Abstract

An atmospheric waveguide set forecasting method based on YSU scheme key parameter disturbance comprises the following steps of 1) selecting a regional numerical weather forecasting mode, and setting amode boundary layer parameterization scheme as a YSU scheme; 2) taking a morphological parameter pfac in the YSU boundary layer parameterization scheme as a key parameter, and setting a parameter value range and an interval; 3) calculating the number of members in the set according to the value range and interval of the key parameter pfac; 4) disturbing the key parameter pfac according to the value range and interval of the key parameter pfac, compiling a numerical weather forecast mode for each pfac value, and taking the compiled executable file number as one of the set members; 5) obtainingthe atmospheric waveguide set forecasting mode member based on the key parameter disturbance of the YSU boundary layer scheme after all disturbance members of pfac are compiled, and 6) utilizing theset forecasting mode member obtained in the previous step to carry out atmospheric waveguide simulation and forecasting.

Description

technical field [0001] The invention belongs to the technical field of numerical weather forecasting, and in particular relates to an atmospheric waveguide ensemble forecasting method based on disturbance of key parameters of the YSU boundary layer scheme. Background technique [0002] Atmospheric waveguide is due to the presence of inversion temperature and (or) water vapor in the troposphere with a layer that decreases sharply with height, so that electromagnetic waves form trapping refraction in this layer. The detection of atmospheric ducts mainly depends on high vertical resolution sounding data, such as GPS sounding and low-altitude sounding rocket data. However, these sounding data are released at a single point after all. Although the vertical resolution is better than that of various reanalysis data, the horizontal resolution is still too sparse to fully reproduce the temporal and spatial evolution characteristics of the waveguide. Therefore, the use of mesoscale m...
