Abstract: A system for measuring wind direction and velocity utilizing a sphere which is capable of making differential orthogonal pressure measurements, using pressure sensors located inside the sphere along apertures forming orthogonal axes of the sphere. The preferred embodiment applies the Bernoulli principle to the sphere which has the apertures disposed along the orthogonal axes, and which measures the wind velocity and direction, whereas an alternative embodiment applies the Reynold's principle by using a sphere having no apertures therein, and resulting in a more robust meteorological measurement device which can also measure other meteorological data which is combined with the wind data to produce forecasting of air and weather patterns in a localized area.
