A weather thermometer measure the surrounding outside or inside air temperature. The thermometer, which is a device composed of a long tube with a fluid in it, is enclosed in a glass rod. The fluid inside the tube can be either colored alcohol or mercury.Continue Reading
The thermometer can use either a Fahrenheit or a Celsius scale to measure temperature. As the temperature rises, the liquid moves up the tube and markings on the glass tube of the thermometer gives the temperature reading. When it is cold, the liquid inside the tube moves down accordingly.
Although most people are familiar with the enclosed tube thermometer, there are other types of thermometers like the U-shaped one that measures the maximum and minimum temperatures over a period of time.Learn more about Weather & Tides
Conduction, along with radiation and convection, are the causes for changes in the temperature, which also causes the change in the weather. Conduction plays a very small role in weather as the process is mostly reliant on convection, which explains the movement of warm air and how it rises.Full Answer >
The weather changes due to factors like gravity, sunlight, topography, oceans and the movement of air affecting the atmosphere. The atmosphere can be changed through several forces that are both terrestrial and extraterrestrial.Full Answer >
Changes in weather are the result of air masses of different temperatures and pressures reacting, influenced by the terrain. Two main types of weather systems exist: high pressure and low pressure. High-pressure systems are associated with sinking air, while low-pressure systems are associated with rising air.Full Answer >
A Chinook wind is a weather phenomenon that creates warm, dry air that blows down the eastern slopes of the Canadian Rockies. The name Chinook means "snow eater," as the wind occurs most frequently in winter and can disrupt snowstorms and melt fallen snow.Full Answer >
