Problems solved by technology

But there is also a fly in the ointment: the improvement of forecast accuracy is relatively slow, the most representative of the forecast is: the accuracy of 24-hour precipitation weather forecast
[0009] (5) There may be some factors that can cause weather changes in the atmosphere, which have not been discovered so far

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The topography and landforms of various parts of our country are very complex, which have a great influence on weather changes. However, it is very difficult to correct complex terrain conditions and underlying surface properties in the process of numerical prediction calculations. In the calculation process of numerical forecasting: establishment of calculation equations, program design, raw data processing, etc., certain errors will inevitably be brought about in each link. There may be other factors that can cause weather changes in the atmosphere, which have not been discovered so far.

Abstract

The invention belongs to the technical field of weather forecasting, and discloses an intelligent similar weather forecasting method and system, and an information data processing terminal, respectively delimiting similar positions and ranges on historical weather maps; establishing a database, and dividing historical weather maps into months and times , Input at various levels, and carry out intelligent machine identification; after the database is established, test reports are carried out every day; according to the weather map or numerical forecast weather situation map of the day, respectively find out the date with the largest similarity to the history and the weather data of that day; According to the difficulty and ease of finding the similar process and the problems found in the trial report, we will continue to improve. The present invention can skillfully overcome the shortcomings of forecasters' subjective weather forecasting and numerical weather forecasting methods; the present invention can greatly reduce the workload of forecasting duty.

Description

technical field [0001] The invention belongs to the technical field of weather forecasting, and in particular relates to an intelligent similar weather forecasting method and system, and an information data processing terminal. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Before the 1980s, all countries in the world made weather forecasts based on the analysis of weather maps and the experience of forecasters. Its biggest advantage is that various meteorological observation elements are filled on a map according to the location of the station, and each influence weather system: front and back, up and down, left and right, etc. are all clear at a glance, which is convenient for forecasters to carry out comprehensive analysis. However, most of the forecasts made are qualitative (quantitative is difficult). In addition, it is greatly affected by the subjective factors of the forecaster, so it is also called ...
