Meteorology is one of the sciences that study the Earth’s atmosphere, which focuses on the study of atmospheric processes and the weather forecast. The study of phenomena that occur in the atmosphere and the interactions between their dynamic, physical and chemical States, with the underlying land surface.
The studies in the field of meteorology were started more than two millennia, but only from the 17TH century the meteorology has progressed significantly. In the following century, the development of meteorology won even more significant impetus to the development of networks of exchange of data in many countries. With the highest efficiency in the observation of atmosphere and a more rapid exchange of meteorological data, the first numerical weather predictions became possible with the development of meteorological models in the early 20th century. The invention of the computer and the Internet has made it faster and more efficient processing and exchange of meteorological data, thus providing a greater understanding of meteorological events and their variables and, therefore, made possible a more precise forecast.
The word “meteorology” comes from the Greek μετέωρος metéōros “; high (in the sky) “(from μετα-meta-” above “and ἀείρω aeiro” I get up “) and-λογία-logia” study, word “.
The focus of study of Meteorology is the investigation of the observable phenomena related to the atmosphere. The atmospheric events are observable only in a broad period of time are the focus of study of climatology. Meteorological phenomena are related to variables that exist in the atmosphere, which are mainly temperature, atmospheric pressure and air humidity, their relationships and their variations over time. Most weather events occurs in the troposphere, the lowest layer of the Earth’s atmosphere, and can affect the planet Earth as a whole or affect only a small region, and that meteorology is subdivided to better study the meteorological events on a global scale, or purely local events.
Meteorology is part of a set of atmospheric sciences. Part of the climatology, atmospheric physics, which aims at applications of Physics in the atmosphere, and atmospheric chemistry, which studies the effects of chemical reactions resulting in the atmosphere. Meteorology itself can become an interdisciplinary science when merges, for example, with the hydrology, Hydrometeorology, becoming that studies the behavior of rainfall in a particular region, or you can merge with Oceanography, becoming the maritime meteorology, aimed at the study of the relationship of the oceans to the atmosphere.
The applications of meteorology are quite large. The planning of agriculture is dependent on meteorology. Energy policy of a country dependent on its water catchment area can also depend on meteorology. Military strategies and construction also depend on the weather, and weather influences the daily life of the whole society.
