What is Cyclone?
Cyclone, atmospheric pressure distribution in which there is a low central pressure relative to the surrounding pressure. The resulting pressure gradient, combined with the Coriolis effect, causes air to circulate about the core of lowest pressure in a counter clockwise direction in the Northern Hemisphere and in a clockwise direction in the Southern Hemisphere. Near the surface of the earth, the frictional drag on the air moving over land or water causes it to spiral gradually inward toward lower pressures. This inward movement of air is compensated for by rising currents near the center, which are cooled by expansion when they reach the lower pressures of higher altitudes. The cooling, in turn, greatly increases the relative humidity of the air, so that "lows" are generally characterized by cloudiness and high humidity; they are thus often referred to simply as storms.
Overcoming the impacts of a Cyclone requires conscientious preparedness and swift response to the situation. With a contingency plan in place, surviving Cyclone could be possible.
Gramalaya imparts education to the communities towards building resilient Capacity, evacuation on requirement, arranging emergency safe shelter, search and rescue operations, providing relief assistance, involving in repair and reconstruction, initiating economic recovery. This education is imparted to the DPMC-Disaster Preparedness and Management Committee, in turn DPMC will involve its peer model education methodology to empower communities ensuring high survival rate during a cyclone.
How to prepare yourself before a cyclone?
- Develop a cyclone preparedness plan sequencing the activities and responsibilities of each participant.
- Develop a warning and evacuation procedure to face the situation.
- Trim trees and branches near your residence.
- Ensure and establish appropriate stockpile.
- Secure roofing.
- The outdoor items such garden furniture and equipments to indoor.
- Fit windows with metal screens or shutters.
- Heavy objects and furniture should be fastened to the wall.
- Largest and heaviest objects should be placed on lower shelves.
- Water heaters and other appliances should be firmly bolted.
- Fill water containers, lock pets, fill fuel in your cars and place under cover.
- Keep ready emergency supplies and equipment.
- Prepare and keep ready an evacuation kit and a first aid.
- Keep listening to your local radio.
- Never ignore warnings.
What to do during a Cyclone to Survive?
- Remain calm and stay inside.
- If the building starts to break, shelter in the strongest part.
- If outdoors, seek solid enclosed shelter but not a tree.
- If driving, stop at a safe place away from trees, electric beam.
- Listen to your portable radio for cyclonic updates.
- Don't use fixed telephone wires.
- Protect yourself with rugs and blankets.
- Never assume the cyclone is over.
- Strong and violent winds resume soon from the opposite direction.
After the Cyclone
- The survivor of a cyclone has to do the following things:
- Do not go outside unless you are advised officially.
- If you have evacuated, do not go home until you are advised.
- Avoid making unnecessary phone calls.
- Do not go sightseeing.
- Check for fires and utilities and shut off if necessary.
- Check your house for serious damage and evacuate if there is a threat of collapse.
- Check for injuries and administer first aid.
- Clear up hazardous material.
- Turn on a transistor for emergency bulletins.
- Do not crowd the disaster site and keep the streets clear for the passage of emergency and rescue vehicles.
- Never ignore the warning signs.
