SPORADIC E (ES) LAYERS ARE CHARACTERIZED BY DENSITY ENHANCEMENTS IN THE E-REGION OF THE IONOSPHERE THAT VARY FROM SEVERAL TIMES TO AN ORDER OF MAGNITUDE HIGHER THAN BACKGROUND PLASMA DENSITY. UNDERSTANDING THE DYNAMICS AND PHYSICS OF ES LAYERS IS OF CRITICAL IMPORTANCE DUE TO WHAT THEY REVEAL ABOUT THE DYNAMICS AND ELECTRODYNAMICS OF THE IONOSPHERE AND THE AFFECT THESE IONIZED LAYERS HAVE ON VARIOUS RADIO COMMUNICATION SYSTEMS. OUR RECENT WORK HAS SHOWN THAT NEAR THE EQUATOR ES LAYERS ARE PRODUCED NOT JUST BY WIND SHEARS BUT ALSO BY UNDULATIONS IN THE VERTICAL ELECTRIC FIELD HIGHER UP IN THE E REGION. THE UNDULATIONS SEEM TO THEMSELVES BE TRIGGERED BY THE VERY MODULATION OF THE ES LAYER BY THE NIGHT-TIME F REGION DYNAMO THEREBY INTRODUCING A COMPLEX FEEDBACK MECHANISM THAT STRONGLY AFFECTS THE POSITION AND EVOLUTION OF THE LAYER . WE ALSO SHOWED ELECTRON TEMPERATURE DATA THAT CONFIRMED MULTIPLE OBSERVATIONS OF ELECTRON TEMPERATURES AROUND ES LAYERS THAT CAN BE ENHANCED BY UP TO 1000 K. WE MADE A CASE FOR THE HEATING RATE BEING PRODUCED BY PARALLEL CURRENT DENSITIES OF THE ORDER OF 1 TO 2 MICROAMPS/M^2. THESE CURRENTS WERE CAUSED DIRECTLY BY THE F REGION DYNAMO ITSELF IN THE DENSITY TROUGHS WHILE IN THE DENSITY MAXIMA REGIONS THEY WERE TRIGGERED BY A DIVERGENCE IN THE CURRENTS PERPENDICULAR TO THE MAGNETIC FIELD RESULTING FROM THE ES LAYER ITSELF IN THE PRESENCE OF THE OBSERVED F REGION GENERATED ELECTRIC FIELDS.
