Vocabulary Meteorologist- Scientist who study the causes of weather and try to predict it. 2.Isobars- A line on a weather map that joins places that have the same pressure. 1.Isotherms- A line on a weather map that joins places that have the same temperature.

Predicting the Weather pg. 217 Red Sky Many people use creative thought to summarize their own observations of weather.

How Do you Predict the Weather? Pg. 217 The first step in forecasting is to collect data. direct observations, recognizing that cumulonimbus clouds may produce a thunderstorm This can be done either through: through the use of instruments such as a barometer Meteorologists are scientists who study and try to predict the weather. Interpreting Complex Data: Meteorologists use a variety of resources such as: maps, charts, computers, and other technology to analyze weather data and to prepare weather forecasts.

How Do you Predict the Weather? Pg. 217/218 Weather reporters get their information from the National Weather Service, which uses weather balloons, satellites, radar, and surface instruments to gather data. Technology Weather balloons carry instruments into the troposphere and lower stratosphere to measure temperature, air pressure, and humidity. Satellites in the exosphere, the uppermost layer of the atmosphere, collect data on temperature, humidity, solar radiation, and wind speed and direction.

How Do you Predict the Weather? Pg. 217/218 Technology They also include cameras that can make images of clouds, storms, and snow cover. Automated weather stations in 1,700 surface locations gather data on temperature, air pressure, relative humidity, rainfall, and wind speed and direction. Computers help process all of this weather data quickly to help forecasters make predictions. Currently, forecasts are fairly accurate up to five days in the future.

What Can You Learn From Weather Maps? Pg. 219 The National Weather Service maintains weather maps that are snapshots of conditions at a particular time over a large area. Some show curved lines that connect places where certain conditions are the same. Isobars (-bar as in barometer) are lines joining places on the map that have the same air pressure. (These readings may be given in inches of mercury or in millibars.) Isotherms are lines joining places that have the same temperature. They may be labeled in degrees Fahrenheit, degrees Celsius, or both. Standard symbols on weather maps show fronts, areas of high and low pressure, types of precipitation, and temperatures.
