Principle of forest and grassland fire danger weather grade forecast system.

Establish information configuration table of meteorological monitoring points, including input data worksheet name, output data worksheet name, input data number, whether dew point temperature is input, humidity output type, monitoring point elevation, annual average rainfall value of monitoring point, monitoring data time, monitoring point maximum temperature, monitoring point minimum temperature, monitoring point rainfall and monitoring point dew point temperature.

Then the EXCEL table of input data is established, with one data in each row, including latitude and longitude, altitude, slope, slope direction, isohyet and other information. The input file is based on the second-class data and DEM data, which is obtained through spatial analysis and calculation. Latitude and longitude information is obtained by calculating central coordinates, and altitude, slope and aspect information is obtained by calculating regional average value by applying boundary and DEM data.

Finally, write a program, call the temperature and humidity calculation function in MTCLIM model, calculate the temperature and humidity information to be predicted, and output it to EXCEL, so as to realize the unified calculation of temperature and humidity information.

Attention.

Forest fire risk is divided into five grades. The higher the grade, the greater the possibility of fire. The meaning of each level is as follows:

The first level is safe and not easy to burn. General preventive measures can be taken to prevent man-made fires.

The second grade is difficult to burn, and the fire risk is low. Please pay attention to the safety of using fire in the wild.

Third-class flammable, meteorological conditions can cause fire. Please control the use of fire in forest areas and scenic spots.

Class IV flammable, prone to fire. Forest areas and scenic spots should strictly control the use of fire in the wild.

The fifth level is the alarm level, which is easy to cause forest fires. Forest areas and scenic spots should prohibit all outdoor use of fire.
