Rationality Analysis of Artificial Precipitation Enhancement Area in Bayanbulak Mountainous Area in Warm Seasons
Based on the daily meteorological data from 18 observation stations in the Bayanbulak mountainous areas from May to September during 2017-2022,the spatial distributions of precipitation characteristics were analyzed with the Collaborative Kriging(Co-Kriging)method and K-Means clustering grouping method.the rationality of the layout of manual water addition operations were discussed at a macro level.The results showed that:(1)The small rain had the highest interpolation accuracy and the smallest relative error,while heavy rainstorm was opposite,leading to a significant"smoothing effect"and greater uncertainty in the spatial interpolation.(2)In the warm season,the average monthly precipitation decreased from west to east,with high values mostly locating in the central and northeastern mountainous areas,and the rainfall events were mainly characterized by small rain,although heavy rainstorm had a low probability,it was still a major factor affecting the variation in precipitation.(3)Affected by the occurrence probabilities of small rain and moderate rain on the spatial distribution,the suitability of the current artificial precipitation enhancement operation points were mostly generality,and the western region was higher than that of the eastern region in terms of macro geography.(4)The spatial distributions of precipitation were greatly influenced by the westerly circulation and topography,therefore,the rationality of operational layout was higher in the western and northern regions.(5)Based on geographical and wind direction characteristics,the northern region with complex topography,was suitable to establish ground smoke furnaces with a west-low-east-high orientation,and the western region with flat terrain,was suitable to establish mobile rockets with an NNW or ENE operating direction.
