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.

Embodiment 1

[0069] The precipitation meteorological station forecast value at 08 o'clock on March 13, 2017 in the Mount Emei scenic spot in Sichuan Province was corrected with the method for correcting the data error of the precipitation meteorological message of the present invention.

[0070] Group 1: Starting time 2017031220, forecast 2017031308~20170313020

[0071] The starting time of the report is 2017031220 (20:00 on March 12, 2017, the same below), and the forecast period is 2017031308 to 20170313020 (daytime on March 13, 2017), so the forecast time limit is 012 to 024 hours.

[0072] Step S1. Obtain the forecasted daily precipitation report data Y m

[0073] Precipitation report data Y m It is the forecast date issued by the Meteorological Observatory on March 12, 2017 at 20:00 (that is, the start time A) for the forecast period of March 13, 2017 from 08:00 to 20:00 (daytime). text data.

[0074] Step S2. Determine the rainy and sunny thresholds TH for each forecast timelines...

Embodiment 2

[0095] The rime landscape prediction method of the present invention is used to measure and calculate the occurrence probability M of the rime landscape on March 13, 2017 and April 19, 2017, respectively, in Mount Emei, Sichuan Province.

[0096] Group 1: Initial report 2017031220, forecast 20170313

[0097] Step S1: Judging the occurrence probability M of rime landscape according to the time period

[0098] Step S11, determine the occurrence time period of the rime landscape

[0099] According to the recorded data of rime landscape in Mount Emei Scenic Area in the past 5 years, statistics determine that the occurrence time period of rime landscape in Emei Mountain Scenic Area is January, February, March, April, October, November, and December.

[0100] Step S12, judging the occurrence probability M of rime landscape according to the time period

[0101] The forecast date is March 13, 2017, which belongs to the time period r, and proceeds to step S2.

[0102] Step S2, deter...

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...
