The Indian Summer Monsoon typically begins over Northeast India (NEI) about 2 weeks earlier than monsoon onset over Kerala, extending the rainy season in NEI to around 150 days. This early onset is strongly linked to planetary‐scale processes, particularly interactions with extratropical Rossby waves. These waves facilitate the downward and southward intrusion of potential vorticity, which triggers low‐level cyclonic vorticity...

In Assam, local severe convective storms (LSCS) are recognized as exceptionally powerful and destructive meteorological events resulting in both death and loss of property, as well as livelihood. A valuable aid to assessing and managing LSCS lies in a reliable database of historical severe storms. In this paper, we investigate the temporal and spatial characteristics of LSCS in the state of Assam lying in the North Eastern Pro...

In operational meteorology, forecasting heavy rainfall (HRF) events has been a long‐standing challenge in India. This is especially true in certain regions where the physical geography lends itself to the creation of such HRF events. Northeast India (NEI) is one such region within the Asian monsoon zone, which receive very HRF during the pre‐monsoon and summer monsoon season and the summer–autumn transition month of October. T...
