  • The Cyclonic Storm BUREVI claimed 9 lives & 200 livestock in Tamil Nadu.
  • The VSCS “GATI” made landfall over Somalia coast.
  • All these weather systems and their remnants and other low-pressure systems caused above normal rainfall over central and peninsular India.
  • The tracks of these cyclones formed during the year are shown in figure 3 (a) and3(b).
High Impact Weather Events

The country also experienced other high impact weather events like, extremely heavy rainfall, floods, landslide, thunderstorm, lightning, cold waves, etc.

Swasth Vayu Non-invasive Ventilator

CSIR-NAL scientists along with medical professionals from CSIR-IGIB came forward to address the shortages of ventilators in the beginning of the Covid-19 pandemic and indigenously designed and developed the non-invasivebilevel positive airway pressureventilator –SwasthVayu, with additional features to treat Covid-19 patients and make the country self-reliant.

SwasthVayu developed by CSIR-NAL is a microcontroller based precise closed-loop adaptive control system with a built-in biocompatible “3D printed manifold and coupler” with HEPA filter (Highly Efficient Particulate Air Filter). These unique features help to alleviate the fear of the virus spread.

Ammoniacal nitrogen in river Yamuna

  • The Central Pollution Control Board (CPCB) convened a meeting on January 04, with the officials of Delhi Pollution Control Committee(DPCC), Haryana State Pollution Control Board (HSPCB), Delhi Jal Board (DJB), Irrigation & Water Resources Department, Haryana and Irrigation and Flood Control Department, Delhi, to discuss the recurring issue of increase in Ammonical Nitrogen in River Yamuna and short and long term remedial actions required. 
  • A study group comprising Delhi Jal Board (DJB), Haryana State Pollution Control Board, Delhi Pollution Control Committee, Irrigation and Water Resources Department, Haryana, Irrigation and Flood Control Department, Delhi has been constituted.
  • The group will reviewuniform monitoring protocol and requirement of strengthening monitoring mechanism, analyse past data and carry out field survey to identify critical hotspots as well as period of high anomia levels.
  • It has also been asked to suggest short and long term measures for sustained solutions, and submit its report within a month. 

Blue Economy is going to be an important source of Aatamnirbhar Bharat: PM
