What Is Weather Definition Kids?

Climate Forecasting

Air pressure changes in the area are what control the weather events. The air pressure is caused by the weight of air. Skies are usually clear and blue when air pressure is high.

The high pressure causes air to flow down and fan out when it is close to the ground. When air pressure is low, air flows together and then upward, where it forms clouds. Local or regional weather forecasts are developed by meteorologyologists.

The weather events that are happening over a broad region are taken into account by the best forecasts. Knowing where storms are now can help predict where storms will be tomorrow and the next day. The process of looking over a large area is aided by the network of weather observations.

The unpredictable nature of the atmosphere means that it will be impossible to predict the weather more than two weeks in advance, but new technologies combined with more traditional methods are allowing forecasters to develop better and more complete forecasts. Climate is the average weather pattern over several decades. Different regions have different climates.

Predicting the future of Earth's weather

The degree to which it is hot or cold, wet or dry, calm or storm, clear or cloudy, is called the weather. The troposphere is the lowest layer of the planet's atmosphere and is just below the stratosphere. Climate is the term for the average of atmospheric conditions over a longer period of time.

Studying how the weather works on other planets has helped in understanding how weather works on Earth. Jupiter's Great Red Spot is anti-cyclonic storm that has existed for at least 300 years. The weather is not limited to planets.

A star's corona is being lost to space, creating a very thin atmosphere throughout the Solar System. The solar wind is the movement of mass from the Sun. Predicting future conditions is no longer an all-human endeavor, but rather a model used to determine barometric pressure, current weather conditions, and sky condition.

Statistical Forecasting of Air Temperature

There are transition zones between different air masses. A cold front brings a rapid drop in temperature and a rise in pressure. It is accompanied by snow and storms in the winter.

It is followed by clearing skies. The warm air mass tends to get ahead of the cold air mass. An anticyclone is a different type of storm.

The winds of anticyclone travel outward. They spin the Northern Hemisphere and in the Southern Hemisphere. The anticyclones are associated with dry weather.

Wind direction may be associated with temperature changes. Warming winds from the south usually bring rising temperatures, while northerly winds usually bring falling temperatures. The Southern Hemisphere has the opposite.

Under cloudless skies temperatures can vary greatly, while clouds keep temperatures consistent. The significance of atmospheric pressure in weather forecasting is limited. If a correction is made for a normal fall in pressure that occurs during the midday hours, it does matter.
