Weather Flashcards
Barometer
barometer
How does a weather man know when it’s going to rain? He measures the air pressure using a barometer. When the barometer shows low air pressure, the weather man knows that bad weather is on its way.
Barometer pressure
The atmosphere is made up of layers of gases. These layers of gases push down on Earth. This push is called barometric pressure
Cirrus cloud
The atmosphere is made up of layers of gases. These layers of gases push down on Earth. This push is called barometric pressure
Climate
Climate is the average weather for long periods of time and in a specific region. The climate in a tropical rainforest is hot throughout the year. The climate in the taiga is bitterly cold during winters and cool during summers.
Could
Where does rain come from? Clouds are formed by tiny drops of water in air. When these drops get bigger and heavier, they fall to Earth. That’s where rain comes from.
Drought
drought
Droughts are prolonged periods of little or no rain. Lack of rain can affect us in many ways.
Dew point
Sometimes you can see tiny dew drops on blades of grass and leaves. How is dew formed? When air is warm it can hold more water vapor. At night air cools down. When the temperature drops below a certain point some vapor changes to water. We see this water as dew. The temperature at which dew is formed is called the dew point.
Cumulonimbus cloud
Sometimes cumulus clouds move upward with rising air. As they rise, they become dark and big. They are now called cumulonimbus clouds. They are also called thunderclouds. These clouds can cause sudden and heavy rains.
Cumulus cloud
Cumulus clouds are white and puffy. They are made up of water droplets. They look like balls of cotton wool in the sky. Cumulus clouds are flat at the bottom and rounded at the top. These clouds can grow upward and develop into thunderstorm clouds.
Forecast
How does your teacher pick the best day for a field trip? She listens to the weather forecast. A forecast tells you what kind of weather you will have. Forecasts are made by studying things like temperature and wind direction
Front funnel cloud
Thunderstorms can make a funnel-shaped column of clouds. This column stretches down from the sky but does not reach the ground. When funnel clouds touch the ground, they are called tornadoes.
Hail
Sometimes, water droplets in clouds freeze. The frozen drops move up into the cloud, carried by strong winds. More ice begins to form on them. When they become too heavy, they fall as hail. Some hailstones can be as large as baseballs.
Humidity
On a rainy day, wet clothes take longer to dry. Why does this happen? This is because air has a lot of water vapor in it. It cannot take water from the clothes as easily as on a sunny day. The amount of water vapor in the air is called humidity.
Hurricanes
Hurricanes are storms that begin over the oceans. They bring heavy rain and strong winds. These winds can have speeds over 100 miles per hour! Hurricanes often destroy houses and pull out trees

Air masses form over large areas that have similar weather. A front is the boundary along which two air masses meet or collide. Different types of fronts bring different characteristic weather conditions. Recording and studying weather patterns makes it possible for meteorologists to forecast the weather.l
