The variability of North Atlantic Subtropical High and its inlfuence on the behavior of tropical cyclogenesis are charactized an analized. The monthly database of the Center for Environmental Prediction and the Center for Atmospheric Research of the United States was consulted, for the months of May to October between 1950-2019. The variables used were the central pressure to determine the position of the North Atlantic Subtropical Anticyclone on the surface, and the geopotential to obtain the position of the anticyclonic center at 850 hPa, as well as the geopotential at 500 and 200 hPa over the central región of the anticyclone. on surface. The results showed that this system weakens at surface level and intensifies at other tropospheric levels and has moved to the northwest with respect to its mean position. On the other hand, the relationship with tropical cyclone activity in the Atlantic basin was assured and updated. Currently, low levels play an important role in tropical cyclogenesis, surface pressure, as well as the intensity and position of the anticyclonic cell at 850 hPa, as well as the position and extension of the anticyclonic ridge at this level, the parameters with highest coincidence. The anticyclone parameters in May maintain great significance, but in the present century the anticyclone parameters in the months of June and July have increased their significance in terms of their position and intensity respectively.
