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.

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. Different types of instruments are used to measure different parameters and there are many types to choose from. A thermometer is an instrument used to measure temperature. Thermometers are used to measure outside and inside temperature, body temperature, oven temperature, and food temperature.

This article throws light upon the eight elements of climate measured by weather instruments. The elements are: 1. Rainfall 2. Pressure 3. Temperature 4.

Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is. It tells you whether or not the pressure is rising or falling. A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions. An Italian scientist named Torricelli built the first barometer in Two thermometers are used in a sling psychrometer.

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.

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.
