3. Show rainfall in the form of rainfall contours and isosurfaces (mainly based on measured rainfall or forecasted rainfall, without comprehensive consideration of measured rainfall and forecasted rainfall)
[0005] The drawing of rainfall contours and isosurfaces in the current flood control information system is mostly based on the actual measured rainfall. Flood control staff can only understand the current distribution of rainfall in different regions through contours and isosurfaces. For the deployment of flood control work, the time to prepare for an emergency is relatively short

Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0016] A isoline, isosurface drawing, and early warning method based on measured and forecasted rainfall, which includes the following steps: Step S1: Obtain future forecasted rainfall data and current measured rainfall data; Step S2: Obtain The future forecasted rainfall and measured rainfall data are processed according to the set rules, and the processed data is called forecasted rainfall, which is output to the isoline, isosurface drawing module and early warning judgment module; step S3: the forecasted rainfall data Draw isolines and isosurfaces of rainfall; early warning thresholds are set for each time period, and the forecasted rainfall is compared with the early warning thresholds of the corresponding time period. The rainfall and the time period information corresponding to the rainfall are transmitted to the early warning release mod...

Abstract

The invention provides an isoline and isosurface drawing and early warning method based on practical measurement and forecasted rainfall quantity. Meanwhile, the forecasted rainfall isoline and isosurface drawing can be performed by considering the existing practically measured rainfall quantity and the future forecasted rainfall quantity; the forecasted rainfall quantity and the practically measured rainfall quantity are obtained; data of the forecasted rainfall quantity and the practically measured rainfall quantity is processed; the rainfall isoline and isosurface are drawn according to the treated forecasted rainfall quantity; therefore regions to be focally concerned in future can be directly known through the treated forecasted rainfall quantity isoline and isosurface; the emergency preparation time can be greatly brought forward. Further, early warning can be given out in advance on the basis of the comparison of the treated forecasted rainfall quantity with the measured station early warning threshold value, so that relevant responsible persons can take note of the regions possibly generating the dangerous conditions; the dealing measures can be taken in advance.

Description

technical field [0001] The invention belongs to the field of weather forecasting and early warning, and in particular relates to a method for drawing isolines and isosurfaces and early warning based on measured and forecasted rainfall. Background technique [0002] The existing flood control informatization-related systems mainly display the rainfall in the following ways: 1. Display the rainfall in the form of text or table. 2. Display the rainfall in the form of a rainfall histogram. 3. Show rainfall in the form of isolines and isosurfaces (mainly drawn based on measured rainfall or forecasted rainfall, without comprehensive consideration of measured and forecasted rainfall). [0003] The early warning methods based on rainfall mainly include: 1. The measured rainfall is compared with the early warning threshold, and an early warning is issued when the threshold is reached. 2. The forecast rainfall is compared with the warning threshold, and the warning will be issued wh...
