How is damage from tornadoes measured?
Damage from tornadoes is assessed by engineers and meteorologists, who assign wind speed estimates based on the severity of damage and the type and quality of structure impacted. The wind speed estimates are then used to assign a rating, which can range from EF0 at the weakest to EF5 at the strongest.
What tool used to rate tornado strength?
Tornado strength is assessed on the Enhanced Fujita scale. It is not so much a tool as a set of guidelines. Meteorologists and engineers survey the damage done my a tornado, using it to estimate the wind speed at various points along the path. The highest wind speed is used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.
What would you use to measure wind?
An 'anemometer' measures speed of windAn 'anemometer' measures speed of wind
Do tornados' low pressure often makes houses explode?
No. That notion is a myth that has been debunked. Tornadoes destroy houses with wind and debris.
What messures wind speed?
The simplest way to estimate wind speed is from observed phenomena. This is the basis of the Beaufort scale, where zero can be recognized by vertically rising smoke. As this method is only approximate, each value on the scale represents a range of speeds; for example three on the scale represents wind speeds between seven and ten knots. For hundreds of years, the anemometer was the most accurate method of measuring wind speeds close to the ground. The simplest anemometers are based on a rotating vane, but most professional measurements are now made with a heated wire anemometer. The heated wire anemometer consists of a bare metal wire exposed to the wind which is heated by passing electrical current through it, as the wire becomes hotter its resistance increases and by measuring the temperature of the wind, the current flowing into the wire and the wire's resistance (and thus indirectly its temperature) the wind speed can be calculated. Wind speed is important to air navigation. In an aicraft, wind speed relative to the ground can be calculated by using using on-board instruments to measure the wind speed relative to the aircraft, and the plane's speed relative to the ground. Such reports can be used to confirm wind speed forecasts. The development of accurate electronic navigation systems, including inertial navigation and GPS enable this calculation to be done automatically. Modern GPS and inertial systems often include a direct readout of the current wind speed and direction. Wind speed can also be estimated using radar to measure the Doppler shift due to velocity of air. This method is now used very often by meteorologists
Where do meteorologists get there barometric pressure data?
from the barometer it measures wind speed
What technology is used to monitor and predict the weather?
broadcasting meteorologists use what technology ? broadcasting meteorologists use what technology ?
Do you use a hydrometer to measure wind speed?
To measure wind speed you use an anemometer. These are sometimes called wind meters. Meteorologists use anemometers to help predict weather.
Could 10-20mph cause a tornado?
Tornados are not the result of any wind speed. Tornados develope under certain atmospheric conditions which are still not fully understood.
Why do meteorologists use an anemometer?
An anomometeris important because if a metoroligist didn't have anomometers they wouldn't have known how hard the wind is blowing and in what direction. So a anomometer measures the wind speed and what direction it's going in.
What is the function of wind rose?
A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location.
How meteorologists measure changes in weather?
Meteorologists use many different tools for different needs. Most people are familiar with thermometers, barometers, and anemometers for measuring temperature, air pressure, and wind speed, respectively. Meteorologists use other tools. For example, weather balloons are special balloons that have a weather pack on them that measures temperature, air pressure, wind speed, and wind direction in all the layers of the troposphere.

How do a meteorologists determine the difference between a tropical storm and a hurricane?
By measuring the sustained wind speed. If the wind speed of a tropical cyclone is anywhere in the range of 39 to 73 mph then it is a tropical storm. If the wind speed is 74 mph or greater then it is a hurricane.
Who Studies Wind?
Meteorologists study wind.

What are funnel shaped wind storms?
Tornados
