The trajectories of the particles of the cross-equatorial air current moving in the Julymean 700 mb topographic field of the northern hemisphere are calculated, The correspond-ing annulus experiments are made for comparison wtth the calculation. The calculation and the experiment show that the trajectories of the southern currentparticles entering the low northern atmosphere and moving inertially in the barotropic atmos-phere deflect eastward and then turn back to the equator. The southwest current of themonsoon forms only when the air particles are affected by the Coriolis force and the forceof thermodynamic field of the atmosphere. In the formation of the southwest air currentof the monsoon the β-effect plays a certain role, but it is not a decisive factor. The results of the calculation and the experiment are compared with the real trajecto-ries of the drifted superpressure balloons observed by the satellite.
