Question

What are some measurement devices we use to describe the weather?

Answer 1

Hint: Weather refers to the state of the atmosphere, such as how hot or cold it is, how wet or dry it is, how quiet or stormy it is, and how clear or foggy it is. The troposphere is the lowest layer of the planet's atmosphere, just below the stratosphere, where most meteorological occurrences occur.

Complete answer:
The following are some of the most regularly used tools for monitoring atmospheric conditions
i) Transmissometer: Transmissometer is a device that measures the degree of attenuation of a light beam as it travels through water or air at a specific distance (typically between a few meters and 150 meters). The tools then make an impartial assessment of current viability based on this information.

ii) Stevenson screen: A Stevenson screen is a box constructed of two layers of screens that are used to protect meteorological instruments from precipitation or direct heat radiation from outside sources. This enclosure allows air to flow freely around the temperature and humidity sensors. The Stevenson screens are typically painted white to reflect the sun's rays.

iii) Barometer: A barometer is a device used to determine atmospheric pressure. The rising of warm air and the descent of cold air are the main causes of changes in atmospheric pressure. The local weather affects the barometric pressure. Good weather is associated with rising pressure, while bad weather is associated with lowering pressure.

iv) Lidar: Lidar is a distance-measuring technique that may also be used to collect information about distant objects. The target is illuminated with a laser, and the reflected light is then evaluated. In meteorology, the Lidar is used to profile clouds, monitor winds, investigate particles, and quantify numerous atmospheric constituents, among other things.

v) Anemometers: Anemometers are instruments used to measure wind speed. Initially, they were primarily employed to measure wind speed and direction. They are now commonly employed in estimating the average speed in ventilation systems established in industrial and residential buildings, aside from weather stations.

vi) Rain gauge: A rain gauge is a device that measures the amount of precipitation that has fallen over some time. Every weather station includes a rain gauge. It is used in meteorology as an additional tool for weather forecasting and climatology for long-term precipitation statistics.

Note: Climate refers to the averaging of atmospheric conditions over longer periods, whereas weather relates to day-to-day temperature, precipitation, and other atmospheric factors. "Weather" is commonly understood to refer to the weather on Earth when used without qualification.
