    Heat Waves

    News: India faces threat of deadly heat waves, says UN climate report.

    A Heat Wave is a period of abnormally high temperatures, more than the normal maximum temperature that occurs during the summer season in the North-Western parts of India. Heat Waves typically occur between March and June, and in some rare cases even extend till July. The extreme temperatures and resultant atmospheric conditions adversely affect people living in these regions as they cause physiological stress, sometimes resulting in death.

    The Indian Meteorological Department (IMD) has given the following criteria for Heat Waves:

    Heat Wave need not be considered till maximum temperature of a station reaches atleast 40*C for Plains and atleast 30*C for Hilly regions.

    When normal maximum temperature of a station is less than or equal to 40*C Heat Wave Departure from normal is 5*C to 6*C Severe Heat Wave Departure from normal is 7*C or more.

    When normal maximum temperature of a station is more than 40*C Heat Wave Departure from normal is 4*C to 5*C Severe Heat Wave Departure from normal is 6*C or more.

    When actual maximum temperature remains 45*C or more irrespective of normal maximum temperature, heat waves should be declared. Higher daily peak temperatures and longer, more intense heat waves are becomingly increasingly frequent globally due to climate change. India too is feeling the impact of climate change in terms of increased instances of heat waves which are more intense in nature with each passing year, and have a devastating impact on human health thereby increasing the number of heat wave casualties.

    Digi Yatra

    Air passengers can soon use facial recognition technology to enter any airport in the country under the recently unveiled DigiYatra initiative by the Ministry of Civil Aviation.

    The initiative seeks to promote paperless and hassle-free air travel. There would be one-time verification at the departure airport while travelling for the first time using the ID.

    After successful verification, facial recognition biometric would be captured and stored in the DigiYatra ID.

    With this initiative, the civil aviation ministry is looking to make ticket booking, airport entry and boarding pass security check-in digital. The technology will soon be operational at Bengaluru and Hyderabad airports. The Airports Authority of India (AAI) plans to roll out the initiative at Kolkata, Varanasi, Pune and Vijayawada airports by April next year, as per the ministry.

    Key features of the initiative and how it works:

    1. Centralised registration system for passengers and each of them would get a unique ID on booking the tickets

    2. ID can be created by sharing name, e-mail id, mobile number and details of any identity proof, including Aadhaar

    3. The airline would share the passenger data and the ID with the airport from where the passenger would be flying out

    4. Optionally linking of Aadhaar to airlines at the time of booking for faster airport entry and automated check-ins without requiring any paper-based interventions

    5. A biometrics-based digital processing system for passenger entry and related requirements at the airport

    6. Voluntary for passengers on whether to opt for facial recognition biometric for air travel

    7. The DigiYatra platform would be operational by February 2019

    8. Will be available at major airports in the country

    9. Real-time notifications about congestion and delays of flights

    10. Passengers would be notified when their luggage reaches the baggage claim belt
