Consider the following statements regarding the northeast (retreating) monsoon over peninsular India and the factors that modulate its rainfall activity:

Statements

1. The northeast monsoon season over peninsular India spans October to December, with October typically contributing the major share of seasonal rainfall in states like Kerala.
2. The Madden-Julian Oscillation (MJO) in a suppressed phase over the Bay of Bengal region tends to inhibit cyclogenesis and reduce rainfall activity during the northeast monsoon season.
3. The northeast monsoon draws its primary moisture from the Arabian Sea, and weakening of Arabian Sea branch winds is the dominant factor in reducing rainfall over Kerala during this season.
