%0 Journal Article %T APPLICATIONS OF LAPLACE SPHERICAL FUNCTIONS IN METEOROLOGY %A Ion Isaia %J Present Environment and Sustainable Development %D 2011 %I %X The work tries to show that Laplace spherical functions can be applied in meteorology, too. In other words, some cycles in the evolution of maximum and minimum daily temperatures in the air can be explained by either the applications of these functions, which describe the tidal potential of the atmosphere. Tidal cycles of the atmosphere, explained by applying Laplace spherical functions, are reflected, through (planetary) Rossby waves, in cycles of maximum and minimum daily temperatures in the air, with the same duration. The 20 Laplace spherical functions describe, in a mathematical aspect, the tidal potential of the atmosphere, considering the Earth to be a sphere. Of these, the most important are the zonal, teseral and sectoral spherical functions %K Laplace spherical functions %K tidal potential %K tidal cycles %K cycles of the air temperature %U http://pesd.ro/articole/nr.5/1/06.%20Isaia.pdf
