FIELD-ALIGNED IRREGULARITIES IN THE ES REGION
Abstract
A comparison of the known diurnal and seasonal behavior of constant height (E sub sc) AND SEQUENTIAL (E sub ss) sporadic-E echoes with that of field-aligned (E sub d) echoes from the E-region indicated that an increase in occurrence of E sub d echoes generally coincided with an increase in occurrence and/or range spreading of E sub sc echoes, but was independent of the presence of E sub ss echoes. A detailed comparison indicated that at night in October and in day- and night-time in December almost all E sub sc clouds detected at frequencies at least down to 2.5 Mc/s have irregularities which are field-aligned.
