Electrical storm forecast system

Claim 1

A storm forecast system including a sensor unit for receiving electrostatic field information, an amplitude and phase detector coupled to said sensor unit, and information processing means coupled to said amplitude phase detector, said system comprising: (a) sensor board means (26) having two alternately conductive sections (A, B) radially disposed around a center; (b) a rotor (22) with blades corresponding to said sections for rotation in a plane adjacent to said sensor board means; (c) first and second resistors (R3, R4) in series with a center point, said resistors each having an outer end coupled to one of said sections; (d) first and second field effect transistors (Q1, Q2) coupled to said first and second resistors, said field effect transistors each having an output side; (e) a transformer (T1) with a center tapped primary and a secondary winding, said primary winding having two ends, one end each being connected to an output side; (f) a rotating phase reference generator (28) coupled to said sensing board means (2b); (g) a phase detector including first and second diodes (D1, D2); (h) amplifier means coupling the output of said sensor unit to said phase detector; and, (i) recorder terminals for coupling a recorder to said phase detector.
