The annual monsoon rains are vital for India because around 80 percent of the country's rainfall occurs during monsoon season. While the torrential rains can be a headache and cause flooding and other issues, they are vital for providing the moisture the country's agricultural system needs to raise crops. Monsoon rains also replenish lakes and underground aquifers, creating a storehouse of water to see India through its nine dry months.
Indian agriculture makes up around 18 percent of the country's economy, and employs more than half of the population. For this reason, the monsoon is possibly the most vital meteorological event that happens in India every year. Unfortunately, the monsoon pattern is susceptible to disruption by other ocean conditions like El Ninos and La Ninas. This can result in extremely dry summers, ruining crops and wiping out small farms, or overly wet summer monsoons that flood villages and cause loss of life.
In 2012, the monsoon rains arrived late to India, causing enormous concern about the total rainfall the country would receive. After a relatively dry June and August, however, the rains picked up in September and the season produced an average amount of rainfall. The dry early planting season did disrupt the country's agricultural output, however.
