How do we know what the weather will be like?

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

How do clouds form for kids?

A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!

How can they predict rain?

Meteorologists also use satellites to observe cloud patterns around the world, and radar is used to measure precipitation. All of this data is then plugged into super computers, which use numerical forecast equations to create forecast models of the atmosphere.

What do clouds look like?

Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both. The water and ice scatter all light, making clouds appear white. If the clouds get thick enough or high enough all the light above does not make it through, hence the gray or dark look.

How can you tell the weather with clouds?

If your clouds are low, fluffy, and white like cottonballs in the sky, then the weather is okay. However, keep an eye on these for any vertical growth of the cloud upwards into the sky (turning into anvil shapes). These clouds can unexpectedly change from fair weather indicators into violent thunderstorms.

How are cumulus clouds used to predict the weather?

Cumulus clouds commonly have rounded tops and flat darker bottoms. Those with little vertical development indicate that the weather will be fair. Cumulus clouds can also grow vertically forming cumulonimbus clouds. These clouds indicate heavy rain and severe weather.

How are we able to predict the weather?

Being able to predict the weather by observing cloud formations is a skill that is somewhat lost on us modern humans. Most of us can easily look at a cloud and see the unicorn or ice cream cones, but very few of us can look at clouds and see the approaching cold front. Fortunately, being able to predict the weather is easier than one may think.

Which is the best description of a cloud?

Clouds can easily be broken into four categories. These categories are high clouds, middle clouds, low clouds and clouds with vertical growth. Clouds are also identified by shape. Cumulus refers to a “heap” of clouds. Stratus refers to clouds that are long and streaky.
