Meteorologyis a branch of theatmospheric scienceswhich includesatmospheric chemistryandatmospheric physics, with a major focus onweather forecasting. The study of meteorology dates backmillennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw modest progress in the field afterweather observationnetworks were formed across broad regions. Prior attempts atprediction of weatherdepended on historical data. It was not until after the elucidation of thelaws of physicsand more particularly, the development of the computer, allowing for the automated solution of a great many equations that model the weather, in the latter half of the 20th century that significant breakthroughs in weather forecasting were achieved. An important domain of weather forecasting ismarine weather forecastingas it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.
Meteorological phenomenaare observable weather events that are explained by the science of meteorology. Meteorological phenomena are described and quantified by the variables ofEarth's atmosphere:temperature,air pressure,water vapour,mass flow, and the variations and interactions of those variables, and how they change over time. Differentspatial scalesare used to describe and predict weather on local, regional, and global levels.
Meteorology,climatology,atmospheric physics, andatmospheric chemistryare sub-disciplines of theatmospheric sciences. Meteorology andhydrologycompose the interdisciplinary field ofhydrometeorology. The interactions between Earth's atmosphere and its oceans are part of a coupled ocean-atmosphere system. Meteorology has application in many diverse fields such as themilitary,energy production,transport,agriculture, andconstruction.
Nottinghamshire (pronounced /ˈnɒtɪŋəmʃər, -ʃɪər/; abbreviated Notts.) is a county in the East Midlands region of England, bordering South Yorkshire to the north-west, Lincolnshire to the east, Leicestershire to the south, and Derbyshire to the west. The traditional county town is Nottingham, though the county council is based at County Hall in West Bridgford in the borough of Rushcliffe, at a site facing Nottingham over the River Trent.
The districts of Nottinghamshire are Ashfield, Bassetlaw, Broxtowe, Gedling, Mansfield, Newark and Sherwood, and Rushcliffe. The City of Nottingham was administratively part of Nottinghamshire between 1974 and 1998, but is now a unitary authority, remaining part of Nottinghamshire for ceremonial purposes.
In 2017, the county was estimated to have a population of 785,800. Over half of the population of the county live in the Greater Nottingham conurbation (which continues into Derbyshire). The conurbation has a population of about 650,000, though less than half live within the city boundaries.
