What is a tornado? A tornado is a mobile, destructive vortex of violently rotating winds having the form of a funnel-shaped cloud and advancing beneath a large storm system. But how do they form.They are usually the extreme result of a supercell thunderstorm. During the storm cold air and warm air combine in a set pattern: the cold air drops as the warm air rises. The warm air eventually twists into a spiral and forms the funnel cloud that we all associate with a tornado
A tornado in Bangladesh was hit by the worst tornado ever. Men, Women, And children walked on the ruins of their city on April 30 1989.The violent tornado carved a path a mile wide and 10 miles long, destroying the towns of Manikganj Sadar and Saturia. An estimated 1,300 people were killed and an additional 12,000 injured. All structures in a 2.3-square-mile-wide area were destroyed along a portion of the path of the tornado, which left an estimated 80,000 people homeless
It affect people on survival and recovery because people without home are homeless and people are injured with no doctor to help nearby
Facts about tornadoes
Most tornadoes travel a few miles before exhausting themselves.
A tornado that occurs over water is often called a waterspout. Weather radars are used to detect tornadoes and give advanced warning.
In the southern hemisphere tornadoes usually rotate in a clockwise direction.
Most tornadoes have wind speeds less than 100 miles per hour (161 kilometers per hour)
What is a Hailstorm? A hailstorm is a storm of heavily hail falling from the sky. Hail forms. when thunderstorm updrafts are strong enough to carry water droplets well above the freezing level
when Doppler radar detected Half Dollar size hail near Stone Mountain, GA, Buford, GA and Snellville, GA on June 1, 2016. This hail storm was traveling SSE at 18 mph and the entire storm produced hail for roughly 2 hour(s). Radar reported a max hail size of 2″ and an average hail size of 1.27″. We estimate that 45,743 buildings were in the affected area and the probability of hail DHI detected was significant.Based on this information, you can expect potential damage to fruit, crops and vegetation, but not much else (Impact Rating 1).thunderstorm updrafts are strong enough . For example In Hail Strike To carry water droplets well above the freezing level. This freezing process forms a hail
. It affects on people's survival because if you are outside and Hail storm begins you will get scratched the only way to avoid it is to stay inside until it's gone.

What are Wildfires? Wildfires are fires that go out of control on Hills,Plantations,And even Forest fires. Sometimes it can be caused by the heating of the sun or lightning strike. Sometimes HUMANS are the ones that cause Fires like cigars,Arson, Campfires.
n Mother Nature Network it says in 1871, during the week of Oct. 8-14, it must have seemed like the whole world was ablaze for residents of the Upper Midwest. Four of the worst fires in U.S. history all broke out in the same week across the region. The Great Chicago Fire, which destroyed about a third of the city's valuation at the time and left more than 100,000 residents homeless, stole the headlines.
But at the same time, three other fires also scorched the region. Blazes leveled the Michigan cities of Holland and Manistee in what has been referred to as the Great Michigan Fire, while across the state another fire destroyed the city of Port Huron. The worst fire of them all, however, might have been the Great Peshtigo Fire, a firestorm that ravaged the Wisconsin countryside, leaving more than 1,500 dead — the most fatalities by fire in U.S. history.
That all of these devastating fires happened at the same time, over such wide distances, has persuaded many researchers that it was no coincidence. In fact, some have even suggested that the fires were caused by a shower of meteorites, fragments from the impact of Comet Biela. Others believe that high winds moving through the region offer a more sensible explanation for the unusual confluence of events.
It affects people on survival,Preparedness, Survival, And recovery because for preparedness you will not know when it's coming so be ready for any moment. It also affects people on survival because a lot of people lose their home and are always homeless so we need to donate to them. It also affects people on recovery because if people get burned or hurt they will need to go to a doctor or get supplies.
Facts on wildfires by do something
- A wildfire (AKA forest or peat fire) is an uncontrolled fire. Wildfires often occur in (duh) wild, unpopulated areas, but they can occur anywhere and harm homes, agriculture, humans, and animals in their path.
- Firefighters also refer to these disasters as surface fires, dependent crown fires, spot fires, and ground fires. Want to make local firefighters happy -- and even better at their jobs? Bake cookies to say thanks! Sign up for Fight Fire With Cookies.
- 90% of all wildfires are started by humans.
- “Crown fires” are spread by wind moving quickly across the tops of trees. “Running crown fires” are even more dangerous because they burn extremely hot, travel rapidly, and can change direction quickly.
- One of the largest fires in recent history was in 1825 when a fire tore through Maine and New Brunswick, Canada, burning 3 million acres of forest.
- Weather conditions can directly contribute to the occurrence of wildfires through lightning strikes or indirectly by an extended dry spell or drought.
- Wildfires can be caused by an accumulation of dead matter (leaves, twigs, and trees) that can create enough heat in some instances to spontaneously combust and ignite the surrounding area.
- Lightning strikes the earth over 100,000 times a day. 10 to 20% of these lightning strikes can cause fire.
- Manmade combustions from arson, human carelessness, or lack of fire safety cause wildfire disasters every year.
- An average of 1.2 million acres of US woodland burn every year.
- A large wildfire — or conflagration — is capable of modifying the local weather conditions (AKA producing its own weather).
