Human history is scarred with catastrophic disasters and calamities caused by violent storms or cyclones due to which countless lives have been lost not to speak of other forms of damages. Natural debacles and devastations will continue to occur in the foreseeable future and even the most groundbreaking strides in science & technology will not be able to prevent them from taking place. However, early or advance warning mechanisms have now it made it possible to alert people living in the hinterlands highly prone to storms, cyclones, typhoons, and hurricanes.
Early warning systems now play a crucial role in saving human lives as well as preventing unwarranted loss of livestock, crops, and other economic goods. Following are some of the advance warning systems or mechanisms that are used extensively for sending out warning or alarm signals days before a storm turns destructive.
- RS and GIS
Geographical information systems and remote sensing technologies are now widely harnessed for analyzing weather patterns in zones that are highly susceptible to storms, typhoons, cyclones, and tsunamis.
- Technological Forecasting/Predicting Models
Meteorologists and climatologists in several countries around the world take advantage of meteorological forecasts for making predictions about natural calamities months ahead. These professionals carefully study data relating to rainfall trends and patterns, short-run as well as long-term climatic variations, and other parameters for announcing forecasts having low error margins.
- GSM/CDMA Technology
Mobile as well as broadband networks now make it possible to transmit text messages in bulk to a large number of registered subscribers alerting them about an impending catastrophe.
- Satellite Communication Technology
Advancements made in satellite communication technology have narrowed the time lag or gap between collecting information and sending out warning signals.
- Crowdsourcing via ICT
With more and more people subscribing to Internet connectivity and using smartphones, crowdsourcing approach is immensely helping mapping specialists and humanitarian workers to preparatory measures more effectively.
