A description, pertinent to the HF communications engineer, of the high latitude ionosphere is given. The impact of this disturbed geophysical environment on communications systems is described, and some frequency management techniques to avoid potential system outages are outlined. Reference is made to long term ionospheric predictions and short term ionospheric forecasts.
