Strong Tornadoes Heading Toward Dhaka

May 27, 2014
A strong tornado has been approaching the capital of Bangladesh, Dhaka. The 14 million people living in Dhaka are going to have to follow the precautions listed by the Bangladesh Red Crescent Society. This tornado looks like it has the potential to cause major problems for the people of Dhaka.
What is happening?
This tornado doesn’t look like a typical funnel or classic tornado appearance. This storm’s huge funnel is a mile wide and is sometimes unrecognizable as tornado up close. They lack the classic narrow funnel appearance, instead appearing as a boiling wall of fog approaching out of nowhere, which explains their location close to the rain. Usually the rain stops and the tornado makes a rapid appearance, which causes people to observe the storm instead of taking shelter.
What is causing the tornado?
Tornadoes form from the conversion of warm, moist air and cool, dry air, creating an instability in the atmosphere. This then creates a super cell or large thunderstorm. As the speed and direction of wind increases, it creates an invisible spinning effect. As a tornado has now been formed within the storm, it is only a matter of minutes until it will touchdown. It usually happens in areas where winds of all levels can occur. The conditions required to form a tornado include a low level of moisture, a cold front, and an unstable atmosphere when the temperature decreases rapidly with height.
How is it affecting people and the city?
The Enhanced Fujita Scale is one of a few ways that the intensity of the tornado is determined. This scale ranges from EF0- EF5. EF0 causes damage to trees but no damage to substantial structures. EF5 is when the tornado is strong enough to rip buildings from their foundation and can also deform skyscrapers. The Torro Scale is another scale used to determine the intensity of a tornado. T0 is used if the storm is extremely weak and T11 is the most powerful known tornado to ever happen. The tornado can cause contamination of water, which can lead to sickness and disease. Tornadoes also affect the economic situation in the city; the destruction of buildings and workplaces can lead to higher unemployment rates and a lower GDP.
What should I do during the disaster to stay safe?
Before the storm, create a family plan and discuss it. Also, create an emergency kit that includes enough food and water for at least 72 hours and be sure to have first aid supplies, clothes, and toiletries as well. You may also want to have a radio or something to receive updates as the storm progresses.
During the storm, know what to be watching for. Tornadoes usually occur within or very near large thunderstorms so being aware of where the storm lies is a good idea. If you are unaware of what to be looking for in this situation, rotation, a roar
that may sound like a jet, debris whirling near the ground, and darkening skies may indicate the presence of a tornado. Although you may not see any signs there could still be a tornado near, check to be sure by looking at a local radar online or by watching the news. Another way to be aware of a tornado is to listen for watches or warnings when something in the sky doesn't seem right.
When the tornado strikes, shelter is the most important thing to seek when a tornado hits. It is suggested to find a strong structured building. Duck and cover in a room without windows that is not bordering an outside wall. The only thing to do once finding a safe place to stay is wait until you are given a notice that it is okay to come out.
What should I do after the disaster?
Once the storm is over, deal with any injuries first. Depending on the damage, inspect the area. Always be aware and cautious of your surroundings. Wear sturdy boots, long sleeves, and gloves when cleaning up the debris. Continue to listen to the emergency radio or television for more information on the storm.
