the dynamic pressure of the wind is wp = 0.5 · ro · v2 where wp is the wind pressure [kN / m2], ro is the air density [kg / m3] and v is the wind speed [ m / s
Pressure-Probe Methods for Determining Wind Speed and Direction. D. W. Bryer and R. C. Pankhurst. HMSO, London, 1971. 126 pp. Illustrated. 3.50. The literature on pressure probes is so voluminous, and the merit of some of it so doubtful, that this critical review will be most valuable...
The device has a frame (1), control buttons (3), a pressure sensor and a programmed electronic device for converting initial data into a graph displayable on a high luminous display screen (2). The frame has push buttons permitting to control preprogrammed functions of the device and permittin...
The relationship between the two common measures of tropical cyclone intensity, the central pressure deficit and the peak near-surface wind speed, is a long-standing problem in tropical meteorology that has been approximated empirically yet lacks physical understanding. Here we provide theoretical groundi...
An alternative explanation for cross-wind movement is that it is a response to environmental features that are associated with the predominant winds, such as pressure ridges74. However, environmental features cannot account for the association between bear orientation and wind speed or presence of dayl...

As the second step, the same global wind maps are used to derive the required weather forecast by considering the respective mathematical models of wave, ocean and tidal current, ice, atmospheric pressure and temperature conditions. The erroneous data conditions in wind information can introduce ...
The low-speed WindFree™ Cooling features a quiet operation that minimized ambient noise, so it generates much less noise⁵. A wall-mounted WindFree AC is on. When WindFree mode is off, it is noisy at 80 dB. When WindFree mode is on, it decreases to 23 dB and becomes quieter. ...
This suggests that both high-pressure systems identified in Fig. 3 initiated WWB events. It was shown that both hemispheres are involved with the commencement of the WWBs. Nevertheless, only the Northern Hemisphere has been explained; further investigation is needed for the Southern Hemisphere. ...
3Altmetric Metrics Abstract Mitigating climate change demands a transition towards renewable electricity generation, with wind power being a particularly promising technology. Long periods either of high or of low wind therefore essentially define the necessary amount of storage to balance the power system...
