A device that measures the direction of the wind. It spins on a rod and points in the direction from which the wind blows. The part of the vane that turns into the wind is usually shaped like an arrow.

A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries. Barometers and pressure altimeters the most basic and common type of altimeter are essentially the same instrument, but used for different purposes. An altimeter is intended to be transported from place to place matching the atmospheric pressure to the corresponding altitude, while a barometer is kept stationary and measures subtle pressure changes caused by weather. The main exception to this is ships at sea, which can use a barometer because their elevation does not change.

Weather Elements and Instruments Used for Measurement

A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature , atmospheric pressure , humidity , wind speed , wind direction , and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature SST , wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. In addition, at certain automated airport weather stations , additional instruments may be employed, including:.

Until the 18 th century, people were utterly dependent on sensory observations for any weather data, i. Now, the time has changed. Today, we are blessed by modern technology which includes different weather instruments that help us to accumulate accurate weather data. Meteorology is the science of atmosphere that includes both the weather and the climate. This study includes some methodological instruments that help to collect physical, dynamic and chemical state of the atmosphere. Here, I am going to give a clear concept about some most important meteorological or weather instruments and their usage that will make you realize how blessed we are because of these instruments and how they help to collect accurate weather data. There are different types of instruments for measuring different parameters.

Meteorologists use a wide variety of different instruments to measure weather conditions, but many of these instruments fall into relatively common, overarching categories. Thermometers, for instance, come in traditional liquid-in-glass forms and newer electronic forms, but both measure temperature in Celsius and Fahrenheit. Other instruments measure aspects of weather like rainfall, pressure, humidity and wind speed. These instruments and measurements allow meteorologists to make predictions on weather conditions in the near future. Thermometers measure the high and low outdoor temperatures in degrees Fahrenheit and degrees Celsius. Meteorologists first used liquid-in-glass thermometers in the late s, but they now use electronic maximum-minimum temperature sensor systems more frequently. The newer systems use an electronic temperature sensor to measure and record high and low temperatures.

Weather station

Weather instruments are used to take measurements of various atmospheric parameters at local weather stations. Why do I care? By understanding patterns of temperature, wind, and rainfall as measured by instruments, we can describe our local weather and climate. Weather instruments are used to take measurements of temperature, wind, humidity, and rainfall, as well as other atmospheric factors which describe the local weather and climate.
