Meteorology is the study of the Atmosphere that focuses on the weather process and forecasting. In simple terms, it is the study of the changes in atmospheric parameters such as temperature, air pressure and wind direction. It can also be defined as the scientific study of the Atmosphere. Meteorology creates weather predictions on a daily bases as well medium and long term.
Meteorology can be divided into a number of different fields. Physical Meteorology deals with the formation of cloud, rain and thunderstorm. The studying of law that governs the motion of the atmosphere is called Dynamical Meteorology, while Synoptic Meteorology deals with the weather systems on day to day bases.
Meteorologists are scientists who study meteorology. The best known application of this knowledge is forecasting the weather. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location.
Climate describes the average weather in a region. Climate represents the atmospheric conditions for a long period of time, and generally refers to the normal or mean course of the weather. The climate of a locality is the synthesis of the day-to-day values of the meteorological elements that affect the locality. Climatic data are usually expressed in terms of an individual calendar month or season and are determined over a period (usually about 30 years) long enough to ensure that representative values for the month or season are obtained.
Land and sea areas, being so variable, react in many different ways to the atmosphere, which is constantly circulating in a state of dynamic activity. Weather is measured by thermometers, rain gauges, barometers, and other instruments, but the study of climate relies on statistics. Today, such statistics are handled efficiently by computers. A simple, long-term summary of weather changes, however, is still not a true picture of climate. To obtain this requires the analysis of daily, monthly, and yearly patterns.
