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.Know More
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
Weather patterns on Earth are driven by the unequal heating of the surface by sunlight. The Sun is the ultimate source of energy that drives wind, rain and storms across the planet. The movement of wind patterns, ocean currents and even the water cycle can all be thought of as global mechanisms for redistributing heat from the Sun.Full Answer >
Weather is triggered by differences in air pressure (temperature and moisture) between one location and another. Global weather is highly dynamic and is determined by air currents in the atmosphere.Full Answer >
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 >
A barometer is a device used for measuring atmospheric pressure, also known as barometric pressure or air pressure. A mercury barometer does this by balancing the weight of mercury contained in a glass tube against the weight of the air in the surrounding atmosphere.Full Answer >
