Title

NUMERICAL SIMULATION THE EFFECTS OF LAKE URMIA DRYING UP ON THE TEMPERATURE REGIME OF MARAGHEH CITY

Pages

Abstract

  The Atmosphere is characterized by phenomena whose space and time scales cover a very wide range. The space scales of these features are determined by their typical size or wavelength, and the time scales by their typical lifetime or period. In reality none of these phenomena is discrete but part of a continuum; therefore it is not surprising that attempts to divide atmospheric phenomena into distinct classes have resulted in disagreement with regard to the scale limits. Most classification schemes use the characteristic horizontal distance scale as the sole criterion. The thermal and dynamic property of water bodies (oceans, seas, lakes, etc.) makes them very important stores and transporters of energy and mass. The exchanges occurring at the air/water interface are, however, complicated by the fact that water is a fluid. This means that heat transfer within water is possible not only by conduction and radiation, but also by convection and advection. As in the atmosphere these modes of transfer greatly facilitate heat transport and mixing, and thereby allow heat gains or losses to be spread throughout a large volume. Although water is not compressible like air, it can be deformed, giving surface waves (Oke, 1978: 85) Such conditions lead to the development of special instability phenomena such as miniature whirlwinds known as ‘dust devils’, and a whole range of unusual optical effects. These include the ‘shimmering’ of objects viewed through the lower atmosphere, and the well-known mirage, both of which are due to the refraction of light as it passes through media of different density. Shimmering is caused by multiple refraction of light as it passes from the object through a field of vertically-arranged filaments of air of differing density. A mirage is caused by the refraction of light from the sky as it passes through the horizontal temperature (density) stratification of the lower atmosphere, and the amount of bending depends on the lapse rate. Land cover and land use are included in influencing factors on climatic elements in particular temperature regime in spatial and temporal scales. Lakes are considered as natural controls on temperature and moisture regime in interior continents. However, any change in hydro climatic conditions of lakes such as increase or decrease of their levels is reflected into climatic conditions of lake surroundings. Nowadays in Iran there is a national challenging debate because severe fall of water level of Lake Urmia and its likely drying up in near future. This paper analyses the temperature regime of surroundings area of URMIA LAKE while it drying up by using TAPM MODEL. Of course, it is obvious the changes will not be limited to temperature regime and involved all of the climatic elements and factors.
