Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics, with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century. Meteorology is a branch of atmospheric science that includes atmospheric chemistry and atmospheric physics, with a major focus on weather forecasting. The study of meteorology dates back to the 18th century, when significant advances in meteorology did not occur. Large regions of meteorological observation networks of the 19th century saw modest progress. Previous attempts to forecast the weather dependent on weather data. It is only after the laws of physics and more advanced development of the computer, a large number of equations of the automated solution, that the model forecasts that the second half of the 20th century is the sign of the weather forecast. have been made An important area of ​​weather forecasting is the large ones with atmospheric interactions, including coordinating maritime and coastal security, which include weather effects. Weather phenomena are observable weather events that are explained by the science of meteorology. Meteorological phenomena are described and quantified by the Earth's atmosphere: temperature, atmospheric pressure, water vapor, mass flow, and variations and interactions of these variables, and how they change over time.
