Problems solved by technology

[0002] When forecasting, forecasters often consider what kind of weather and distribution conditions this weather situation can cause, and look for similar weather situations as a reference, but traditional meteorological data is very inconvenient
First of all, meteorological data is stored every day, and the quantity is too large to be easily searched.

Embodiment Construction

[0028] Below in conjunction with specific embodiment, technical solution of the present invention is described in further detail:

[0029] Weather forecasting method of the present invention mainly comprises the following steps:

[0030] Step 1, import historical meteorological data, extract the water vapor condition, thermal energy condition, and dynamic condition data in the meteorological data, and calculate the meteorological specific humidity, pseudo-equivalent temperature and vertical velocity of different longitudes, latitudes and dates respectively, and according to the longitude, latitude and date order storage;

[0031] Step 2, for the area of ​​concern of the forecaster, according to the current meteorological data, respectively calculate the average value of the specific humidity, false equivalent potential temperature and vertical velocity in the current area;

[0032] Step 3, for the forecaster's attention area, according to the specific humidity, false equivale...

Abstract

The invention discloses a method and device for weather forecasting, which extracts and draws various physical quantities of the weather system according to the weather data set, objectively provides the characteristics between factors of the historical weather system, and checks and retrieves them through the similarity retrieval function Historical meteorological data with similar date water vapor conditions, thermal energy conditions or dynamic conditions, and display the future water vapor conditions, thermal energy conditions or dynamic conditions of historical meteorological data for forecasters to use as a forecast reference to improve the modernization level of meteorological research.

Description

technical field [0001] The invention relates to a weather forecasting method and device, belonging to the field of weather forecasting. Background technique [0002] When making forecasts, forecasters often consider what kind of weather and distribution conditions this weather situation can cause, and look for similar weather situations as a reference. However, it is very inconvenient to consult traditional meteorological data. First of all, meteorological data is stored every day, and the amount is too large to be easily searched. Secondly, even if the weather data of a certain time is found, it is necessary to use third-party software to display it as a graph, and then subjectively review and compare the weather situation of the day, and finally judge whether the weather data of that time is of reference value. Contents of the invention [0003] Aiming at the defects of the background technology, the present invention provides a weather forecasting method and device, wh...
