    • A system and method for predicting the probability of cloud-to-ground lightning strikes, ‘frequent’, more than 2 strikes per minute on average, cloud to ground lightning strikes, and/or ‘numerous’, more than 4 strikes per minute on average, through the use of polarimetric radar is presented. The data volume created by the polarimetric radar is processed to identify the type of hydrometeors in each range cell. For each vertical column, the maximum height of the graupel is compared to the lowest height of ice crystals in the volume. In the event that the lowest height of ice crystals is ambiguous, the height of the temperature where ice crystals form, −10° C., may be substituted for the lowest height of the ice crystals. Probability density functions are applied to the height difference to determine the probability of cloud to ground lightning within the column. Lightning probability product data are displayed on a visualization system in a georeferenced manner providing georeferenced lightning warnings. A forecast of the probabilities of cloud-to-ground lightning is determined by simple translation using storm track properties.

    • A long-range lightning detection and characterization system and method. Electromagnetic radiation produced by a lightning strike is sensed at a sensing location and a measured signal representative of the strike is produced that defines an amplitude versus time. A set of reference data containing waveforms comparable to the measured signal is established. The set of reference data defines a set of reference amplitudes versus time, representative of one or more predetermined reference lightning strikes at various predetermined distances, where for each of the distances, the reference lightning strikes have associated therewith various predetermined day/night percentages. The measured signal is compared with the reference data, the comparison including finding a correlation between the measured signal and a correlating waveform in the reference data. At least one of a propagation distance, a time-of-arrival, a polarity, and an amplitude of the measured signal is inferred by reference to the correlating waveform.

    • A lightning detector designed for aircraft carried applications provides for improved lightning discrimination and display. The instrument employs a relatively wide band receiver so as to retain the received waveform or digital replicas thereof. This allows more precise discrimination between desired lightning signals and noise. Signals are processed to provide for effective display of the available information. The display modes that are enabled by the signals include flash and cell mode as well as a combined flash and cell mode. The cell mode provides for generating and displaying a cumulative weight of lightning activity, giving each strike a regional effect as opposed to illustrating it as a point. Color is used to improve the user's grasp of the displayed information; the color illustrating increased intensity from the blue-green to the yellow-red. Flash mode shows locations of the different flashes within the range scale; this mode too may use color for a similar effect. Finally there is a combined flash and cell mode display.

    • A system for detecting turbulence along a path that is subject to turbulence. The system may make use of at least one transmitter to transmit electromagnetic (EM) energy along the path and at least one receiver to receive the EM energy. At least one of the transmitter and the receiver moves along the path. The receiver may have an antenna responsive to incident EM energy to produce a received signal, and an input for accepting a velocity signal indicating a velocity that the receiver or the transmitter is moving. The receiver processes the received signal using the velocity signal to remove a shift associated with the received signal because of relative motion between a source of the EM energy and the receiver or transmitter that is moving along the path. Thus, the receiver determines an alteration of the EM energy caused by the turbulence and outputs a signal indicative of the turbulence.
