KEY POINTS

·        There are different factors at play in Kerala and Uttarakhand. There have been two rain-bearing ‘low pressure systems’ that are active in the Arabian Sea as well as the Bay of Bengal since the past week.

·        Western disturbances, which are periodic influxes of moisture-laden clouds from the Mediterranean, and common during winter, are what caused the rain in northern India.

·        The Bay of Bengal is still warm and strong winds from there are reaching as far as Uttarakhand and will contribute to rainfall in several parts of north-eastern India.

·        Overall elevated temperatures are also contributing to warmer waters in the Arctic Ocean and drawing colder air from the poles with greater intensity.

·        This added to the increased moisture, thereby seeding more intense western disturbance activity over north India.

·        . The monsoon cycle is prone to large variations, and every year regional factors get accentuated  it’s hard to predict which in advance  that then lead to extreme climate events.

·        This year, India was poised to receive below normal rainfall until August when global meteorological factors changed and caused a torrential September that largely repaired the monsoon deficit.

·        Kerala and Uttarakhand have large tracts of hilly terrain that are prone to landslips. But construction has continued unabated even on land unsuited for human habitation.
