Pre-monsoon dust storms also known as “Andhi” are one of the common phenomena occurring over the northern part of Indian sub-continent. Using the synergetic information from multiple platforms, the life cycle of an infamous dust storm event has been investigated, which impacted the urban megacity of New Delhi on May 30, 2014. The analysis from the radar revealed that the storm resulted from the merger of the outflow boundaries of two propagating thunderstorms in the mesoscale vicinity of New Delhi region. The leading edge of the outflow of downdraft cold air generated from the storm, ploughs the loose hot soil from the surface, thereby resulting to the severe dust storm over the region. Along with the heavy aerosol loading on that day as found from the satellite data, the evolution of the storm was also associated with sudden change in surface meteorological parameters which are manifested through the increase in near surface humidity (~ 70%) and pollution levels along with the decrease in surface temperature (−12%). Although the study is centered at one event, the inferences distilled from this study are beneficial for the improvement of the predictive capability of severe weather events particularly for the tropical countries.

季风前的沙尘暴也被称为“安迪”，是印度次大陆北部普遍发生的现象之一。利用来自多个平台的协同信息，调查了一次臭名昭著的沙尘暴事件的生命周期，该事件于2014年5月30日影响了新德里的城市特大城市。新德里中尺度附近两次传播性雷暴的流出边界。暴风雨产生的向下流动的冷空气流出的前缘将地表松散的热土壤犁开，从而导致该地区出现严重的沙尘暴。以及当天从卫星数据中发现的大量气溶胶负载，风暴的演变还与地表气象参数的突然变化有关，这通过近地表湿度的增加（约70％）和污染水平以及地表温度的下降（​​-12％）来体现。尽管该研究集中在一个事件上，但从该研究中得出的推论对于提高恶劣天气事件的预​​测能力特别是对热带国家而言是有益的。
