5 Weather Facts for Kids

5 Weather Facts for Kids

Back to school and back to learning! Let’s start the school year off right with some fun weather facts to impress your friend and family. Here are 5 neat weather facts below:

1. Wind comes from changes in pressure



Check out your bike tire! If the pressure inside your tire is higher than the outside air, this may cause your bike tire to pop – you’ll hear a whooshing sound of air. Just like the wind coming out of your tire, changes in atmospheric pressure create wind that we feel but on a much larger scale.


2. Cirrus clouds are made of ice crystals



Cirrus clouds form so high in the sky that only ice crystals can form up there. They form above 20,000 feet (or 6,000 meters) where the atmospheric temperature is well below freezing (-20 to -30 C or -4 to -22 F). These thin and wispy ice clouds form in fair weather conditions and get their beautiful shapes from the strong winds at that altitude blowing them around.


3. Temperature in the sun vs. the shade



Meteorologists define the outdoor ambient temperature as the temperature in the shade. However, most of us don’t sit in the shade the entire time we’re outside, so it can often feel warmer outside that what the temperature sensor is measuring. This is due to the effect of solar radiation on our skin. The temperature in the sun can feel 10 to 15 degrees F warmer than in the shade!


4. Determine freezing rain vs. sleet by the way it hits the ground



Sleet is rain that falls through a frozen layer in the air and turns to ice pellets before reaching the ground. When it hits the ground, it will bounce and not stick to surfaces on the ground.

Freezing rain, on the other hand, is rain that never falls through below-freezing temperatures, but if the ground is below freezing, then the rain freezes when it hits the ground and other surfaces. This creates a dangerous coating of ice on roads and sidewalks.


5. Hail develops during thunderstorms



Some people mistake hail for wintry precipitation like sleet, freezing rain, or even snow. However, hail is in a precipitation category all its own because it only can develop in strong updrafts during thunderstorm development.

As a raindrop falls through a thunderstorm cloud, it can be pushed back up by strong updrafts that strengthen the thunderstorm. This can force the raindrop to the highest levels of the cloud which are so cold the temperatures are below freezing. This will freeze the raindrop and it will become heavy and fall down through the large thunderstorm cloud again until possibly another updraft pushes it back up to the top of the cloud where it can create another frozen layer and grow larger in size.

This cycle continues until the hailstone is larger and heavier than the strength of the updrafts in the thunderstorm cloud. Hail the size of a quarter (1 inch in diameter) or larger is considered severe by the National Weather Service. Rare hailstorms have created large hailstones grapefruit size (4 ½ inches in diameter) and larger which can be very dangerous and even deadly
