Name 7 throes of instruments to measure
Temperature
Atmospheric pressure
Humidity
Wind direction
Wind speed
Precipitation
Sunshine
Temperature?
Temperature measures how hot or cold the air is.instrument=thermometer Isotherms are lines on a weather map that join places of equal temperature. unit of measurement is degrees Fahrenheit or degrees Celsius.
Atmospheric pressure?
Atmospheric pressure is the weight of the atmosphere pressing down on the Earth. Instrument-barograph.. lines on a weather map that show areas of equal atmospheric pressure are called isobebars
Wind direction
The direction from which the wind is coming can be measured. Insturement-wind vane Wind direction is shown using arrows on a map.
Humidity
Humidity is the amount of water vapour or moisture in the air. Warm air is able to hold more moisture than cold air.instrument-hygrometer. Humidity is shown on a weather map as a percentage.
Wind speed
The strength or speed of the wind can also be measured.instrument- anemometer. When the isobars are closer together on a weather map, the wind will be stronger. When they are further apart, the wind will be lighter.
Sunshine
Sunshine is when the sun’s rays reach the surface of the Earth.instrument-Campbell-Stokes sunshine recorder. The lines on a weather map showing areas of equal sunshine are called isohels.
