What is Weather Disturbance?
When you look at the sky, what do you notice about the clouds? Do the clouds cover the Sun? What can be the effect of this condition to the blowing wind?
Weather changes whenever these things in the atmosphere change.
The atmosphere around us behaves in many different ways. It changes when it is hot or cold, and also it changes when it is wet or dry. It behaves differently when it is clear or cloudy, it changes when the sky is calm or stormy.
A snowfall is part of weather as well as thunder and lightning. Sometimes, the atmosphere acts violently and sometimes, it is peaceful and quiet.
Weather is the day-to-day atmospheric conditions, including temperature, rainfall, wind, and moisture at any given place. Weather changes right now, it will change tomorrow, and change in the very near future.
The atmosphere is important because it makes part of what makes Earth livable. Atmosphere can blocks some of the Sun's dangerous or harmful rays or radiation from reaching Earth, such UV rays. It traps the heat and make the Earth into a comfortable temperature. And the oxygen that we use to breathe within our atmosphere is essential for life.
