Mains Paper 3: Disaster Management | Disaster & disaster management
From UPSC perspective, the following things are important:
Prelims level: Cyclone Warning Systems of IMD
Mains level: Increasing incidences of tropical cyclones
- A ‘yellow alert’ was issued in the Andaman and Nicobar Islands Saturday as Cyclone Pabuk made its way towards the archipelago.
- The cyclone was originated over the Gulf of Thailand.
- It has moved west-northwestwards with a speed of 10 kmph and lay centred over Thailand and neighbourhood.
Weather Warning Systems
- Colour coded weather warning system is used to alert the public to the predicted severity of weather: cyclones, floods, storms and winds.
- The colour system ranges from green, which is low risk, to red, which is the highest risk of severe conditions.
- Lets overlook these:
- Yellow level weather alerts is to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action.
- It is used for weather conditions that do not pose an immediate threat to the general population, but only to those exposed to risk by nature of their location and/or activity.
- Orange level indicates the weather conditions which have the capacity to impact significantly on people in the affected areas.
- Its issue implies that all recipients in the affected areas should prepare themselves in an appropriate way for the anticipated conditions.
- Red level severe weather warnings should be a comparatively rare event and implies that recipients take action to protect themselves and/or their properties.
- This is usually done by moving their families out of the danger zone temporarily (evacuation), by staying indoors or by other specific actions aimed at mitigating the effects of the weather conditions.
- It is in the case of a red weather alert that we could see serious disruption to public transport, road closures and school closures.
