In the past, the analysis in the aspect of rainfall focuses on the analysis of rainfall intensity, rainfall frequency, rainfall period, rainfall trend, rainfall mutation and the like, the most concentrated part of the rainfall intensity of a region is considered a little, the position of the precipitation concentration in the region can be clearly known through the research on the regional rainfall center, and the spatial and temporal distribution rule and the evolution characteristic of regional rainfall can be qualitatively and quantitatively mastered through the analysis on the transfer tracks of the rainfall center in the historical period and the current period, so that reference information can be provided for relevant departments such as flood control, drought control and the like, and theoretical basis and technical support can be provided for the flood control and the disaster reduction of the region.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Aiming at the problems that the existing precipitation center is inaccurate to determine and is not beneficial to analyzing regional precipitation characteristics, the method, the device and the electronic equipment for determining the precipitation center position and the change of the precipitation center position can accurately determine the precipitation center position of a precipitation region so as to effectively analyze the regional precipitation characteristics based on the position change of the precipitation center position.

The embodiment provides a method for determining a precipitation center position and a precipitation center change, wherein, referring to a flowchart of a method for determining a precipitation center position and a precipitation center change shown in fig. 1, the method specifically includes the following steps:

step S102, carrying out Thiessen polygon division on a precipitation area to be researched based on the position distribution of precipitation sites to obtain a plurality of Thiessen polygon areas;

based on the principle that each thieson polygon area only includes one precipitation site, thieson polygon division is performed on the precipitation area to be researched, for convenience of understanding, fig. 2 shows a schematic diagram of a thieson polygon division mesh, as shown in fig. 2, the thieson polygon area is an irregular polygon, and black dots represent precipitation sites.

Step S104, calculating precipitation intensity corresponding to each specified time period which is divided in advance by each Thiessen polygon area according to the research time scale; wherein the research time scale is year, flood and dry season, month or day;

for example, with 70 years as the total time period, if the research time scale is years, 70 years can be divided into 7 designated time periods on average, and the duration of each designated time period is 10 years.

If 70 years are divided according to the time period between two raining sessions, the time interval of the two raining sessions is different, so the time length of each divided designated time period may be different, for example, the first rainfall session is 2015 years, 5 months and 15 months, the second rainfall session is 2016 years, 6 months and 15 months, and the third rainfall session is 2016 years, 9 months and 15 months, wherein the time length of the designated time period corresponding to the first rainfall session and the second rainfall session is 13 months, and the time length of the designated time period corresponding to the second rainfall session and the third rainfall session is 3 months.

In this embodiment, the precipitation intensity may be represented by precipitation amount, and the calculation process of the specific precipitation intensity is as follows: counting the total precipitation of each Thiessen polygon area in each designated time period; the precipitation amount sum is determined as the precipitation intensity of each Thiessen polygon area for each specified period.

For example, with 70 years 1951-2020 as a research time scale, 7 specified time periods are divided in advance as follows: 1951-1960, 1961-1970, 1971-1980, 1981-1990, 1991-2000, 2001-2010, 2011-2020, wherein the duration of the specified time interval is 10 years, and for each Thiessen polygon area, the total amount of precipitation during each 10 years needs to be counted to obtain the precipitation intensity of the Thiessen polygon area for each specified time interval.

For ease of understanding, fig. 3 shows a schematic representation of precipitation intensity, as shown in fig. 3, the darker the grey scale indicates the greater the precipitation intensity, i.e., the greater the precipitation; the display of the precipitation intensity and the color can be set according to actual needs, for example, the precipitation intensity is 9091mm-10000mm, the corresponding color is light gray, the precipitation intensity is 100001mm-15000mm is gray, and the precipitation intensity is 150001mm-25000mm is dark gray, so that the display of the precipitation intensity color is not limited here.

Step S106, calculating the precipitation central position of the precipitation area to be researched aiming at each appointed time period based on the precipitation intensity of each appointed time period corresponding to each Thiessen polygon area;

the above step S106 can be realized by the steps a1 to a 2:

step A1, calculating the centroid point position and the area of each Thiessen polygon area;

in the present embodiment, the centroid point position is calculated by the following formula:

wherein the content of the first and second substances,an abscissa representing the centroid point position of the ith Thiessen polygon area,and x and y respectively represent an abscissa value and an ordinate value.

For ease of understanding, fig. 4 shows a schematic diagram of centroid positions, as shown in fig. 4, the centroid positions of the respective thiessen polygon areas for a certain specified period are represented by black dots, the black dots in fig. 4 represent the centroid positions, and the black dots in fig. 2 are different from the black dots in fig. 4 to represent precipitation sites.

Since the above-described thiessen polygon region is an irregular polygon, the region area of the thiessen polygon region may be calculated by a method such as an addition method, a subtraction method, a direct finding method, or an auxiliary line method, and is not limited herein.

Step A2, calculating the precipitation center position of the precipitation area to be researched for each appointed time period based on the centroid position and the area of each Thiessen polygon area and the precipitation intensity of each appointed time period corresponding to each Thiessen polygon area.

The precipitation center position is calculated by:

wherein the content of the first and second substances,is the abscissa of the precipitation center position of the nth specified time period of the precipitation area to be researched,ordinate, p, of the position of the centre of precipitation for the nth specified period of the precipitation zone to be studied_i,nFor the intensity of precipitation in the ith Thiessen polygonal area of the nth specified period, A_iIs the area of the ith Thiessen polygon area.

And S108, determining the position change of the precipitation center position of the precipitation area to be researched according to the precipitation center position corresponding to each appointed time period.

Through the step S106, the position coordinates of the precipitation central position of the precipitation area to be researched in each appointed time period can be obtained, and the change conditions of the precipitation central position in different appointed time periods can be quantitatively described through the position change of the position coordinates of the precipitation central position of the precipitation area to be researched corresponding to two adjacent appointed time periods.

This change in position can be calculated by:

wherein the content of the first and second substances,andposition coordinates representing the precipitation centre position of the precipitation zone to be studied for the (n + 1) th and the (n) th specified time period, respectively.
