Description
Technical field
The present invention relates to lightning monitoring field, particularly relate to a kind of Lightning Warning method and system based on distributed arrangement's lightning monitoring device.
Background technology
Lightning Disaster is one of disaster threatening human life's property safety, accurately carried out early warning tool and be of great significance before Ground flash percussion is raw.At present, two classes are mainly contained to the direct monitoring index system equipment of thunder and lightning:
One is mainly comprise very low frequency (VLF) (VLF) lightning positioning system and very high frequency(VHF) (VHF) cloud sudden strain of a muscle positioning system, wherein the electric discharge event (counterattack) of VLF mainly in Lightning Process carries out identifying and locating, can determine that lightning occurs in the position that point is fought back on ground, to hit the place of causing disaster at fast searching Ground flash afterwards; VHF identifies Lightning radiation and locates, thunder and lightning aerial channels feature can be described, within 5 ~ 15 minutes, to occur prior to Ground flash owing to dodging between cloud, combined by VLF and VHF, the mode that local early warning is carried out in the lightning location after being occurred by calculating far-end thunder and lightning and cloud sudden strain of a muscle location is the outer important Lightning Warning equipment of Now Domestic.But this Lightning Warning equipment is only monitor the electromagnetic wave of thunder and lightning association, is easily disturbed the impact of electric wave, causes the precision of the lightning monitoring in certain limit and warning lower.And the mode of this acquisition early warning information is only adopt time difference method, also have impact on the precision of early warning to a certain extent.
Two is by adopting the electric field intensity of local air to carry out the equipment of monitoring, thus obtains local lightning monitoring and early warning information.Usually, this equipment adopts atmospheric electric field detector as a kind of equipment measuring atmospheric electric field, predicted by potential differentiation, namely be the potential difference (PD) measuring space point-to-point transmission, then the distance divided by point-to-point transmission obtains electric field intensity, its advantage is that structure is simple, measurement range large, be convenient to theory calculate and the demarcation to instrument, but it is easily subject to the interference of nearby device and causes the drift of the data of detection and cause measuring accuracy low.
In addition, current meteorological system, can only on a large scale according to meteorological Doppler radar and satellite information, and large period thunder and lightning forecasts.And in less local, for coming soon, sudden strong, endanger large thunder and lightning, also there is no good forecasting procedure.The lightning forecasting that the Equations of The Second Kind of above-mentioned introduction carries out according to thunder and lightning electric field numerical analysis is the effective ways solving little subrange Lightning Warning.And for can at little subrange (circumference diameter 5 km), the time period carried out Lightning Warning in 1 hour does not also have effective ways.In relatively accurate place and time, an accurate forecast blank is especially carried out to thunderstorm in short-term.And this local thunderstorm has very large harm to many places such as petroleum chemical enterprise, oil depot, refuelling station, tourist attractions, golf courses, particularly combustible and explosive area is very dangerous especially.
Current local thunderstorm early warning carries out single-point forecast-i.e. independent lightning warning device by atmospheric electric field strength investigation instrument.The measurement radius formed centered by device, measure the electric field intensity signal of thunder cloud, can provide in local measurement radius and whether thunder and lightning, thunderstorm early warning occur, but thunderstorm can not be provided and will occur in the trend measuring particular location in radius and thunder cloud, forecast precision and accuracy are restricted, and also very easily occur wrong report and fail to report.
