What types of weather needs to occur in order for a tornado to take place?

Tornadoes require severe thunderstorms to form. Such storms usually occur along a boundary between warm, moist air and either cool air, dry air, or a combination of the two.
Tornadoes also require wind shear, which is where wind speed and direction vary with altitude. By a somewhat complicated process this wind shear gives storms the rotation they need to produce tornadoes.
These rotating storms are called supercells.

What has to happen to a funnel cloud to be classified as a tornado?
Either the funnel cloud or the violent, rotating winds associated with it must reach the ground in order to be classified as a tornado.
How is a storm categorized as a tornado?
A tornado is defined as a violently rotating column of air extending from the base of a thunderstorm to the ground. So in order to be categorized as a tornado, a storm must rotate, connect to both the cloud base and the ground, and have ground level winds strong enough to cause damage.
Do tornadoes have to touch the ground?
Yes. In order to be considered a tornado the vortex, though not necessarily the visible funnel, mus touch the ground.
Can winds 80 miles per hour create a tornado?
Strong winds alone cannot create a tornado. Tornadoes need a specific setup of air movement within a thunderstorm in order to develop. That said, one component believed to play a key role in tornado formation is something called a rear-flank downdraft, or RFD. Winds from the RFD can reach or exceed 80 mph. In terms of tornadoes themselves, 80 mph would be near the upper end of the estimated wind range of an EF0 tornado (65-85 mph).
Why must substances be touching in order for conduction occur?
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
How Can you prevent a Tornado Watch?
In order to prevent a tornado watch you would need to be able to control the weather, which is impossible.
What does tornado watch 4 mean?
A tornado watch is issued when general weather conditions in a region are favorable for the formation of tornadoes. Tornado watches are numbered in the order that they are issued. So tornado watch 4 is the 4th tornado watch issued in the country that year.
Does a planet need an atmosphere to have weather?
Yes, a planet needs an atmosphere in order to have weather.
Does it have to be a warm day in order to have a tornado?
Not always. It is difficult but not impossible for tornadoes to form in relatively chilly weather.
Can a tornado form without a thunderstorm?
No, a tornado cannot form without a thunderstorm. A tornado needs the crossing winds of two air masses to provide rotation in order for a tornado to form. Tornadoes do not form from convection thunderstorms, but only from air mass thunderstorms.
What is a sentence with atmosphere e and weather in it?
A meteorologist needs to understand the atmosphere and how it works in order to be able to forecast weather.
What countries do tsunamis occur in?
a tsunami has to occur an a ocean because their needs to be a large body of water in order for it to be a tsunami
Does a tornado have to touch the ground in order to be a tornado?
Yes
Can a beyblade make a weak tornado?
No, a Beyblade toy spinning on a surface cannot create a tornado. Tornadoes are natural weather phenomena formed by rotating air masses in the atmosphere, which are much larger and powerful than anything a Beyblade can produce.
What does a prairie dog survive bad weather?
I am gonna take this as HOW does a prairie dog (PD) survive bad weather.... They live in tunnels. When it rains, the water will get in there, but there tunnels are so extensive that they are able to find dry areas in there. Of course that doesn't mean a tornado can't suck them out or that they are immune to lightning strikes. --- Leahla
What types of warnings can be issued for a tornado?
There are several levels of advisory involving tornadoes, but only two are actual warnings. Here they are in order of increasing severity:Convective outlook mentioning a risk of tornadoes. (can be issued several days in advanceSevere weather outlook mentioning tornadoes. (tornadoes may be possible)Tornado Watch. (Conditions are favorable for the formation of tornadoes)PDS Tornado Watch. (Particularly Dangerous Situation, strong tornadoes are likely)Tornado Warning. (A tornado has been spotted or one may form soon)Tornado Emergency. (A large, strong tornado is threatening a populated area)Note that a PDS tornado watch is a variant of tornado watch, and a tornado emergency is a variant of tornado warning.
What does a tornado needs in order to form?
There a few conditions that tornades need in order to develop. First, they require an sunstable atmosphere that will favor the formation of severe thunderstorms. Next, they need a fairly high relative humidity, which aids in the final stages of tornado formation. Third, there needs to be wind shear. This is what gives thunderstorms the rotation they need to spawn tornadoes. Most tornadoes are associated with some sort of front, but not all.
