There are two primary ways. First is Doppler radar, which measures winds moving toward and away from the radar to detect features in a storm that can produce a tornado, and sometimes the signature of the tornado itself. Then, by simply looking at where the storm is going they can warn places in the potential path. However, radar cannot determine if a tornado has actually touched down, and can occasionally miss a tornado.
For this reason there are storm spotters. These are people who report severe weather such as tornadoes to authorities. Through such reports meteorologists (weather scientists) can gain a better idea of the potential threat.
What else can I help you with?
How do metorologists know if a tornado is coming?
Meteorologists can detect the signature of a tornado or the rotation that may lead to one using Doppler Radar, which can measure wind speeds at a distance. They also receive reports from weather spotters who report tornadoes and other severe weather as they occur.
Why is knowledge of weather conditions useful?
If we did not know the weather conditions than we could get into big disasters. For example, if we knew that there might be a thunderstorm coming there way or there was a tornado warning, we would be prepared for what might happen.
When is the next tornado in UK?
It is impossible to know when the "next tornado" or other weather event will be anywhere. Weather forecasts don't work that way.
Why is it important to issue tornado warnings as early as possible?
I used to live in Tornado Alley... a tornado watch means that the weather conditions mean it is very likely that a tornado will form in an area. A tornado warning means a tornado has touched down nearby.
When is the next tornado coming and where?
There is know way of knowing that. The development of an individual tornado might be predicted, at most, a few minutes ahead of time
Why Television is Better than Books?
Because books don't tell you the weather that is coming your way. If you have a tornado watch going on in where you live, how would you know? Would reading a regular paper book tell you a tornado's coming for you?
When is there going to be a tornado in Texas?
Tornadoes cannot be predicted in advance like that. So it is impossible to know that. watch the weather channel for tornado warning (s)
What tools meteorologists use to predict and know when a tornado is coming?
Meteorologists use a variety of tools to predict and detect tornadoes, such as weather radar, satellites, weather balloons, and computer modeling. Doppler radar is especially important as it can detect rotations within storms that may indicate the formation of a tornado. Additionally, meteorologists rely on storm spotters, tornado sirens, and public alerts to provide warnings to the public when a tornado is approaching.
Is tornado coming on Sioux falls on 2011 May 30?
That sort of thing is impossible to know.
How do you know when there will be a tornado?
First you should pay attention to local watches and warnings. A tornado watch means that conditions are favorable for the formation of tornadoes. A tornado warning means that a tornado has been detected or a thunderstorm may soon produce one.Conditions to watch for in a potentially tornado storm.Rotation in the clouds, especially with a lowering of the cloud base means that a tornado may soon form. If you see a rotating, elongate or cone-shaped cloud head for cover immediately as it can rapidly develop into a tornado. If this cloud reaches ground level or produces a swirl of dust or debris it means a tornado is one the ground.
How do you know if it is dark that a tornado is coming?
look at the news or check out the NWS website to see if there are any tornado watches or warnings. or if the alarms are going off and you are hiding and the rain stopes really quick that means its right there happen to me 3 times
What does the National Weather Service say about a tornado before it happens?
I'm not exactly too sure what they would say but if you turned on your TV at the time I'm sure they would say something like this: "A tornado has been spotted in Oklahoma. Take shelter immediately." They would definitely warn of the on-coming storm. Even the NWS doesn't know there IS going to be a tornado until it has formed. Whenever weather conditions that may produce tornadoes exist, they issue a "Tornado Watch" for the area. They monitor their equipment (especially the dopler radar) to determine where one MAY be forming and which direction it will travel if it forms. Once a funnel cloud has formed, they issue a "Tornado Warning" and predict it's path.
