How survive if there is a tornado

ok..the tornado is a column of air so we need have more care if there is a tornado...some suggestions that you can take into account are:
1. If no basement, go to an interior hallway or small room without windows, such as a bathroom or a closet.
2. Stay away from windows.
3. Get under a strong piece of furniture, such as a workbench, heavy table or desk and hold it.
4. Use arms to protect head and neck.
5. Avoid places with large roofs, such as auditoriums, large halls or shopping malls.
6. Help injured or trapped persons.
7. Turn the radio or television to hear the latest emergency information.

TORNADO

Is a violent, dangerous, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many sizes but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust.



At first, the funnel of the tornado is a funnel cloud, only consists of water droplets on condensation, which rise in the base of the cloud and mother down to the surface. After touching the ground, the vortex scouring powder and abundant hopes that because the air flow upward through the funnel go up and will ensure a curtain of dirt. As the tornado, and because of the friction between air molecules and dust in the walls that form the eye of the tornado usually occurs shock, leading to the appearance of cracks, lightning and lightning.



Finally, with all the debris carried along the funnel, the vortex of the tornado could not keep pace and are lagging behind, separating from the point where it joins with the mother cloud (sometimes drops slightly is wound around the cone) until breakage occurs, when the sleeve and is integrated into the cumulonimbus, the tornado disappeared. Also, the rupture of the funnel can also result from the inability to follow the tornado engulfing air due to the massive presence of the debris bears, but this does not change its dramatic denouement.

HOW SURVIVE IN A TROPICAL CYCLONE

Tropical cyclones out at sea cause large waves, heavy rain, and high winds, disrupting international shipping and, at times, causing shipwrecks. Tropical cyclones stir up water, leaving a cool wake behind them, which causes the region to be less favourable for subsequent tropical cyclones. On land, strong winds can damage or destroy vehicles, buildings, bridges, and other outside objects, turning loose debris into deadly flying projectiles. The storm surge, or the increase in sea level due to the cyclone, is typically the worst effect from landfalling tropical cyclones, historically resulting in 90% of tropical cyclone deaths. The broad rotation of a landfalling tropical cyclone, and vertical wind shear at its periphery, spawns tornadoes. Tornadoes can also be spawned as a result of eyewall mesovortices, which persist until landfall.


Over the past two centuries, tropical cyclones have been responsible for the deaths of about 1.9 million people worldwide. Large areas of standing water caused by flooding lead to infection, as well as contributing to mosquito-borne illnesses. Crowded evacuees in shelters increase the risk of disease propagation. Tropical cyclones significantly interrupt infrastructure, leading to power outages, bridge destruction, and the hampering of reconstruction efforts.

Although cyclones take an enormous toll in lives and personal property, they may be important factors in the precipitation regimes of places they impact, as they may bring much-needed precipitation to otherwise dry regions. Tropical cyclones also help maintain the global heat balance by moving warm, moist tropical air to the middle latitudes and polar regions. The storm surge and winds of hurricanes may be destructive to human-made structures, but they also stir up the waters of coastal estuaries, which are typically important fish breeding locales. Tropical cyclone destruction spurs redevelopment, greatly increasing local property values.



if there is a hurricane you should:
carry a portable radio for information.
carry a cell phone to call if you need help
always look for a high place
lamps do not turn or do not use batteries
if the hurricane is near your house does not leave
Stay away from doors and windows
unplug all electrical appliances

TROPICAL CYCLONE

A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones feed on heat released when moist air rises, resulting in condensation of water vapor contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as northeasters, European windstorms, and polar lows, leading to their classification as "warm core" storm systems. Tropical cyclones originate in the doldrums near the equator, about 10° away from it.

Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active whilst November is the only month with all the tropical cyclone basins active.

