HailRed

__** Hail **__ Emil B & Grandin B Red Class Introduction Hail is when water drops are lifted high up into the atmosphere and freezes therefore causing a very dense body falling to the ground. Hail is a major natural disaster in some states and in different parts of the world. Hail can affect peoples lives because of the strength and speed they have. Hail is dangerous and something people or animals should stay away from. If People are stuck outside during a Hailstorm they may be severly hurt before finding shelter.(2)



Dangers Hail can hurt people and damage things like cars, crops, and kill farm animals if they are not protected. Loss of human life is also a risk of hail because they can be from the size of a little nut to the size of a softball coming from the atmosphere. With the speeds they come with they are even more dangerous because the force of the ice can crack a skull open. If hail is occuring in your area you should not be outside but you should be inside your home because it is safer. (2) There are many pictures that show cars that have their wind sheilds shattered by big chunks of hail that has fallen, there are also many pictures that show houses that have broken windows. So when there are hail storms, around, you should stay inside. (7) There is a video that we have that shows a storm coming and making a huge hail storm, in the video it shows this family pool splashing like crazy as big chunks of hail come down. (9) In Bangladesh, a giant storm of "grapefruit sized" hail killed almost a hundred people in 1986. Some of the hail stones weighed more than two pounds.

Conditions of Formation Hail is formed by updrafts and down drafts of warm and cold winds in a thunderstorm. When water droplets catch on to a warm air updraft the droplet can reach up to heights that have temperatures below freezing and therefore they freeze and turn into hail. When they are frozen they are too heavy and then are caught by down drafts and brought to the ground with a very large force. When it hits the ground it can be very dangerous because the force of the hail can kill someone. (4)



Historical Examples (3) 14th April 1999, a major hailstorm strikes Sydney. After hitting densely populated city of Sydney it then moved on to Broken Bay and did most of its damage there at 10 pm at night. It was a disaster because it was at night and it came by surprise to Broken Bay. The storm damaged about $2,200,000,000 dollars worth of property. It was hard for people to get the money to get their property back because the hail had destroyed cars, homes and killed dozens of people. This is the worst recorded hail storm yet. (9) In 1888 a hail storm in India almost wiped out more than 1,600 animals. (9) In 1979 and 1981, there were some accounts that babies had their skulls broken by hail.

Safety **Car:**To be safe from a hail storm when you are in a car you should, stay away from the windows, lie on your stomach with your head facing down, cover children that are younger than you and never look up at the windows because they can shatter into your eyes. (1) **Home or Building:** To be safe in a building you should stay inside and don't go near your basement or windows because they are more likely to be struck by the hail. Take care of your children struck by the hail. Take care of your children and don't run outside.

**Outside:** Don't ever put others in risk of getting hurt. Take care of your pets and livestock when you are outside. Protect your head and neck or find a stable shelter that is not able to be damaged by the hail. (1)
