Explanation
The onset of the southwest monsoon in India follows a specific geographical sequence. It typically 'bursts' on the Malabar Coast in Kerala by June 1 [3]. Following this, the Bay of Bengal branch advances rapidly, reaching West Bengal (Kolkata) around June 5 to June 10. As the monsoon currents merge and move across the Gangetic Plain, they reach Uttar Pradesh by mid-June (approximately June 15 to June 20) [2]. Finally, the monsoon reaches the western parts of the country, arriving in Rajasthan by the first week of July, with the Thar Desert being the last region to receive it by mid-July [2]. Therefore, the ascending order of onset dates is Kerala (June 1), West Bengal (early June), Uttar Pradesh (mid-June), and Rajasthan (July), which corresponds to the sequence 3-2-1-4.
