                         with exchanges in the Upper Troposphere and Lower Stratosphere and 
                         the relationship between stratospheric ozone and atmospheric 
                         blocking. Eighteen cases of atmospheric blocks that occurred in 
                         the region between the Southeast Pacific and the South Atlantic in 
                         the period between 2000-2015 for the winter months of 
                         June-July-August (JJA) were selected. To describe the processes 
                         that occur in the stratosphere-troposphere coupling, mass flux, 
                         and rates of radiative heating and cooling at high levels of the 
                         atmosphere were evaluated. It was observed that the intrusion of a 
                         stratospheric is characterized by potential anomalies of vorticity 
                         and a high concentration of stratospheric ozone in the atmospheric 
                         column. Through the analysis of the dynamic tropopause and based 
                         on the ozone content within an atmospheric column, the anomalies 
                         of potential vorticity coincided with regions with the largest 
                         amounts of the ozone column and downward flux, favoring the 
                         intrusion of stratospheric ozone into the upper troposphere 
                         region. In the region of the atmospheric block, positive 
                         temperature anomalies higher levels are observed and are 
                         associated with rates of radiative heating/cooling due to 
                         variations in ozone in the stratosphere. Besides, the vorticity 
                         anomalies between 1.5 and 2 PVU contributed to the decrease of the 
                         geopotential height in the tropospheric column that favors the 
                         formation of the atmospheric blocking.",
