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 >
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 >
Austin, Texas, stays fairly warm throughout the year — even during the winter months. No month has an average low temperature that dips lower than 40 degrees Fahrenheit, and the average high temperature for any month is never lower than 62 degrees Fahrenheit.Full Answer >
