Weather analysis method and device based on radar echo chart

Abstract

The present invention provides a weather analysis method and device based on radar echo charts, and relates to the technical field of weather forecasting. and the occurrence of the specified weather type, determine the corresponding relationship between the radar echo intensity information of each of the at least one observation point and the occurrence probability of the specified weather type; determine the radar echo intensity information of each observation point in the target area at the current moment; apply The corresponding relationship between the intensity information of each radar echo in at least one observation point and the occurrence probability of the specified weather type determines the occurrence probability of the specified weather type at each current moment in at least one observation point; the present invention can obtain according to the radar echo chart Obtain the occurrence probability of the specified weather type objectively and quantitatively, and provide clearer and simpler meteorological services for non-meteorological professionals when making related business decisions.

Description

technical field [0001] The invention relates to the technical field of weather forecasting, in particular to a weather analysis method and device based on radar echo charts. Background technique [0002] At present, the application of domestic radar echo charts in weather forecasting business is mainly based on the analysis of radar echo charts, and echo images are mainly based on the different intensities of echoes displayed in different colors. For forecasters, the display mode of this image is that the weather information such as cloud precipitation and thunderstorm contained in the radar echo map is only a quasi-qualitative analysis, and cannot objectively and quantitatively display the temporal and spatial distribution of precipitation, thunderstorm and other weather. The utilization efficiency of the information in the graph is low. It is difficult for non-professionals to understand the distribution of radar echo images, and it is also difficult for forecasters witho...

For forecasters, the display mode of this image is that the weather information such as cloud precipitation and thunderstorm contained in the radar echo map is only a quasi-qualitative analysis, and cannot objectively and quantitatively display the temporal and spatial distribution of precipitation, thunderstorm and other weather. The utilization efficiency of information in the graph is low

It is difficult for non-professionals to understand the distribution of radar echo images, and it is also difficult for forecasters without relevant technical training to accurately analyze the structure and change characteristics of radar echo images.
