The Lightning Warning method is mainly using the LSTM deep neural networks with convolutional coding structure to atmospheric electricity field strength Degrees of data and lighting location data are handled, are predicted.On the one hand, since the LSTM deep neural networks with convolutional coding structure have There are long Memorability, the correlated characteristic before thunder and lightning can be occurred well in short-term to remain, better foundation is provided for prediction. On the other hand, since the LSTM deep neural networks with convolutional coding structure have convolutional coding structure, the space in data can be tied Structure feature extraction comes out, and further increases the precision and accuracy rate of prediction.
The process flow of the Lightning Warning method includes the following steps:
Step 1:Data acquire
The electric field region of the atmospheric electric field detector equipment detection used in this application example is limited in scope, so this application example For some areas Lightning Warning, here is the data source of this application example.
(1) it utilizes atmospheric electric field detector to acquire atmospheric electric field intensity data information, air can be depicted using drawing tool The change curve of electric field strength understands the change conditions of atmospheric electric field intensity accurate and visually.
(2) the lighting location data information occurred within the scope of Lighting position machine pickup area is utilized, includes mainly thunder and lightning The attribute informations such as the height when time of generation, the position (latitude and longitude information) of the generation of thunder and lightning, thunder and lightning occur apart from ground.
Step 2:Feature extraction
The extraction of data characteristics is necessary, and is also important.In this application example, according to the periodicity of thunder and lightning, wink It is as follows that the features such as Shi Xing, mobility, has carried out targetedly feature extraction, main feature to the data source of acquisition:
Atmospheric electric field intensity data information correlated characteristic:
(1) as shown in Fig. 6 to 9, it is characterized as that smooth polarity upset, this feature show thunderstorm group close to electric field in Fig. 6 to 9 Instrument or the process for leaving electric field instrument.Under normal conditions, the close initial mark of thundercloud is that field strength is born by just switching to, meaning Taste thundercloud and is moved toward overhead.Watch window at least 40 minutes.Sliding window (width:10 minutes, step-length 1 minute) in whether have Polarity is smoothly overturn, including from positive to negative and from negative to positive, is had, and is set to 1, is otherwise 0.
(2) as shown in Figure 10, it is characterized as that degree of jitter, this feature represent the violent journey of thunderstorm group energy variation in Figure 10 Degree generally means that nearby there is lightning stroke.The definition shaken greatly:Short time (be defined as 1 minute) electric field intensity inside high change dramatically with It is rapid afterwards to restore.The value of this variable is the amplitude peak of all big shakes in watch window.
(3) as shown in figure 11, it is characterized as that steepness, this feature description thunderstorm roll into a ball fuel deposition rate, that is, electricity in Figure 11 Field intensity value Ramp Rate:A how many minute electric-field strengths increase Mkv/m.The feelings that electric field absolute value does not thunder when big but very flat When condition, the time of being climbed is longer.
(4) this is characterized as electric field strength maximum value, this feature description size of thundercloud energy.
Lighting Position Data correlated characteristic information:
(5) short distance thunder and lightning total quantity
(6) the thunder and lightning cloud of guard plot dodges and ground dodges ratio:Because thunderstorm group generates the rule for having ground after first cloud, cloud than with Thunderstorm group's life cycle is related, which represents thunderstorm group maturity feature.
(8) the thunderstorm closing speed of guard plot:Speed of the nearest position in distance protection area of thunderstorm group close to guard plot.
(9) a 50*50 network is built, each lattice in grid represents 1 square kilometre, if there is several thunders It is several that electricity, which falls and just marks the value of the grid within a grid, such as:There are 5 thunders and lightnings to fall in a certain grid, just marks the grid Value is 5.We just obtain the matrix of a 50*50 in this way.
Step 3:Build model
The model that the present invention uses is a basic model LSTM (the Long Short Term based on common RNN Memory it) improves.Since LSTM has the loop body containing loop structure, referring to Figure 12, its information for front Feature, which has, retains memory function, therefore it can be predicted according to the temporal aspect of front well.But our data In contain spatial data information, if direct construction LSTM networks, we may lose the space characteristics of spatial data.Then, We add convolutional coding structure in LSTM neural networks, we have just obtained the model of our needs with convolutional coding structure at this time LSTM deep neural networks, our spatial information in this way can be extracted well.At this point, the band that we obtain There are the LSTM deep neural networks of convolutional coding structure to be provided simultaneously with memory function and spatial information feature extraction functions, further carries The high precision and accuracy of Lightning Warning model.
Step 4:Training pattern
In this application example, the LSTM deep neural networks with convolutional coding structure of use are trained data, will A row vector is formed by the feature (the one before feature in feature extraction) of extraction in every six minutes, the 9th matrix character is carried out The feature obtained after process of convolution carries out conversion and becomes one-dimensional row vector, and splicing composition one is then carried out with the row vector of front The row vector of bigger.According to such regulation, we are the 2016 and 2017 electric-field strength number of degrees in Beijing world Capital Airport Processing and feature extraction are carried out according to lightning data, then labeling.After handling data set well, we first press data set Certain proportion (7:3) be divided into two parts training set and test set, then training set be brought into we structure carry convolution knot Study is trained in the LSTM deep neural network models of structure, wherein loss function is to intersect entropy function, is declined using gradient Algorithm is iterated until obtaining best weight parameter.
Step 5:Assessment models
