Statement-I: The northeast monsoon rain has increased by more than 10% in the past decade (2012-2022) in several areas of Tamil Nadu, Telangana, and Andhra Pradesh.
Statement-II: The Bay of Bengal has witnessed formation of more frequent low-pressure systems and depressions during the northeast monsoon months.
Which one of the following is correct in respect of the above statements? 
Explanation –
Statement-I is correct, as several areas in Tamil Nadu, Telangana, and Andhra Pradesh have witnessed an increase in northeast monsoon rain of more than 10% in the past decade. This trend has been observed in cities like Chennai, Hyderabad, and Vishakhapatnam.
Statement-II is also correct, as the Bay of Bengal has seen an increase in the frequency of low-pressure systems and depressions during the northeast monsoon months (October to December). These weather systems are responsible for bringing rainfall to the regions of Tamil Nadu, Telangana, and Andhra Pradesh, and their increased frequency could explain the rise in northeast monsoon rain in the affected areas.
Therefore, Statement-II provides an explanation for the trend observed in Statement-I, and both statements are correct.
