The physical processes occurring in the supergranule boundary cylinder layer (SBCL) are investigated. Taking into account the Coriolis force, an expression is obtained for the phi component of the magnetic field and velocity in the SBCL. Within the framework of linear MHD, the formation and coalescence of magnetic tubes (i.e., spicules), in the course of the reconnection of the SBCL magnetic field are considered. The estimated number of spicules appearing on each supergranule cell is in agreement with observations. This number depends on the solar latitude: if the normal component of the magnetic field Bz is assumed to be independent of the solar latitude, then the maximum number of spicules should be at the solar latitude = 71 deg; if Bz is assumed to be the component of the dipolar field Bz about sin the solar latitude, then the maximum number should be at the pole.
