The word " meteorology " is from Greek μετέωρος , metéōros , "high in the sky"; and -λογία , -logia . Contents 1 History 1.1 Research of visual atmospheric phenomena 1.2 Instruments and classification scales 1.3 Atmospheric composition research 1.4 Research

The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences . The most notable advancements in observational meteorology , weather forecasting , climatology , atmospheric chemistry , and atmospheric physics are listed chronologically

Once an all-human endeavor based mainly upon changes in barometric pressure , current weather conditions, and sky condition, forecast models are now used to determine future conditions. Human input is still required to pick the best possible forecast model to base the forecast upon, which

The devices to measure these three sprang up in the mid-15th century and were respectively the rain gauge , the anemometer , and the hygrometer . The 17th century saw the development of the barometer and the Galileo thermometer , while the 18th century saw the development of the thermometer

The global warming controversy is a variety of disputes regarding the nature, causes, and consequences of global warming . The disputed issues include the causes of increased global average air temperature , especially since the mid-20th century, whether this warming trend is unprecedented

A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones feed on heat released when moist air rises, resulting in condensation of water vapor contained in the moist air. They

Weather occurs due to density (temperature and moisture) differences between one place and another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to

In meteorology , winds are often referred to according to their strength, and the direction the wind is blowing from . Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls . Long-duration winds have various names associated

Extratropical cyclones encompass a class of storms with many names. Although they are sometimes referred to as " cyclones ", this is imprecise; cyclone applies to numerous types of low pressure areas. The descriptor extratropical signifies that this type of cyclone generally occurs outside

In meteorology , a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth [ 1 ] [ 2 ] . This is usually characterized by inward spiraling winds that rotate counter clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of
