Forecasting Weather Flashcards
A person who makes predictions based on data on atmospheric conditions is
Meteorologist
How far ahead does the weather forecasts predict the weather
3 to 5 days before
Measures wind direction
Windsock
Carries electronic equipment that measures weather conditions above Earth’s surface
Weather balloon
Measures air pressure
Barometer
Measure air temperature
Thermometer
Measures windspeed
Anemometer
Weather balloons carry equipment that measures what three things
Temperature,air pressure,relative humidity
How do weather balloon send measurements to weather stations on the ground
Meteorologists track them
The liquid in a thermometer moves up the glass tube when the air temperature
Increases
In what two ways can a hurricane cause a great deal of damage
Strong winds can knock things down
and storm surges can flood places
Which is not a safety measure during a thunderstorm A tree B stay low to the ground C stay away from water D listen to the radio
Stand near a tree
What does a tornado warning mean
That a tornado has been spotted
What is the most important safety measure during a hurricane
Do not go outside
How does a barometer work
Glass tube put in Mercury
Mercury rises as air pressure increases
The technology that shows the form, amount, and location of precipitation is called
Radar
What is a special type of radar meteorologists use to predict when a tornado might touch down
Doppler radar
As they orbit Earth, what provides images of weather systems that we see on television weather reports
Weather satellites
Where does the National Weather Service get its information for it’s weather maps
From 1000 weather stations
A representation of a weather station on a map is called a
Station model
The lines on a weather map that connect points of equal air pressure are
Isobars
What does an isobar that is a closed circle represent
Areas of high or low pressure
What instrument measures air pressure
A barometer
How does radar help meteorologists forecast the weather
It tells the location, movement, and amount of precipitation
What does a station model represent
A weather station
Why would a meteorologist compare a new weather map with one that is 24 h old
To see if the weather changed
How might several station models from different regions plotted on a map help a meteorologist
It could tell where weather was coming from
