What are warm and cold air masses?

Air masses are like giant blankets that cover parts of the Earth, warm air masses feel like a cozy hug from a big, fluffy towel, and cold air masses feel like stepping outside on a frosty morning without a jacket.

Imagine you’re sitting by a fire on a chilly day. The heat from the fire warms up the air around it, that's what a warm air mass is! It forms over places that are usually warm, like oceans or deserts. This warm blanket of air can make the weather feel cozy and sunny.

Now picture yourself jumping into a lake on a winter day. The cold water chills you to the bone, that's what a cold air mass feels like! It forms over cold places, like polar regions or snowy mountains. This chilly blanket of air can bring frosty winds and snowflakes.

When these giant blankets move across the Earth, they change the weather, just like when you switch from a fire to ice water!
