Precipitation meteorological message data error correction method and glaze landscape prediction method

Abstract

Aiming at a defect that the insufficient consideration to the particularity of a local environment causes a problem that predicted data is liable to have an error in a conventional precipitation prediction method, the invention provides a precipitation meteorological message data error correction method, and the method is used for correcting the precipitation message data Ym, issued by a meteorological station to the public, of a prediction day on a prediction start day, and obtaining a precipitation correction value Yj of the prediction data. The invention also provides a glaze landscape prediction method which is implemented through the above method, and the glaze landscape prediction method is used for predicting on the prediction start day the probability that glaze happens on the prediction day, and correcting a temperature value in the prediction method. The glaze landscape prediction method provided by the invention can be used in a tourism attraction of the Mount Emei. The methods provided by the invention take the meteorological prediction products issued by the meteorological station as the data basis, achieve the prediction of the probability of a meteorological landscape in a given region through the meteorological prediction products issued by the meteorological station, can achieve the effective use of the public service data, and are higher in practicality.

Description

technical field [0001] The invention relates to a method for correcting errors in meteorological forecast values ​​of precipitation and a method for predicting rainy rime landscapes, which belong to the field of meteorological measurement, observation and forecasting. Background technique [0002] The meteorological prediction value of precipitation is obtained by the meteorological department using the global observation network to analyze the observation data using synoptic methods or numerical weather prediction models, and then making corrections with reference to certain elements, and the final forecast conclusions are released to the public through various platforms. To carry out numerical weather prediction of precipitation, it is first necessary to divide the atmospheric space above the surface into many small grids, and use various observation tools to obtain the distribution data of the three-dimensional space of the atmosphere, and then analyze and calculate each g...

Problems solved by technology

However, at present, almost every city above the county level in China has built an automatic meteorological observation station, and each meteorological observation station is responsible for collecting and uploading the meteorological element data in the area. In the scenic area, there is a lack of automatic observation stations with relatively complete functions.
