Answer 1

1. Most tornadoes form from thunderstorms. You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada. When these two air masses meet, they create instability in the atmosphere. A change in wind direction and an increase in wind speed with increasing height creates an invisible, horizontal spinning effect in the lower atmosphere. Rising air within the updraft tilts the rotating air from horizontal to vertical. An area of rotation, 2-6 miles wide, now extends through much of the storm. Most strong and violent tornadoes form within this area of strong rotation. It is not fully understood about how exactly tornadoes form, grow and die. Tornado researchers are still trying to solve the tornado puzzle, but for every piece that seems to fit they often uncover new pieces that need to be studied.

2, costs and losses to agricultural livestock producers, loss from timber production, urban/residential/commercial impacts, health (injuries) and also;

general economic effects - revenue loss from lost production in business and industry - negative impact of economic multipliers

hope this helps

Answer 2

Tornadoes are not the direct product of air masses meeting. They can form without Gulf or Canadian inflow, else they would have to have gigantic parent storms. Instead, they are the result of a mesocyclone formed when wind shear causes rotation in the central updraft of a storm. This mesocyclone can lower to the ground, usually through a wall cloud, and become a funnel cloud, then a tornado. As the storm intensifies, so to does the tornado, having more shear produced by the thunderstorm. Eventually, when the storm weakens, a tornado will rope out and die. Also, a tornado can simply lift off from the ground without significant weakening on the part of the supercell. Storms that have a history of producing tornadoes will often produce more tornadoes.

The impacts are mostly local, but can be devastating. When the F5 Moore destroyed a section of Oklahoma City, it took a long time for the people involved to recover. Damages were around 1 billion from that single tornado. Despite the localization of the impact, it can be, and often is, devastating, like a small atomic bomb. Greensburg, and more recently Parkersburg, had enormous sections completely wiped off the map, and it will likely still take Greensburg months, and Parkersburg years, to fully recover. Usually environmental impacts are minimal.

Answer 3

Tornados form horizontally in between two opposite direction air currents that shear accross each other in the atmosphere, then dip down to the earth.

The grow quickly, then start to weaken. When in vertical position, surrounding windspeeds can be absorbed by the tornado, adding size.

They die by constantly weakening, and by objects stronger than the winds of the funnel getting in their path, which breaks up some portions of the winds and dissipates the tornado. When you seem to see a tornado stop, it is because the horizontal windshearing going on in the atmosphere has dissipated or moved away. The horizontal circulating continues even when the funnel of the tornado is vertical and touching the ground.

Socially; absolute panic fears of those stuck in the tornado's path, aftermaths inspires others to become compassionate, some in the communities and circles of friends drift apart, others come together for awhile,and so on.

Economically; devastation all around!! Devastation for years!! The responders, etc; need money to exist and operate, The homeowners lose their property buildings, structures, and vehicles, plus most of their worldly possessions, have to burden others for living expenses, businesses lose their inventories and customers locally, and before anyone can recover, they have to rebuild and resupply their lives and families, pets, etc!! Financial recovery never really fully happens. Communities and Residents quickly rebuild their buildings without improving the structural safety of the buildings, ripe for another disaster.

Environmentally, lots of toxins, like home cleansers, automotive supplies, public fed gaslines break and get into the soils, waters, and atmospheres. Not a pleasant nateural environment for months and years.

But not that there is anything wrong with slapping up some shacks to replace decent buildings!!
