Paper deals with involvement of external meteorological influences on the shape of Heat Supply Daily Diagram (HSDD), such as air temperature, wind velocity, wind direction, exposure (intensity of solar radiation), air humidity and air pressure. Inclusion of these weather influences results in improvement of HSDD forecast.

HF radar can be employed to measure sea surface state parameters such as waveheight, wind field and surface current velocity. This paper describes the application of the high frequency ground wave radar in remote sensing the surface conditions over the Eastern China Sea in October, 2000. The radar, referred to as the OSMAR2000, was developed by Wuhan University. Preliminary wave spectra, wavehe...

abstract in general, garmesh wind in rasht province increases the temperature by 9°c and reduces relative humidity by 47%. the direction of prevailing wind during the garmesh wind is southern and its average speed increases by 2 m/s to 5 m/s. the highest frequency of garmesh wind occurs at 09 and 12 utc in december and january. the occurrence of this phenomenon substantially increases the horiz...

this article is a comparative evaluation of airflow in two kinds of yazdi and kermani wind-towers. in the late decades of twenty century regarding to high population growth rate and energy crisis, vernacular architecture and its passive methods for gaining thermal comfort, has been strongly focused. moreover, a huge scientific movement setup for researches deep in exploring passive cooling and ...

urbanization expanse and population growth, as well as pilgrim's possibility of some cities provide overuse of vehicles and consequently increased air pollution. thus by considering the importance of the impact of air pollution on human health, in this study, air pollution in terms of pm10 using psi standard index and inverse distance weighting is zoned in mashhad. on the other hand, meteo...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

We investigate experimentally the early stage of the generation of waves by a turbulent wind at the surface of a viscous liquid. The spatio-temporal structure of the surface deformation is analyzed by the optical method Free Surface Synthetic Schlieren, which allows for time-resolved measurements with a micrometric accuracy. Because of the high viscosity of the liquid, the flow induced by the t...

introduction dust storms, one type of dust event, are in most cases the result of turbulent winds, including convective haboobs, which raise large quantities of dust from desert surfaces and reduce visibility to less than 1 km. this dust reaches concentrations in excess of 6000 mg m3 in severe events. the major dust source regions are areas of arid and hyper-arid, with mean annual rainfalls of ...
