Title:
SPATIAL PROBABILITY ANALYSIS METHOD AND SYSTEM BASED ON CORRESPONDENCE BETWEEN PRECIPITATION FORECAST AND TELECONNECTION
Document Type and Number:
WIPO Patent Application WO/2023/240509
Kind Code:
A1
Abstract:
A spatial probability analysis method and system based on a correspondence between a precipitation forecast and teleconnection, which method and system relate to the technical field of precipitation forecast analysis. The method comprises the following steps: acquiring a sample sequence of precipitation forecasts to be analyzed, and sample sequences of corresponding observed precipitation and meteorological factors (S1); according to the acquired sample sequences, separately calculating a forecast-observation correlation coefficient and a meteorological factor-observed precipitation teleconnection coefficient of each grid, and classifying each grid according to the saliency of the forecast-observation correlation coefficient and the meteorological factor-observed precipitation teleconnection coefficient (S2); according to the grid classification result, determining a correspondence between the forecast-observation correlation coefficient and the teleconnection coefficient (S3); calculating a spatial weight coefficient according to the spatial coordinates of each grid, so as to obtain a spatial weight coefficient matrix (S4); and according to the spatial weight coefficient matrix and the correspondence between the forecast-observation correlation coefficient and the teleconnection coefficient, calculating the spatial consistency probability of the forecast-observation correlation coefficient being in a significant positive correlation (S5).
