5 Coding Rules
5.1 General
n, n. Lar Lr LarLar Le Lo Lor LorS. S, S, S, S.5.1.1A 5.1.2 Part C and Part D shall report the detection data of each layer above 100hPa. QX/T120—2010
5.1.3 Using sounding balloon When wind measurement, radio theodolite wind measurement or radar wind measurement is used and sounding report is compiled, only Part B and Part D of the wind measurement report may be compiled, and Part A and Part C may be omitted. When reporting wind forecasts, Part A, Part B, Part C and Part D should be compiled and reported. 5.1.4 Rules for Reporting Missing Tests
The format for reporting missing tests is as follows:
HiiiNIL
Partial Identification Group
NIL is a fixed code: used for Indicates missing data report. When all the data required to be reported by a department are missing, a missing data report of that department should be reported. When all the data of a certain wind measurement are missing due to some reason, a missing data report of Department A, Department B, and Department C should be reported at the same time. 5.2 Coding rules for Part A and Part C
5.2.1 Paragraph 1
5.2.1.1 This paragraph shall include the wind measurement department identification group, time group and measurement group. 5.2.1.2PPAA and PPCC are the identification groups of Part A and Part C of the wind report respectively. 5.2.1.3lliii is the area station number, indicating the location of the station. 5.2.2 Second paragraph
5.2.2.1 This paragraph compiles and reports the wind detection data of the specified isobaric surface layer, and compiles and reports it in order from bottom to top according to the layer height. Specifically: a) Part A compiles and reports The prescribed isobaric surface layers are: 850hPa, 700hPa, 500hPa, 400hPa, 300hPa, 250hPa, 200hPa, 150hPa, 100hPa.
b) The prescribed isobaric surface layers reported in Part C are: 70hPa, 50hPa, 30hPa, 20hPa, 10hPa, 7hPa, 5hPa, 3hPa, 2hPa, 1hPa. Among them, 7hPa, 5hPa, 3hPa, 2hPa, and 1hPa are reported only when there is detection. 5.2.2.2 The indicator code of this section is "55", indicating that the data group reports the wind data at the average height of the specified isobaric surface layer. 5.2.2.3 All specified isobaric surface layers within the detection range should be reported. For specified isobaric surface layers with wind data, report the wind data group; for specified isobaric surface layers without wind data, report the wind data group as “/ ////". 5.2.2.4 55nP, P1 group can be reported repeatedly. After each 55nP, P group, up to three consecutive detection data of the specified isobaric surface layer can be reported.
5.2. 3 The third paragraph
5.2.3.1 This paragraph compiles and reports the maximum wind layer detection data and wind vertical shear data 5.2.3.2 When more than one maximum wind layer is detected, the data in this section can be repeatedly reported in the order of wind speed from large to small. When the wind speeds of the maximum wind layers are equal, they are reported in the order of appearance height from bottom to top. 5.2.3.3 The rules for using indicator codes are as follows:
a) When the maximum wind layer appears in a closed high wind area, this section uses \7” as the indicator code, that is, 7HHmHmdmdmffmfm is reported; when the maximum wind layer appears in a non-closed high wind area, this section uses \6” as the indicator code, that is, 6H.H.HHmd.dfffm is reported. Note: When both the beginning and end of a high wind area are detected, it is called a closed high wind area. When only the beginning of a high wind area is detected, but the end is not detected, it is called a non-closed high wind area.
b) When the maximum wind layer is not detected, this section is reported as "77999". 5.2.3.4 Wind vertical shear data group 4v.VsV.V is optional data and may not be reported. 5.2.4 Sixth paragraph
QX/T120—2010
5.2.4.1 This paragraph reports the positioning data of the isobaric surface layer and the maximum wind layer detection data, including: time positioning data and space positioning data. Among them, the time positioning data is reported in relative time; the space positioning data is reported in relative longitude and latitude. 5.2.4.2 The ground layer only reports the relative time, not the relative longitude and latitude. 5.2.4.3 Except for the ground layer, other specified isobaric surface layers should report the relative time and relative longitude and latitude. 5.2.4.4 The maximum wind layer reports the relative time and relative longitude and latitude. When the third paragraph code is "77999", the maximum wind layer positioning data group (including the indicator code "63636") is not reported.
5.3 Coding rules for Part B and Part D
5.3.1 The first paragraph
5.3.1.1 This paragraph compiles the identification group, time group and station area number of the wind measurement report. 5.3.1.2PPBB and PPDD are the identification groups of Part B and Part D of the wind measurement report respectively. 5.3.1.3IIiii is the area number, indicating the location of the station. 5.3.2 The fourth paragraph
5.3.2.1 This paragraph compiles the wind detection data of the specified altitude layer and/or characteristic layer, and compiles it in order from bottom to top according to the layer height. 5.3.2.2 When "8" is used as the indicator code, the height of the specified altitude layer reported is in units of 500m, and the first u1 should be reported as \/", to indicate that the first wind data group reports the station layer data. The reporting rules for missing data are as follows:
a) In Part B and Part D, the height is reported in terms of geopotential height, and when the thickness of the missing layer is above 1500gpm (geopotential meter), the detection data of the upper and lower boundaries of the layer should be reported, and a height between the upper and lower boundaries should be reported. The value and “/////” are used to indicate the layer where the data is missing. The upper and lower boundaries refer to the two layers closest to the top and bottom of the data missing layer and with detection data, which may not meet the standard of the characteristic layer.
b) In Part B and Part D, when the altitude is reported in terms of pressure and the thickness of the data missing layer is above 50hPa, the detection data of the upper and lower boundaries of the layer should be reported, and the data missing layer should be indicated by “/////”. The upper and lower boundaries refer to the two layers closest to the top and bottom of the data missing layer and with detection data, which may not meet the standard of the characteristic layer. The data group of the data missing layer and its upper and lower boundaries is identified by the nn value. 5.3.3 Paragraph 6 - Time and Space Positioning Data
5.3.3.1 This paragraph reports the time positioning data and space positioning data of the detection data of the specified altitude layer and/or characteristic layer. 5.3.3.2 Only relative time is reported for the ground layer, and relative longitude and latitude are not reported. 5.3.3.3 Relative time and relative longitude and latitude are reported for the specified altitude layer and/or characteristic layer. 6 Paragraphs Coding method
