Humid continental climate is a type of weather that happens in some parts of the world. It’s like the weather that you might have in spring or fall: sometimes it's warm, sometimes it's cool, and sometimes it rains a lot. In the humid continental climate, the temperature can change a lot during the year. When it's summer, it can be really hot and you might want to wear shorts and play outside. But in winter, it can be really cold and you'll need to wear a warm coat and gloves.
Humid continental climate also means that there is a good amount of water in the air. This can cause humidity - when the air feels really sticky or damp - and it can make the weather feel even hotter in the summer and even colder in the winter. All of this can affect the plants and animals that live in the area. For example, animals might hibernate in the winter when it gets too cold, or plants might lose their leaves when it gets too dry.
Overall, humid continental climate is a type of weather that can change a lot during the year, with different temperatures and amounts of water in the air. It affects the world around us and is important to understand when living in or visiting areas that have this type of climate.
