Abstract The wind field over an urban lake may exhibit considerable variability due to shielding effects from surrounding structures. Field measurements at reservoir in Singapore were augmented by computational fluid dynamics (CFD) model results develop a the surface via data assimilation approach. identified, depending on structure alignment with prevailing direction, that impacted direction a...

 The flow of air in Sistan Region depends on the direction, speed and continuation of the winds known as “120-day winds of Sistan”. These winds blow over the settlements of the region every year from late May to late September with the dominant direction of NW-SE. During the recent years, there has been a notable increase in the amount wind-blown dust and sand in the residential areas due to cl...

BACKGROUND Understanding how environmental conditions, especially wind, influence birds' flight speeds is a prerequisite for understanding many important aspects of bird flight, including optimal migration strategies, navigation, and compensation for wind drift. Recent developments in tracking technology and the increased availability of data on large-scale weather patterns have made it possibl...

Pollination is the mechanical transfer of male pollen of a flower on the female stigma.This process has a fundamental role to survive the plants species.Since this process is invisible ,its importance has been ignored.Insufficient pollination can be harmful for the farmer instead of being useful.Pollination can be done via some ways.The most important ways are done by insects and wind.Pistachio...

Wind velocity assumes a critical part for measuring the power created by the wind turbines. Nonetheless, power production from wind has a few weaknesses. One significant issue is that wind is a discontinuous energy source which implies that there exists substantial variability in the generation of vigor because of different variables, for example, wind speed. Wind direction is a significant var...

Of the various renewable energy resources, wind power is widely recognized as one of the most promising. The management of wind farms and electricity systems can benefit greatly from the availability of estimates of the probability distribution of wind power generation. However, most research has focused on point forecasting of wind power. In this paper, we develop an approach to producing dens...

introduction population growth, along with the rapid development in industrial and many urban sectors, and lack of sustainable development approach in urban planning are all caused great changes in environment in form of pollution and ravage. in urban environments, complexity of spaces and urban manmade phenomena as well as the lack of regular and continuous measurement of atmospheric elements ...

In the Persian Gulf, the major source of oil pollution is related to the transportation of tankers, offshore production and discharges by coastal refineries. The water dynamical field has been obtained using a new hydrodynamic model. Local wind is recognized as the principal driving force combining to the water dynamic field to determine oil drift on the sea surface. The Weibull probability dis...
