Weather is what happens in the sky. Weather includes wind, lightning, storms, hurricanes, tornados, rain, hail, snow, and lots more. Energy from the sun affects the weather. Climate tells us what kinds of weather usually happen in an area at different times of the year. Changes in weather can affect our mood. We wear different clothes and do different things in different weather conditions. We choose different foods in different seasons, like ice cream in the summer, or hot chocolate in the winter.
Weather stations around the world measure different parts of weather. Ways to measure weather are wind speed, wind direction, temperature, barometric pressure, and humidity. People try to use these measurements to figure out what the weather will be in the future. These people are called meteorologists. They use computers to build large mathematical models to follow weather trends.
Bad weather can hurt people and their property. It can also just be a bother. Some examples of bad weather are:
Causes of weather [change]
Weather happens because different parts of the Earth get different amounts of heat from the Sun. The equator gets the most heat because the Sun shines straight down on it, while the poles get the least heat because the Sun shines on it from a low angle. Warmer air is lighter than cooler air and goes higher in the air. Water can come with the air and when it cools, the water can go from a gas to a liquid through condensation. Then the water can fall from the sky as rain or snow. After the air goes into the air, it gets colder and goes back towards the ground. Because the air lost its water before, it is dry when it comes back to the ground. As the Earth turns, air moves. This is called wind. The ways that the air moves is one example of the Coriolis effect
