Abstract
The poles featuring in this paper stem directly from Maxwell’s classical harmonic polynomials. Here, we employ them in a systematic approach to the representation of wind probability distributions in the plane. Symmetry suggests the number of poles (and the degree of the polynomial) strictly necessary in a specific situation. In this model, multipolar tensors of different ranks (corresponding to homogeneous polynomials of different degrees) embody different components of wind climate. When applied to the data of a wind farm in Sicily (Italy), this strategy proves that an octupolar distribution (with 3 poles) is the best fit. A quadrupolar distribution (with 2 poles) is found to be equivalent to a distribution that is elsewhere called offset elliptical normal.
期刊介绍：
Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics.
Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences.
Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
