Title: Method for obtaining high-accuracy rainfall prediction value up to several-hours ahead in dam basin based on correlation of interpolated (interpolation) value of rainfall prediction value by low (middle) resolution model and rainfall prediction value (including interpolated value) waveform of high resolution model
Inventor: DOMON YOSHIETSU
IPC: G01W1/10
Filed: 2019-11-13
Abstract: To solve a problem that, in a low (middle) resolution model such as global models GSM, MSM of the Meteorological Agency, a prediction up to several-days ahead becomes possible, and a large-scale rainfall area can be captured, however, on the other hand, in a high-accuracy model such as a local model LFM, a prediction up to ten-hours ahead more or less becomes possible, and a small-scale cumulonimbus cloud can be expressed, however, this may accompany positional displacement and temporal displacement, thus causing a defect in the reliability of a prediction in any of rainfall predictions related to a dam basin if the prediction is performed singly.SOLUTION: This invention is sourced in the fact that high/low-resolution rainfall prediction waveforms correlated with an actual rainfall amount are correlated with each other. In the method, as indicated in Fig. 10 (linear precipitation band), Fig. 14 (typhoon rainfall), Fig. 20, Fig. 21 and Fig. 22, before an attack of a heavy rain in several hours, a correlation coefficient between an actual rainfall amount and a prediction rainfall amount (indicating the similarity of a rainfall waveform) is large, and the method uses the existence of the correlation. When the high/low (middle) resolution rainfall waveforms are correlated with each other, a value of the correlation (prediction value of a high resolution model) extremely approximates the actual rainfall amount. (Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18 and Fig. 19). Concretely, a level of the correlation of the high/low (middle) resolution waveforms is determined by a waveform correlation coefficient.SELECTED DRAWING: Figure 7
