Sometimes it is broken by development of meridional circulation
, which causes large fluctuations and sharp changes in the course of meteorological elements [1, 2].
A statistically significant correlation was detected between the atmospheric circulation indices and storminess at Vilsandi, while the characteristics of zonal circulation have a positive correlation and those of meridional circulation are related to no or a negative correlation (Jaagus et al.
The three first patterns describe the zonal circulation and the two last ones the meridional circulation.

This study highlights the importance of monitoring and improving measurement of the sun's meridional circulation
In answer to Jim Jones' question, it has been well established that the main driving force behind the meridional circulation
of the North Atlantic conveyor belt, with ultimate worldwide impacts, is the descent of cold high-density saline water into the abyssal ocean at high northern latitudes.
The last two teleconnection patterns represent the meridional circulation
