Abstract: 

Introduction:Precipitation and temperature patterns have especial role in the accuracy of hydrologic models. future patterns of rainfall and temperature can lead to better hydrological predictions. Hence, according to their importance, we try to derive the future rain and temperature patterns of the Gharehsoo River’s watershed. This watershed is in the northwest of Iran in the Ardebil province and it has high amount of agriculture productions. Interpolation schemes are utilized in this study to determine rain and temperature patterns. The utilized software package is ArcGIS software.

Abstract: 

Introduction:Iran is located in the south-west of Asia and is in the arid belt of the world and about 60% of the extent of the country is mountainous and the remaining part (1/3) is desert and arid land. Climate of the country can be divided into three main categories: -Warm temperate, rainy with dry summer in a narrow strip in the north, -Dry, hot desert in the central plateau, -Dry, hot steppe covering the rest of the country. Then, it could be so difficult to predict climate change over whole of the country.

Abstract: 

Introduction:Between different factors, atmosphere conditions are most important natural factors which affect the agricultural crops production. One can observe these effects as frost, sunstroke, outbreak of pest and etc. At the moment, agriculture is one of the most important sections in the economy of a country. In fact, one can say that economic growth is impossible without agriculture. Agricultural crops growth is widely dependent to the atmosphere conditions. Light, temperature, co2, water and nutrients are controlled by the atmosphere. Cultivation of crops in sites with compatible conditions for them has two results.

Abstract: 

Introduction:Citrus fruits are ranking in the first place in the world with respect to production among fruits. They are grown commercially in more than 50 countries around the world. Citrus fruit production recorded a handsome increase during the 1990s, and recently reached 100 million tons annually. Considering the therapeutic value of these fruits and the general health awareness among the public, citrus fruit are gaining importance worldwide, and fresh fruit consumption is likely to increase.

Abstract: 

Introduction:Air pollution in megacities is influenced by many factors such as topography, meteorology conditions, industrial growth, transportation systems, and increasing populations. Urban/industrial emissions from the developed world, and increasingly from the megacities of the developing world, change the chemical content of the downwind troposphere in a number of fundamental ways. Atmospheric pollution is becoming an increasingly critical problem to human health and welfare especially in megapolises. In fact, many factors affect air pollution and concentration of pollutants.

Abstract: 

Introduction:Sea Surface Temperature (SST) is a critical factor in humidity providing and climatic structure of the regions mainly surrounded by oceans and seas. Major amount of humidity resources of Iran is provided by regional water bodies of Caspian, Oman, Mediterranean and Black Seas, Persian Gulf and North of the Indian Ocean (Alijani 1999: 221).

Abstract: 

Introduction:Forecasting sea conditions and its vital role in shipping, fisheries and professional affairs, is too obvious. Different models, accuracy and precision in this regard can effectively lead to a better understanding. One of the useful models is SWAN. For evaluating the performance of this model in aspect of executive and scientific both, study on verification of its products is required. In this study, the model outputs of wave height and period in the case of Bushehr and Assaluyeh have been verified. With this study it is tried on the accuracy of the model outputs with the corresponding values of Buoy and its performance on predictions 12, 24, 48, 72 and 96 hours studied and assessed.

Abstract: 

Drought is a severe dilemma which influences different aspects of mankind’s life. Drought has a negative impact on economy, environment and agricultural sector and cause heavy damage and losses in many parts of the world. Therefore the quantitative estimation and prediction of drought phenomena has become an important issue for policy makers and the scientific community. In the last three decades, remote sensing has provided a useful tool for drought monitoring and a variety of remotely sensed drought indices based on vegetation indices, land surface temperature (LST) and albedo, have been developed.
