Stratosphere clouds are captured by stratosphere air currents. and moving in the general direction along the parallel with a speed of about 100 kilometers per hour while stretching in the direction of transfer The speed of movement in the straight direction is several times less. In addition, the clouds scatter in the direction perpendicular to the transfer. Small aerosol gravity sedimentation As in the troposphere it is slow. For example, at an altitude of 33 to 35 kilometers
