Weather analysis method and device based on radar echo figure

Abstract

The invention provides a weather analysis method and device based on a radar echo figure, and relates to the technical field of weather forecast. The method comprises the steps of determining a corresponding relation between each piece of radar echo strength information and the occurrence probability of a specified weather type in at least one observation point in advance according to the radar echo strength information and the occurrence of the specified weather type of the at least one observation point at multiple historical moments in a target area; determining the radar echo strength information of the current moment of each observation point in the target area; and using the corresponding relation between each piece of radar echo strength information and the occurrence probability ofthe specified weather type in at least one observation point to determine the occurrence probability of each specified weather type at the current moment in the at least one observation point. According to the method and device provided by the invention, the occurrence probability of the specified weather type can be objectively and quantitatively acquired according to the radar echo figure, meanwhile, the clear and simple weather service is provided for the non-meteorological professionals when relative business decisions are made.

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.
