How would you define weather?

I don't think so. Your teacher doesn't give a darn what an anonymous tutor online thinks. Your teacher wants to know what each of her/his student thinks.

Weather can be defined as the state of the atmosphere at a particular place and time. It includes various elements such as temperature, humidity, precipitation, cloud cover, wind speed and direction, and atmospheric pressure. To get a comprehensive understanding of weather, you can gather information from meteorological observations and measurements. This may involve using tools such as thermometers, barometers, hygrometers, weather balloons, satellites, and weather radar. Additionally, accessing weather data from trusted sources like the National Weather Service, weather websites, or mobile applications can also provide real-time or forecasted weather conditions.

Thank you Ms.Sue but that is not really what I'm looking for. I'm looking for how would YOU define weather.
