Weather Maps
5th Grade Earth Science
| Question | Answer |
|---|---|
| Define meteorologist. | A scientist who studies weather. |
| What specifically do meteorologists study? | They measure air temperature, humidity, air pressure, wind speed, and precipitation. They track movement of masses of warm and cold air. |
| Define forecasting. | Predicting future weather conditions. |
| Information from what three sources help meteorologists make weather forecasts? | surface measurements, atmospheric measurements, and satellite images. |
| Define weather variable. | Data that meteorologists measure, including temperature, wind speed and direction, air pressure, cloud cover, and precipitation. |
| How are surface-weather maps created? | Weather data collected from stations are sent to weather service computers which create these maps. |
| The shaft on a surface-weather map points in the direction of what? | the wind |
| The number to the left of the shaft on a surface-weather map tells the __________. | temperature |
| The number below the circle and to the left on a surface-weather map denotes the ___ _____. | dew point |
| The three prongs on the shaft (surface-weather map) denotes what? | the wind speed |
| Where is the atmospheric pressure listed on a surface-weather map? | to the right of the staff |
| What does the circle on a surface-weather map represent? | cloud cover |
| What type of symbols are used to represent precipitation on a surface-weather map? | Various dot formations or rays |
| How do you know the difference between the symbols for thunder, a thunderstorm, and a severe thunderstorm? | The ray becomes longer and contains more segments the more severe the storm. |
| What symbols represents rain on a surface-weather map? | Two horizontal dots or four dots in a rhombus formation. |
| What symbols represent snow on a surface-weather map? | Two horizontal asterisks or four asterisks in a rhombus formation. |
| What do the colors black and white represent in the circles seen on a surface-weather map? | white = clear (no/some clouds) black = cloudy (some/many clouds) |
| How are fog and haze represented on a surface-weather map? | Fog is denoted by two horizontal line segments and haze is denoted by a horizontal figure eight. |
| Why are weather balloons released into the atmosphere twice a day? | to measure atmospheric temperature, pressure, and humidity |
| Define radiosondes | An instrument sent into Earth's atmosphere to measure temperature, pressure, and humidity and sends the information to weather stations. |
| Why do meteorologists track a weather balloon's path? | to figure out wind speed and direction |
| What type of information do satellites send to meteorologists? | Track clouds and water vapor, read the temperature of Earth's surface, and identify storm centers. |
| What do meteorologists do with the information sent to them by satellites? | create images of Earth's weather |
| What three forms of information do meteorologists use to create weather maps? | surface measurements, atmospheric measurements, and satellite images. |
| Define weather map. | a way to show weather data as a picture |
| What is shown on a basic weather map? | high and low pressure, temperatures, and places where masses of warm and cold air meet |
| How do meteorologists make weather forecasts? | using a weather map. |
| Define front. | The leading edge of a moving air mass. |
| Where do weather changes happen? | at fronts |
| Define cold front. | The contact zone where a cold air mass overtakes a mass of warm, moist air. |
| What type of front causes a thunderstorm? | a cold front |
| Define warm front. | The contact zone where a warm air mass overtakes a cold air mass. |
| Which type of front causes light rain for a period of time? | a warm front |
| What is the difference between how a cold front and a warm front act? | A cold air mass plows under a warm air mass in a cold front, whereas a warm air mass slides over a cold air mass in a warm front. |
| A blue line with points on a weather map shows what? | The direction in which a cold front is moving. |
| A red line with round bumps on a weather map shows what? | The direction in which a warm front is moving. |
| Define stationary front. | The front formed when a cold front and a warm front come together and stop moving. |
| How is a stationary front depicted on a weather map? | A line with points on one side and bumps on the other. |
| How are high and low pressure areas depicted on a weather map? | H = high-pressure L = low-pressure |
| What is the weather like around a high-pressure center? Why? | The weather is cool and dry because high pressure consists of denser air. |
| What is the weather like around a low-pressure center? Why? | The weather is warm and moist because low pressure is associated with less-dense air. It can also be windy and rainy. |
| When a low-pressure area is near a high-pressure area, air will move from the ____ pressure area to the ___ pressure area. | high; low |
| In what direction does wind blow in the upper atmosphere? | from west to east |
