How would it look outside if a tornado were approaching?
Tornadoes occur during severe thunderstorms are very usually precedes by very heavy rain which, depending on the storm, may or may not stop before the tornado hits. This rain may be accompanied by hail, which can reach very large sizes. Many people have noted green or other unusual colors in the sky before a tornado. While this usually indicates a severe thunderstorm, it does not mean a tornado is coming, nor does its absence mean there won't be one. The tornado itself usually occurs in the rear half of the thunderstorm, if that portion of the storm is rain-free you may note a lowering of the cloud base and rotation in the clouds; this is the wall cloud from which the tornado may form. Near this wall cloud a hole may open up in the clouds, showing the location of the rear-flank downdraft that plays a crucial role in tornado formation.
How big is the biggest F5 tornado?
It is not known for certain, but a likely candidate was the tornado that hit Seneca, Kansas on May 27, 1896. At one point the tornado was 2.2 miles wide. The largest tornado ever recorded was the El Reno, Oklahoma tornado of May 31, 2013, measured at one point to be 2.6 miles wide. This tornado was officially rated EF3 as it was over open country when it reached peak intensity and so caused relatively little damage at that point. Radar analysis, however, suggests that it may have reached EF5 intensity.
Why do tornadoes almost always start in empty fields?
Tornadoes often form in open fields because the flat terrain allows warm air from the ground to rise easily. This rising warm air meets with cool air aloft, creating instability that can trigger the rotation needed for a tornado to form. Additionally, open fields have less friction to disrupt the rapidly rotating winds that fuel tornado development.
What is the weakest tornado ever recorded?
That is difficult to determine. There have been many thousands of F0 and EF0 tornadoes with winds possibly as low as 40 mph. However it is difficult to determine which were the weakest as many took place in open fields and caused no damage and all but perhaps a few never had their winds measured. Even then, it could be debated whether a tornado with winds as low as 40 mph could actually be counted as a tornado as such winds usually cannot cause significant damage.
What was the biggest tornado in the 1970's?
The largest tornado of the 1970's hit Boone and Kenton Counties in Kentucky on April 2, 1977. It was 1.7 miles wide, but because it tore mostly across open countryside it did not do heavy damage and was only rated F1. There were no fatalities. The deadliest tornado of the 1970's was an F4 that struck Mississippi on February 21, 1971, killing 58 also making it the deadliest tornado in Mississippi history. first touched down near the Louisiana border southwest of Cary and tore a damage path 202 miles long (one of the longest ever recorded), dissipating a few miles north of the Tennessee border. The most destructive was an F5 that Struck Lubbock, Texas on May 11, 1970. It caused $250 million in damage, which is equivalent to over $1.4 billion in todays dollars, marking it as the second most destructive tornado of all time. Which tornado was the strongest of this decade could go to any one of the 14 F5 tornadoes that touched down, but one particular candidate of interest was the tornado which struck Xenia, Ohio on April 3, 1974. It was most certainly one of the most intense tornadoes ever recorded.
Why do you need to open windows when there is tornado?
You don't. You should actually keep the windows shut to try to prevent wind from entering your home.
Is it a good decision to open windows in your house if a tornado is approaching?
Do not even think about opening windows and doors if the tornado is very close. Take shelter where ever possible and do so immediately. No house is worth your life.No. If the center of a tornado ever passed over your house, the wind and debris it was carrying would already have broken at least a few windows before any significant pressure difference could cause problems. It's not likely that this difference is even enough to do much to a well-built home anyway, especially when most houses have enough openings and vents as it is.
Is it a good idea to open your windows during a tornado?
No, it is not a good idea to open your windows during a tornado. Doing so could increase the likelihood of debris entering your home and causing damage or injury. It is better to seek shelter in a safe, interior room away from windows.
Is it true that A highway overpass is a good place to hide from a tornado?
Usually - yes. If you're caught out in the open and a tornado is approaching... the safest place to shelter is underneath the overpass - as high up the sloping bank as possible.
When should you open all windows and hatches when you need to refuel your boat?
you should open all windows/hatches after fueling your boat
Do you open windows before a tornado comes?
No. Opening windows will only expose the interior of your house to more damage. If there is a tornado in your area take cover immediately! The idea that opening windows to equalize pressure will save you house is a myth. The pressure difference inside a tornado is not enough to cause significant damage. This has been mathematically proven. Tornadoes produce damage though their powerful winds, and in any tornado strong enough to significantly damage a house, the windows will break anyway.
What program should you use to open videos?
