WebIonospheric disturbances are a short-term deviation from regular climatology (such as diurnal variations). These disturbances can be local, regional, and sometimes global. A large category of these disturbances has characteristic wave properties in propagation and periodicity and is specifically termed as traveling ionospheric disturbances (TIDs). WebBecause changes in D-region electron density affect the conductivity of the ionosphere, nighttime lightning discharges can perturb the amplitude and phase of VLF communication signals propagating through the Earth-ionosphere waveguide. Most past work in this area has involved unique propagation paths between a transmitter and receiver.
