“March comes in like a lion and goes out like a lamb.” This saying in English is very clear and easy to understand- the beginning of March, at least here in the Northern Hemisphere, roars in and is usually cold and blustery, and by the end of the month the weather is milder, gentler, and more spring like.
But where does all the wind come from?
A fast explanation:
The air surrounding our planet is all different temperatures. In the spring, some areas warm up faster than others, which creates pockets of warm air and pockets of colder air. The warmer the temperature, the higher the pressure, and the more quickly the air expands and moves. When air of two different temperatures meet, they try to balance each other. As the temperature continues changing, the air moves more or less quickly. Add in another factor- the rotation of the Earth- which means slowly the Earth is moving around the sun in a way that heats the Northern Hemisphere a bit more each day, and voilà! Wind!

- Blustery- windy
- Mild- a pleasant temperature, not too hot not too cold
