There are several instruments used to predict the weather in most cases, but the ones that determine whether there will or will not be rain are:
A flute is a musical instrument that is also the name for a type of cumulus cloud.
There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Also, unless cloud passes over them they give a false negative. The best instrument for measuring cloud cover is a trained Mark I eyeball (or two)Read more: What_instrument_is_used_to_measure_clouds
Yes, a seismograph is a type of technology used to detect and record earthquakes. It measures the motion of the ground caused by seismic waves generated by earthquakes or other sources of seismic energy.
A rain gauge measures in inches because it collects and measures the amount of precipitation that has fallen in an area.
psychrometer
Sluonameter is used to determine the cloud conditions in the sky.
A nephoscope is an instrument used to measure the height, direction, and velocity of clouds. It works by reflecting sunlight off the cloud and measuring the angles of reflection to determine cloud characteristics.
A flute is a musical instrument that is also the name for a type of cumulus cloud.
A galvanometer is a type of ammeter: An instrument for detecting and measuring electric current.
This instrument is a balance.
An instrument that measures heat and cold is called a thermometer.
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
An anemometer is the instrument that measures wind direction using a wind vane.
guitar
the simplest way to measure the curved lines is by using a thread...........or cloth type tape
A pyrometer is an instrument that measures very high temperatures, typically using infrared radiation to determine the heat emitted by an object. These devices are commonly used in industrial settings, such as in foundries, kilns, and furnaces, where traditional thermometers would be impractical or inaccurate.
A thermometer measures molecular energy.
