If there is a 40% chance of rain on Monday, 50% on Tuesday, and 40% on Wednesday then math tells us that there is a 82% chance of rain over those 3 days. Lately I have seen percentages listed for each hour of the day. For example, a 60% chance of rain for 7, 8, 9, 10, and 11 in the morning. Does that mean there is a 99% chance of rain that morning?
satellites
Meteorologists test the air pressure, temperature, humidity and those sorts of things. They also send out people to view the weather, and they make a prediction by using the results. Satellite imagery is also used.
First of all let us define what such a device is. An anemometer is a device that can be used to measure wind speed or air pressure. Such a device would be used by meteorologists, or people who predict weather using scientific methods.
Simple weather measurements can be done using a thermometer (temperature), gauge (rainfall or snow), barometers (atmospheric pressure), humidity (water vapour present in the air), weather-vane (indicating wind) and visual observations (cloud amount).
no Actually yes they are, the US National Weather Service uses them to make extended forecasts out several weeks repeating updating them using the lasted collected data every few minutes.
They show fronts, which are wind gusted air masses that change weather.
Meteorologists predict the weather.
Weather maps show changes in wind directions, cloud and storm formations. Meteorologists can tell when a hurricane is forming or when a rain storm is coming by using this map.
The main advantages are that it provides the same quality of weather reporting that meteorologists use and its 24 hours a day. The service is totally free and does not require wifi to function.
A meteorologist is someone who studies weather and uses information from Doppler radar, weather satellites, computers and other instruments to make weather maps and provide forecasts. A station model indicates weather using a combination of symbols on a map.
yes, to a limited degree. By using tools like Doppler radar meteorologists can predict approximately where and when a tornado is likely to occur. Still, even with a combination of radar and weather spotters we cannot predict the exact path a tornado will take with certainty.

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.

Meteorologists track tornadoes using Doppler radar, which can detect rotation in a storm, and reports from eyewitnesses.
