How do weather forecasters predict the weather?

Meteorologists use maps charts and computers to analyze weather data and to prepare weather forecasts

What can be learned from the information on weather maps?

Standard symbols on weather maps show fronts areas of high and low pressure types of precipitation and temperatures

Describe the types of weather data gathered by satellites.

images temperature humidity solar radiation wind speed and wind direction and images of clouds and storm systems

Isobar

lines joining places on the map that have the same air pressure

Isotherm

lines joining places that have the same temperature

Meteorologist

scientists who study the causes of weather and try to predict it

How has technology helped to improve weather forecasts?

technological improvements in gathering weather data and using computer have improved the accuracy of weather forecasts

What is the butterfly effect?

the atmosphere works in such a way that a small change in the weather today can mean a larger change in the week later

How does the large amount of weather data gathered by various modern technologies affect the accuracy of weather forecasts?

the more data the better the forecast will be because the more information can be taken into account

How are computers used to produce weather forecasts?

they find temperature humidity air pressure wind speed and direction and other factors

List three technologies used to gather weather data.
