Here's a simple explanation of weather: it's what happens outside. The air, or atmosphere, around us behaves in different ways. It changes when it's hot or cold, and when it's wet or dry. It acts differently when it's calm or stormy, and clear or cloudy. The atmosphere reacts to everything from rain to sunshine.
A snow flurry is weather. Thunder and lightning are weather, too. Sometimes the atmosphere behaves violently, and sometimes it's peaceful and quiet. Either way, it's weather. Meteorologists record the weather every day. The constant recording of weather information helps to determine the climate of an area.
Climate is the average weather in a location over a long period of time. A place that doesn't get much rain over many years would have a dry climate. A place where it stays cold for most of the year would have a cold climate.
Climate is useful for weather forecasting. It also helps determine when the best time would be for farmers to plant their crops. It could even be helpful for you and your family to plan a vacation.
In other words, look out your window any day, any time and you see weather. Look out your window every day for a month or longer, observe the weather each day, and you can determine the climate.
Weather is the day-to-day changes in temperature, air pressure, moisture, wind, cloudiness, rainfall and sunshine. Such changes arise from the movement of air in the Earth's atmosphere and the accompanying transfers of heat and moisture. This heat and moisture transport generates the weather features and systems which we see and experience, including clouds, fronts, depressions and anticyclones.
Weather is what is happening in the atmosphere at any time or short period of time. Weather conditions can change suddenly. Today may be warm and sunny, tomorrow may be cool and cloudy. Weather conditions include clouds, rain, snow, sleet, hail, fog, mist, sunshine, wind, temperature and thunderstorms.Weather is driven by the heat stored in the Earth's atmosphere, which comes from energy from the Sun. When heat is moved around the Earth's surface and in the atmosphere because of differences in temperature between places, this makes winds. Winds form part of larger weather systems, the most powerful of which is the hurricane. Other weather features like the thunderstorm also develop because of the movement of heat in the atmosphere. Some thunderstorms in the United States give birth to tornadoes.
Like energy, water is moved between the Earth and the atmosphere. The Earth's water cycle plays an important role in the development of many weather features like dew, fog, clouds and rain.
Scientists measure the weather so they can forecast it. This involves plotting weather information on special charts. Weather radar and satellites are now also used to help predict the weather.
