METEOROLOGY: Weather
Fifth Grade!
| Term | Definition |
|---|---|
| Wind Speed | is the speed of wind, the movement of air or other gases in an atmosphere |
| Wind Direction | the direction from which the wind is blowing, measured using a wind vane |
| Precipitation | any form of water, such as rain, snow, sleet, or hail, that falls to the earth's surface and the quantity of the amount |
| Temperature | measure of the warmness or coolness of an object, measured using a thermometer |
| Air Pressure | the pressure exerted by the atmosphere, measured using a barometer |
| Climate | the average condition of atmosphere over a long period of time |
| Weather | state of the atmosphere at a given time and place |
| Atmosphere | the layer of gases that surround the Earth and are locked in, or trapped, by the Earth's gravitational pull |
| Stratus Clouds | clouds that form in blanket-like layers at low altitudes |
| Cirrus Clouds | clouds that form at very high altitudes out of ice crystals and have a wispy, featherlike shape. |
| Cumulus Clouds | puffy clouds that appear to rise up from a flat bottom. |
| Nimbus Clouds | A cloud that already had a form of precipitation falling from it |
| Meteorology | the study of the atmosphere and weather |
| Forecast | prediction of the upcoming weather conditions for a given area at a given time |
| High Pressure System | a pattern surrounding a high pressure center from which winds blow outward |
| Low Pressure System | a pattern surrounding a low pressure center in which winds blow in toward the center |
| Warm Front | Forms when a moist, warm air mass slides up and over a cold air mass, causing gentle precipitation and warm, mild weather. |
| Cold Front | Forms when a cold air mass pushes under a warm air mass, forcing the warm air to rise, causing thunderstorms and cool, fair weather afterwards. |
| Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” This front causes many days of rainy/cloudy weather and/or fog. | Stationary Front |
| Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle, causing cold temperatures, strong winds, and heavy precipitation. | Occluded Front |
| a tool for measuring the air pressure of an area | Barometer |
| measures temperature of an area in the units of Celsius of Farhenheit | Thermometer |
| a tool used to measure wind speed in the units of ft/min, m/s, MPH, km/h and knots to accommodate a wide variety of uses. | Anemometer |
| Wind Vane | a tool used to find the wind direction, directions include N, S, E, W, NE, NW, SE, SW (rooster) |
| Rain Gauge | a tool used to measure the amount of precipitation over a specific period of time in liters |
| Hygrometer | a tool for measuring the humidity of an area |
| amount of water vapor in the air | Humidity |
| A very strong low pressure storm system with violent wind. These storms usually start over the Atlantic Ocean in the tropics. | Hurricane |
| Evaporation | the process in which a liquid turns in to a gas, water becomes water vapor. (gaining energy) |
