Growth must occur in short summer bursts lasting only a few days, a few weeks, or a month or two, depending upon such diverse factors as latitude, seasonal snowpacks, elevation, topographic orientation, wind, and moisture, in both the substrate and the atmosphere.
The spatial arrangement of watersheds where fires present similar orientation suggests wind as a major driver of the broader patterns found in this study.
For WT testing, unsteady pressure measurements were performed in an open jet WT for different telescope orientations and wind speeds, using a number of pressure taps distributed around the inner and the outer surfaces of the enclosure and on the primary mirror surface.
In the context of population connectivity, it is proposed that proximate estuaries and rias of western Iberia are inter-linked populations sharing similar conditions of dispersal and retention, including coastline orientation, alternating winds during late winter and spring, and river plumes.
This model includes variable blade-positioning angle β, the trajectory-shape coefficient CF, and the wind orientation angle φ.
Depending on its orientation to the wind direction, the same structure can perform as a windcatcher or a windextractor.
This aids prey location and orientation relative to wind, but would not work in a fluid medium (Krapf 1986; Meßlinger 1987).
Fig. 3 Billboard with "I didn't vote Obama" sticker signals the political orientation of a wind power supporter in Oregon (L. Hamilton photo, July 2013).
The study was carried out on 15 Italian cities, which were analysed in relation both to urban form and the relationship between grid orientation and local wind conditions.
Based on the results, two design measures are proposed, i.e., keep AFC running during emergency and train orientation against prevailing wind direction.
An initial basic mesh optimization was completed only on the maple seed and samara blades with at the zero angle of attack and zero pitch orientation with a wind speed of 15 m/s.
