Weather Flashcards
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.
Barometric 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
You can predict the weather by looking at the clouds in the sky. Some clouds are formed high in the sky and look like feathers. They are called cirrus clouds. Cirrus clouds are white and made up of ice crystals. If you see these clouds in the sky you should expect a change in the weather.
Climate
Climate is a description of the average weather conditions in a region over a long period of time. A desert has hot and dry conditions, while a rainforest is warm and wet.
Cloud
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 dew point
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.
Cumulonimbus 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
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.
Front funnel cloud
You are enjoying a sunny afternoon at the beach. Suddenly, you see thunderclouds forming in the sky. How did this happen? The clouds formed when a mass of cool air runs into a mass of warm air. The area where these air masses meet is called a front. The weather can change very quickly at fronts.
Hail
You are enjoying a sunny afternoon at the beach. Suddenly, you see thunderclouds forming in the sky. How did this happen? The clouds formed when a mass of cool air runs into a mass of warm air. The area where these air masses meet is called a front. The weather can change very quickly at fronts.
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.
Hurricane
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.
Meteorology
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.
Thunder
Sometimes, when it rains, you see big flashes of light in the sky. Lightning superheats the air. Superheating the air causes a loud noise called thunder.
Thunderstorm
Sometimes hot and cold air meet in the atmosphere. The hot air rises above the cold air very quickly. Dark clouds form. Lightning flashes across the skies. These are followed by loud booms of thunder and rain. This is a thunderstorm.
