is in the overall drought analysis. Expert's opinion is selected in assigning weights. A multi-criteria decision making (MCDM) framework is used to check the consistency of the provided information. Then the weighted maps are overlaid to find the overall vulnerability map. The map shows very low, low, medium, intense and very intense regional vulnerabilities. According to the results, the west part of East Azarbaijan province is the most vulnerable region to drought which is expected due to the vicinity of this part to Urumia Lake that has been lost most of its water during the last decades. The least vulnerable part seems to be the Eastern part ...

“…Löf et al (1966a, b) is a set of refined monthly world maps of solar global radiation, showing more details than Budyko's maps. At the national level, the following atlases/maps were published, mainly based on measured fluxes: the global solar radiation for U.S.A. by Bennett (1965), Mexico by Almanza and López (1978), Greece by Katsoulis and Papachristopoulos (1978), Saudi Arabia by Sabbagh et al (1977), North America including Canada by Bennett (1967), South Africa and Namibia by South Africa Weather Bureau (1965), China by Zuo et al (1963) and Zuo (1963). The latter work by Zuo (1963) also contains radiation balance.…”

Energy balance climatology emerged from the 19th century thermodynamics and radiation research. Energy balance consideration offered an attractive intellectual ground to apply the conservation principle to a natural process. The climate system was often compared to the processes in a steam engine. Research into this field started with insufficient theory of radiation and turbulence, primitive instruments, and limited observational data. In the course of the last 150 years, energy balance climatology gradually gathered advanced theories, continuously improved instruments, newly acquired observation platforms, such as space, and high performance computational capability. In the present article, the processes of climate formation are examined by going back to the principle of energy conservation. Further, the development of this branch of science is presented in five stages characterized by similar stages of theoretical and technical progress. This review visits important steps in the course of these developments and examines their value in reaching the present stage of knowledge. Although the achievements of the last 150 years are impressive, the present understanding of energy balance is far from sufficient. The main problem stems from the fact that the scientific community has not fully used the outcome of laboratory experiments and precision field observations. As high-quality observations are presently being made throughout the entire world, a new and improved knowledge of energy balance will become available in the near future.
