What is Atmospheric Weather

Atmospheric Weather, unless otherwise stated,  refers to the state of the Earth's atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most atmospheric weather phenomena occur in the troposphere, just below the stratosphere. The phenomena above the stratosphere, is usually considered to be more relevant to Space Weather.
The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the complete system. Because it is impossible to accurately know the current state of all parts of the atmosphere, without any error, it is currently theoretically impossible to make useful day-to-day predictions about more than two (2) weeks into the future. However, the more the system is understood and the better the methods for measuring the current state of the atmosphere, the greater the potential for improving the forecasts towards the theoretical best predictions.

Atmospheric Weather Internationally

As an agency of the United Nations, the World Meteorological Organization (WMO) provides a framework for international cooperation and coordination on the state and behaviour of the Earth's atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resource
s. Observational data, information and derived products are freely exchanged in real-time or near real-time between WMO centres and national meteorological and hydrological services around the world.

Atmospheric Weather in Australia

Monitoring and making predictions about Atmospheric Weather in Australia is in the domain of the Bureau Of Meteorology (BOM), among other bodies, such as Universities, and commercial companies. The BOM also deals with climate information that is derived from the long term weather observations.

The Citizen Scientist can also help explore aspects of Atmospheric Weather, using tools such as home weather stations. The effect of these observations can  be multiplied by networking the results from those weather stations to supplement the observations made from official observation stations. Two common examples of networking weather station results are the BOM-supported Weather Observations Website (WOW)  and the commercial Weather Underground website, although others exist.
For those interested in meteorology in South Australia, the Australian Meteorological Association provides an interface to the Bureau Of Meteorology, meeting in the BOM premises every two (2) months.
