“…In the past three years, especially in 2021 and 2023, however, the frequent occurrence of spring SDSs in East Asia has attracted increased interest among the scientific community [8][9][10]. The 10 spring SDSs affecting Northern China in 2021-2023 all originated from Mongolia (see last three rows of Table 1).…”

“…It is clear that the vast majority of cross-border SDSs (86.8%) were related to MCs during this period, consistent with the fact that mid-latitude weather disturbances over the Mongolian Plateau are most active in spring. When weather disturbances extended over the western mountains of the Mongolian Plateau, MCs easily form and develop [8,37], thus triggering SDSs under the condition of sufficient sand and dust sources. In addition, the MC-CH type is also a very important weather system driving cross-border SDSs and has become very active in recent years (2021-2023), which may be related to the enhancement of the mid-latitude baroclinic wave amplitudes [8].…”

In addition, the MC-CH type is also a very important weather system driving cross-border SDSs and has become very active in recent years (2021-2023), which may be related to the enhancement of the mid-latitude baroclinic wave amplitudes [8]. We examined two types of MCs, the MC-dominant type and MC-CH type, in terms of the genesis location, movement path, and peak amplitude position, as shown in Figure 5.…”

“…For example, the cross-border SDS that occurred on 14-17 March 2021 was the strongest in the present decade in Northern China. This strong cross-border SDS was triggered and driven by a strong Mongolian cyclone (MC) and affected Northwestern, Northern, and Northeastern China [8]. The instantaneous wind speed during this SDS reached 40 ms −1 in Inner Mongolia, and the PM10 concentration reached 9753 µg/m 3 in Beijing [9,10].…”

Sand and dust storms (SDSs) are particularly concerning natural disasters in East Asia. At present, there is still a lack of comprehensive knowledge of the characteristics of the cross-border SDSs between Mongolia and Northern China and the associated weather systems. This study identifies and documents the spring cross-border SDSs between Mongolia and Northern China based on the MODIS AOD map and Himawari-8/9 dust RGB images and analyzes the corresponding weather system types. A total of 76 spring cross-border SDSs were identified during 2000–2023, accounting for 55.1% of the total SDSs in both countries. The vast majority of the cross-border SDSs (86.8%) were related to Mongolian cyclones (MCs). Among them, 53.9% of the cross-border SDSs were mainly driven by Mongolian cyclones alone, and 32.9% were driven by the combination of MCs and cold highs (MC-CH type). Significant differences in the horizontal distribution of the SDSs were observed for different weather types. MCs alone trigger SDSs in the southern halves of the MCs, so the horizontal extent of the SDSs is consistent with that of MCs but larger than that associated with cold fronts. For the MC-CH type, strong winds in the southern flanks of MCs and their rear cold highs jointly drive a large-scale zonally extensive SDS belt. In recent years, particularly in 2021 and 2023, the strong cross-border SDSs have been dominated by the MC–CH type. This study provides a reference for the forecasting and early identification of cross-border SDS disasters.

“…We believe that due to the complexity of various circulation situations, it is not enough to judge classification solely based on experience. In recent years, dust storms caused by Mongolian cyclones occur frequently (Bueh et al, 2022; Yin et al, 2022). In order to meet the demand for accurate prediction of Mongolian cyclones, it is necessary to use more objective methods to classify the moving paths of spring Mongolian cyclones.…”

Based on the fifth‐generation reanalysis (ERA5) data of the European Centre for Medium Range Weather Forecasts (ECMWF), spring Mongolian cyclones were examined from 1950 to 2023. Then, based on the feature parameters of activity path information, machine learning method (k‐means) is used to classify the trajectories of spring Mongolian cyclone. Subsequently, the atmospheric circulation configurations of the three categories of Mongolian cyclones and their influence on the weather in China verify the reasonability of the classification method. Specifically: (1) eastward moving type, affecting Inner Mongolia and Northeast China (Clus‐1). The circulation background of the Clus‐1 cyclone displays a broad negative geopotential height anomaly centre over East Asia; (2) northeastward moving type, affecting northeast part of Northeast China (Clus‐2). The circulation background of the Clus‐2 cyclones shows a “positive–negative–positive” distribution of circulation anomalies in the European Plain, Lake Baikal and the Sea of Japan; (3) southeastward moving type, this type can move to the south of China (Clus‐3). The circulation background of the Clus‐3 cyclones is opposite to that of the Clus‐2 cyclones. The three categories of Mongolian cyclones will cause dust weather and strong winds in different regions of China, mainly affecting Inner Mongolia and Northeast China.