The formation of tropical cyclones is the topic of extensive ongoing research and is still not fully understood. While six factors appear to be generally necessary, tropical cyclones may occasionally form without meeting all of the following conditions. In most situations, water temperatures of at least 26.5 °C (79.7 °F) are needed down to a depth of at least 50 m (160 ft);waters of this temperature cause the overlying atmosphere to be unstable enough to sustain convection and thunderstorms. Another factor is rapid cooling with height, which allows the release of the heat of condensation that powers a tropical cyclone. High humidity is needed, especially in the lower-to-mid troposphere; when there is a great deal of moisture in the atmosphere, conditions are more favorable for disturbances to develop. Low amounts of wind shear are needed, as high shear is disruptive to the storm's circulation. Tropical cyclones generally need to form more than 555 km (345 mi) or 5 degrees of latitude away from the equator, allowing the Coriolis effect to deflect winds blowing towards the low pressure center and creating a circulation.Lastly, a formative tropical cyclone needs a pre-existing system of disturbed weather, although without a circulation no cyclonic development will take place.

Nuclear weapon. Can you survive..?

Every living being within three hundred meters from the zero point, will evaporate instantly, because for the first thousandth of a second spontaneous fusion of uranium will cause the air around him reach a hundred thousand degrees Celsius. If we are lucky and we find ourselves at a distance of one kilometer or more from the center of the explosion, we have more chance of survival. At the time that you look a light, you have a second to react. If you can, take advantage of coverage that you have a step or less of you.
In any case, thrown on the floor in fetal position, covering your chest with arms crossed and bowed his head, leaving the lower surface of exposed skin as possible. That protects from heat radiation, the most immediate effect of a nuclear attack, which consists of a bunch of photons. Keep the fetal position for ten seconds, try to expel all the air in your lungs and hold their breath (the air will be very hot, and into our lungs would calcine the alveoli, which would die from asphyxiation).
After those ten seconds, arise quickly and seek a hard cover as the temperature increased a lot, the air is prolonged, and trigger the explosion itself (the blast). This wave drag everything caught in its path with great force, and seeking either choose your coverage, and sure that no glass can explode near you (all glass). Tapao good ears, because all this pile of rubble will miss you over at match three.

When the shock wave has passed, turn to hold your breath, because the atmospheric pressure is practically zero (to dilate the air gap is created). Now comes the second part of the shock wave: all the air has moved, has left a vacuum, and cooled again to the environment, will be re-filled. This is, after the explosion, an implosion coming. Another blast as powerful as the first is to come, but this time from the other side.

If you've come this far, congratulations. The hard part is done.

Now get away of point zero. Uranium that has evaporated in the nuclear fusion in microscopic particles will fall on your town a few minutes. For now, our only enemy is the alpha, but this will be on the ground, so wearing a good shoe and trying not to raise dust to walk, avoids it. In any case, it is always a good idea to take a bath as soon as possible, using citric acid or iodine. This will increase our chances of surviving the beta and gamma radiation.

Then go to police stations, barracks, fire stations, and anything capable of hosting weapons. Then seek to forget the food meat and fruit, are likely to be contaminated. Eat only canned, and salt. The salt will retain water, which will create an extra protection against radiation. The higher our body mass, can absorb more radiation.

Our next goal is to make a water supply. With our weapons and supplies, available time and resources to ensure a site that can draw water

NUCLEAR WEAPON

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive. Even small nuclear devices can devastate a city. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major aspect of international policy since their debut.

In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of World War II. The first nuclear weapon was detonated by United States, in 1945, August 6th in Hiroshima, and the second nuclear weapon was detonated by "Fat man", the American army, in 1945, August 9th in Nagasaki.

some consequences are:
The explosion of the atomic bomb raised the temperature thousands of degrees to melt almost all materials, including clay. The hurricane created by this energy release that evolved in two waves with opposite direction reached 1,500 miles per hour speed.

Thousands of people died on the spot, many volatilized, others burned, and some thrown several kilometers away from its point of origin for the storm unleashed

The sun of death ", the Japanese name given to the effects of radioactive gamma rays, alpha and delta, an imprint of pain caused hundreds of casualties in the bombing. Up to twenty years after the explosion of the survivors died as a result of these things.

Major injuries, according to the radiation dose absorbed due to blood disorder, plastic anemia from leukemia, damage to the epithelial in the skin and mucous membranes, especially in the respiratory and gastrointestinal, with onset of vomiting , nausea and bleeding, skin lesions of the type of acute necrosis and coexist with those of the burns from the blast and heat injuries in the gonadal epithelium, because of further fetal malformations.
