CONTEXT:

According to the India Meteorological Department (IMD) data, October 2018, was the driest month for the country since 1976. In fact, the rainfall for the month was even lower than that drought years.

Although, the actual deficit last monsoon was modest — barely 10%. But the post-monsoon rainfall (October to December, 2018) has registered a 44% deficit. This national average deficit conceals shortages in some regions where it is much higher. In Marathwada and Vidarbha, the deficit is 84%, and 88% respectively. This low-rain and no-rain situation is going to aggravate the water crisis in India.

IMD Data: At a Glance

2018 was declared the sixth- warmest year since 1901, when recording started. Pointing towards changing weather and climate parameters, IMD also noted that the last monsoon rainfall was the sixth-lowest since 1901.

From IMD’s analysis, it is clear that India is witnessing consistent warmer seasons and pointed out that 11 out of 15 warmest years were in the last 15 years (2002-2018). The last year was also the consecutive third-warmest year after 2016 and 2017.

The past decade (2001-2010/2009-2018) was also the warmest on record, with anomalies of 0.23°C/0.37°C. The annual mean temperature during 1901-2018 showed an increasing trend of 0.6°C/100 years, with a significant increasing trend in maximum temperature (1.0°C/100 years), and relatively lower increasing trend (0.2°C/100 years) in minimum temperature.

A warming trend is now witnessed in all seasons including the winter (January-February). The country averaged season mean temperatures during all the four seasons, with the winter season (January-February, +0.59°C) being the 5th warmest since 1901 and the pre-monsoon season (March-May, with an anomaly of +0.55°C above average) being the 7th warmest ever since 1901.
