Summary

    The dynamics of Walker-type circulations are thermally direct, and can be thought of as a warming atmospheric column coupling with a cooling column.  Walker-type ciruclations occur on a large-scale, and effect climate variations.  They occur in the meridional direction as a Hadley Cell and a Monsoon Cell, which can be zonally averaged into a Mean Meridional Circulation (MMC); and in the zonal direction as a Walker, Atlantic Walker, and Transverse Monsoon Cell which can be meridionally averaged into a Mean Zonal Circulation (MZC).  Observations of Walker-type cooling and warming columns can be seen using data of vertically integrated heating and vertical velocities. The data can also be used analyze mass continuity in Walker-type cells and determine the closed nature of the circulaion.
