what tools are used to predict blizzards?
150562
A technology used to predict blizzards, is the weather satellite. It's mainly used to moniter the weather and climate of the Earth. The satellite has about 85% accuracy. They can see weather patterns and high and low pressure.

Weather radars send out electromagnetic pulses to measure the location and intensity of precipitation - including rain, hail and snow - in real time. Radar works by sending out electromagnetic pulses and measuring how long they take to return from a target, e.g. an aircraft or a ship.

The Extreme alerts from the National Weather Service include warnings for tsunamis, tornadoes, extreme winds, hurricanes and typhoons. The Severe alerts from National Weather Service include warnings for storm surge, flash floods, dust storms, and snow squalls.

The Snow Day Calculator was started as a middle school side project in 2007 to predict the chance of school closings. This was a unique service where users could enter weather information (that they had to look up) and The Snow Day Calculator would output the likelihood of a snow day the next day.

A snow gauge is an instrument used by meteorologists and hydrologists to measure the amount of snow precipitation over a set period of time. Snow stakes and simple rulers can be used to determine the depth of the snowpack, though they will not evaluate either its density or liquid equivalent.

Radar data can be used to determine the structure of storms and to help with predicting severity of storms. Energy is emitted in various frequencies and wavelengths from large wavelength radio waves to shorter wavelength gamma rays. Radars emit microwave energy, a longer wavelength, highlighted in yellow.

The National Weather Service uses a snowboard to measure snowfall. It has a white surface that absorbs very little sunlight and stays close to the ambient air temperature. But they say any 'cold' surface will do.

Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.
