So, you know how sometimes the air around you moves and you feel a breeze? Well, when the air is moving from the east direction, we call it an east wind.
Now, there's a really cool thing called wind patterns, which means the air moves in certain directions based on different factors like temperature and pressure. Sometimes, the air around the earth moves from the east to the west, and that's called an easterly wind.
Now, why is this important? Well, winds can affect our weather and climate. For example, an east wind can bring cool and dry air to certain areas, while in other areas it can bring warm and humid air. So, it's really helpful for people to know which direction the wind is coming from so we can plan our days accordingly.
Overall, east wind just means that the air is moving from the east direction, and it can affect our weather and climate in different ways.
