Glossary: Temperature

Temperature

Temperature is the degree of hotness or coldness. Air temperatures are influenced by the local landscape, such as the presence of bodies of water. The air temperature is measured in degrees Celsius and is rounded to the nearest degree. The daytime maximum and nighttime minimum temperatures that a forecaster expects are often expressed as a range. If the forecast issued covers a wide region, the highs and lows are not going to be identical across all areas in that region.
