Meteorological thunderstorm day is with weather station data for Statistic Source when adding up, and for Shanghai City, for the whole city, has 11 independent observation statisticss.Lightning monitoring and positioning system are different from weather station, and in overlay area, the data source of its monitoring is continuous, non-separation, and gridding method therefore can be adopted to add up thunderstorm day.
Gridding method carries out equal area partition to selection area, as 0.1 ° × 0.1 ° (about corresponding 10km × 11km), namely each grid is a thunder and lightning measuring unit, the same weather station of statistical method: each grid occurs a thunder and lightning every day, is grid thunderstorm day.Add up grid thunderstorm day in year of each grid, and selection area year grid is got average thunderstorm day, draw this region annual thunderstorm day.
Selected sizing grid is the key of lattice statistical method, may hear that (be commonly considered as about 5 ~ 25km around lightning, namely area is 25 ~ 625km for the scope of thunder with reference to the people of conventional ground weather station 2), the corresponding grid of table 1 can be selected and analyze.Table 1 is different grid resolution, area, Shanghai City grid number information slip.

District of Shanghai grid obtains example thunderstorm day
Meteorological thunderstorm day and grid comparative analysis in thunderstorm day
Add up by the grid of definition description 2003 ~ 2008 6 years measurement data, and list file names with maximal value and the mean value in the meteorological thunderstorm day in year of identical period, correlated results is in table 2.Table 2 gives the statistical value in thunderstorm day in year that Shanghai City obtains with 0.05 ° ~ 0.275 ° lattice statistical for 2003 ~ 2008 years 8 years.Statistics shows the thunderstorm earning in a day and the positive correlation of grid area, and this is readily appreciated that: grid is large, and thunderstorm occurs that chance is many, and have the grid of thunderstorm many, total grid number is few, therefore average is large.
Table 2
Note: Max is maximal value; Mean is average,
Because observation procedure is completely different with data source distribution, network technique statistical value can not complete corresponding meteorological statistics value.In general, 0.15 ° of lattice statistical mean value is closest with mean value in meteorological thunderstorm day, and its deviation is 10%, and only Chongming and Kingsoft comparison value deviation are comparatively large, and rejecting its deviation behind Chongming and Kingsoft is 6.5%; Other lattice statistical mean value is as follows with mean deviation in meteorological thunderstorm day: 0.175 ° of grid is 17%, 0.2 ° of grid be 18%, 0.25 ° of grid be 38%, 0.275 ° of grid is 56%.0.275 ° of lattice statistical maximal value is closest with meteorology maximal value in thunderstorm day, its deviation is 7%, other lattice statistical mean value and meteorological thunderstorm maximal value deviation as follows: 0.15 ° of grid is 35%, 0.175 ° of grid is 27%, 0.2 ° of grid is 23%, 0.25 ° of grid is 10%.
Grid computation model in thunderstorm day
Can be obtained by above-mentioned analysis, 0.15 ° of lattice statistical mean value can be used for annual thunderstorm day based on the lightning monitoring of District of Shanghai and positioning system, its value mean deviation compared with meteorological statistics data is about 10%.Consider stress and strain model, 0.275 ° of lattice statistical maximal value can be used for maximum thunderstorm day in year, its value is on average partially about poor compared with meteorological statistics data is 7%.
Other time grid exports and display thunderstorm day
According to District of Shanghai obtained above grid definition in thunderstorm day and analysis module, the grid thunderstorm day in other year can be obtained based on lightning monitoring and positioning system, Geographic Information System (GIS) calculating and output module.2009 to 2011 years maximum, average meshes is as shown in table 3 below for thunderstorm day.
