Despite the potentially strong effect of wind on bird orientation, our understanding of how wind drift affects migrating birds is still very limited. Using data from satellite-based radio telemetry, we analysed the effect of changing winds on the variation of the track direction of individual birds. We studied adults and juveniles of two raptor species, osprey Pandion haliaetus and honey buzzar...
2. STUDY SITES Abstract A method is presented for the mapping of wind speed over the ocean using satellite (ERS-2 SAR, ENVISAT ASAR) and airborne (E-SAR) synthetic aperture radars. Impacts of a large offshore wind farm on the local wind climate are described quantitatively from the radar measurements. Of particular interest is the magnitude and extent of wakes (i.e. regions of reduced wind spee...
Introduction: Leakage from process equipment and the entrance of flammable fluids to surrounding atmosphere may cause flammable gas cloud. The coincidence of flammable gas cloud with ignition source could make flash fire or vapor cloud explosion that cause injury and fatality. The concept of reduction of confluence of flammable gas cloud and potential sources of ignition is known as hazardous a...
In this study, a microelectromechanical system (MEMS) two-dimensional (2D) wind direction and wind speed sensor consisting of a square heating source and four thermopiles was manufactured using the heat detection method. The heating source and thermopiles of the manufactured sensor must be exposed to air to detect wind speed and wind direction. Therefore, there are concerns that the sensor coul...
Background and purpose: Bacterial and fungal bioaerosols play important roles in the atmosphere and have significant effects on human health. This study aimed at investigating the concentration of bioaerosols in ambient air in Shahrekord, Iran during two warm and cold seasons at three different points in 2019. Moreover, the effect of meteorological factors such as temperature, relative humidit...
Aeolian sandstones are found intimately associated with Late Neoproterozoic ‘snowball Earth’ glacial deposits. Studying the nature of these aeolian deposits offers the great potential to elicit new and important information regarding the wind conditions during these extreme glacial intervals. Wind direction is the dominant paleoclimatic indicator that can be derived from aeolian deposits and on...
