What are the different kinds of meteorological instruments and what do they measure?

Anemometer: this instrument measures both the wind speed and direction.

Barometer: measures the atmospheric pressure.

Ceilometer: measures the base of the cloud height.

Hygrometer: measures the humidity of the air.

Rain-gauge: measures the amount of precipitation.

Sunshine recorder: measures the duration of sunshine.

Stevenson-screen: A type of wooden louvered rectangular box which houses maximum and minimum (centre) and wet and dry bulb thermometers.

What do all those weather terms mean?

Anticyclone: Region of the atmosphere where the pressures are high relative to those in the surrounding region at the same level.

Depression: Region of the atmosphere in which the pressures are lower than those of the surrounding region at the same level. This is the opposite of an Anticyclone.

Cyclone:A severe type of tropical storm with very low atmospheric pressure at the centre and strong winds blowing around it.

Gulf Stream: A current of warm surface ocean water in the North Atlantic flowing from the Gulf of Mexico towards northwest Europe. It has an important influence in maintaining relatively mild winters in Ireland.

hectoPascal: Unit of pressure, equivalent to a Millibar.

Isobar: Line joining points of equal pressure

Isohyet: Line joining points of equal precipitation amount recorded during a specific period.

Isotach: Line joining points of equal wind speed

Isotherm: Line joining points of equal air temperature.
