From Dog Walking To Weather And Climate

There is much more variation in the path that the dog takes as compared with the man, but they are both headed the same way. Similarly, weather can be highly variable and climate means long term trends.

Hazardous Heat Waves

Heat waves are abnormally hot weather that occurs over a few days to several weeks, and climate change is making them worse. Watch and find out why heat waves are a hazard and what you can do to stay safe when they happen.

How Hail is Made in Storms

How do hailstones form, and why are some much larger than others? Watch to learn how hail can form during a thunderstorm.

Is it Going to Snow?

Why is it so hard to predict when we’ll have a snow day? Find out what factors determine whether precipitation will fall as rain, sleet, or snow!

Making Clouds

Clouds are made of water or ice crystals, but how do they form? Learn more about cloud formation and when it’s likely to happen

Meet a Hurricane

Learn what makes a hurricane a hurricane, as well as how these storms can cause damage from storm surge, heavy rain, and fierce winds.

Meet a Tornado

Learn what makes a tornado a tornado, and how these powerful storms can cause property damage and are a threat to our safety.

No Two Hurricanes Are Alike

When there is a hurricane or tropical storm heading towards the coast, get to know all about it to learn what hazards it could cause.

Satellite Signals from Space: Smart Science for Understanding Weather and Climate

This video explains how COSMIC satellites monitor our atmosphere, collecting data that is used to improve weather forecasts, monitor the upper atmosphere, and understand our climate.

Simulation of Global Weather

Supplemental Teacher video for GLOBE Weather Lesson 15

This video on the Coriolis effect is a supplemental teacher resource for Lesson 15, Part 2 of the GLOBE Weather Curriculum. Using a balloon and a marker, they create a simple model to observe the Coriolis effect.

Supplemental Teacher video for GLOBE Weather Lesson 5

This video on convection is a supplemental teacher resource for Lesson 5 of the GLOBE Weather Curriculum. In this lesson, students watch a demonstration of warming up and cooling down the air inside a Mylar balloon that has been partially deflated.

The Shape of Raindrops

Did you know that raindrops are not shaped like teardrops? They actually look like tiny hamburgers falling through the sky. Watch this video to learn why!

Visualization of Global Temperatures

This animation shows hourly air temperature from January 1 to February 24, 2014.

Weather Balloon Launch Video

In this video from the U.S. National Weather Service, a scientist explains how weather balloons are used to collect data that improves weather predictions.

What Makes a Bomb Cyclone

A bomb cyclone can cause cold and stormy winter weather. Watch this video to discover what makes a bomb cyclone.

What Makes Cities So Hot?

A city can be several degrees warmer than the surrounding area. Learn how this phenomenon, called the urban heat island effect, occurs and find out what can be done to keep cities cool.

What Makes Snowflakes Take Shape?

Do you know that snowflakes are different shapes? Find out why some snowflakes have simple shapes and others are more intricate.

What's the Polar Vortex?

Learn about the polar vortex and the polar jet stream and how we can get particularly chilly winter weather in the mid-latitudes when the air circulating around the North Pole wobbles to the south.

What's With Weather Fronts?

Discover how a weather front can cause clouds and storms with rain or snow.
