What is air temperature? Air temperature is a measure of how hot or cold the air is.Temperature is measured using thermometers. It is often the first thing you read in a weather report, and can help you decide what clothes to wear, what activities to plan, and what gear to bring when heading outside.
Air temperature is a measure of the amount of energy held in the air. Warm air has more internal energy than cooler air. Temperature can be reported using several different scales. In the United States, the Fahrenheit scale is the most common. Internationally and in science, people use the Celsius scale. Just like other regions of the Earth, temperatures in the Arctic tend to rise during the day, when sunlight warms the ground, and fall at night. Arctic temperatures are warmer in summer, when there is more sunlight, and colder in winter, when the region is dark. Scientists also use temperature for monitoring changes in climate. Long-term measurements of air temperatures over many years are important for scientists to track climate change.
How does Air temperature influence weather?
The most basic thing to understand is that warm air wants to rise while cold air wants to sink. Hot air contains fewer molecules per cubic meter while cold air contains more, hence the warm air will rise up over colder air. The most common example of this is the existence of a hot or cold front. These fronts are simply boundaries between hot and cold air. As the temperature of a substance increases,the particles in the substance move faster causing lower density and lower pressure. As the temperature of a substance decreases the particles in the substance move slower causing higher density and higher pressure.
