Rain Gauge Experiment: Here is an experiment that allows a kids to make their very own rain gauge. Weather Instrument Activities Thermometer Experiment: Here is a great experiment that allows the kids to make a thermometer. This radar produces many different views of storms and rain that allows meteorologists to determine if a storm could be severe. The National Weather Service has installed a new type of Doppler Radar called NEXRAD Radar.
Doppler Radar measures the changes in the frequency of the signal it receives to determine the wind. This change in the frequency of sound is called the Doppler Effect. Have you ever listened to a train whistle as it was coming toward you? You probably noticed that the pitch of the whistle changed as the train passed you and moved away. Combined with satellites, radar gives forecasters the ultimate tools to provide accurate forecasts and advanced severe weather warnings.ĭoppler Radar gets its name from the Doppler Effect. Doppler Radar gives forecasters the capability of providing early detection of severe thunderstorms that may bring strong damaging winds, large hail, heavy rain, and possibly tornadoes. This is what meteorologists use to see rain or snow.ĭoppler Radar detects precipitation intensity, wind direction and speed, and provides estimates of hail size and rainfall amounts. It stands for Radio Detection and Ranging. Radar is an electronic instrument, which determines the direction and distance of objects that reflect radio energy back to the radar site. Always keep an eye at the sky and you’ll usually be on top of weather conditions. YOUR EYES are one of the best ways to help detect the weather. Then meteorologists compile and analyze the data with the help of computers. WEATHER SATELLITES are used to photograph and track large-scale air movements. Meteorologists use weather maps to forecast the weather.Ī HYGROMETER measures the water vapor content of air or the humidity.Ī WEATHER BALLOON measures weather conditions higher up in the atmosphere.Ī COMPASS is a navigational instrument for finding directions. WEATHER MAPS indicate atmospheric conditions above a large portion of the Earth’s surface. The dial shows the wind speed.Ī WIND SOCK is a conical textile tube, which resembles a giant sock, designed to indicate wind direction and relative wind speed. The cups catch the wind, turning a dial attached to the instrument. Water evaporates from the cloth, causing the temperatures on that thermometer to be lower than the other.Ī RAIN GAUGE measures the amount of rain that has fallen over a specific time period.Ī WIND VANE is an instrument that determines the direction from which the wind is blowing.Īn ANEMOMETER measures wind speed. Wet the cloth of one of the thermometers and swing the psychrometer around a few times.
Two thermometers are used in a sling psychrometer. An Italian scientist named Torricelli built the first barometer in 1643.Ī SLING PSYCHROMETER measures relative humidity, using the cooling effect of evaporation. A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions. It tells you whether or not the pressure is rising or falling. A scale then shows what the actual temperature is.Ī BAROMETER measures air pressure. When air around the tube heats the liquid, the liquid expands and moves up the tube. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. Educators earn digital badges that certify knowledge, skill, and experience.A THERMOMETER measures the air temperature.
