Weather
| Term | Definition |
|---|---|
| Clouds | a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground. |
| Condensation | the process where water vapor becomes liquid. |
| Cirrus Clouds | short, detached, hair-like clouds found at high altitudes. |
| Hygrometer | an instrument for measuring the humidity of the air or a gas. |
| Map | a drawing of the earth's surface, or part of that surface, showing the shape and position of different countries, political borders. |
| globe | the earth |
| Cumulonimbus | menacing looking multi-level clouds, extending high into the sky in towers or plumes. |
| Cirrocumulus | cloud forming a broken layer of small fleecy clouds at high altitude. |
| Stratocumulus | a layer of cloud clumps with thick and thin areas that cause rain or thunderstorms. |
| Cirrostratus | transparent high clouds, which cover large areas of the sky. |
| Nimbostratus | often dark-grey cloud that usually produces continuous rain, snow, or sleet, |
| Latitude | measures the distance north or south of the equator. |
| Longitude | the angular distance of a place east or west of the meridian |
| hemisphere, | a half of a sphere. |
| climate | the weather conditions prevailing in an area in general or over a long period. |
| Rain | moisture condensed from the atmosphere that falls visibly in separate drops. |
| Freezing rain | rain that freezes on impact with the ground or solid objects. |
| Sleet | a form of precipitation consisting of ice pellets, often mixed with rain or snow. |
| Snow | . atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer. |
| Wind | the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction. |
| Anemometer | an instrument for measuring the speed of the wind, or of any current of gas. |
| wind vane | an instrument that measures the direction from which the wind is blowing. |
| Cariolis effect | the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around Earth. |
| Trade winds | winds that reliably blow east to west just north and south of the equator. |
| Prevailing westerlies | average or normal westerly winds of the middle latitudes. |
| Polar easterlies | dry, cold prevailing winds that blow around the high-pressure areas of the polar highs at the North and South Poles. |
| Air pressure | the force exerted on a surface by the air above it as gravity pulls it to Earth. |
| Barometer | an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude. |
| Low pressure | A mass of warm rising moist air that generally bring stormy weather like rain, snow and strong winds. |
| High pressure | Mass of Cool dry air brings fair, dry weather, clear skys and light winds. This is caused by a rise in air pressure. |
| Cold front | forms when a cold, dense air mass pushes under a warm, lighter air mass, forcing the warm air to rise. |
| Warm front | clouds and storms. |
| Occluded front | forms when a warm air mass gets caught between two cold air masses. |
| Stationary front | warm air is present behind it (to its south) with cool air ahead of it (to its north). |
| Weather | the general condition of the atmosphere at a particular time and place, with regard to the temperature, moisture, cloudiness, etc. |
| Atmosphere | the envelope of gases surrounding the earth or another planet. |
| Cumulus | cloud forming rounded masses heaped on each other above a flat base at fairly low altitude. |
| Stratus | cloud forming rounded masses heaped on each other above a flat base at fairly low altitude. forming a continuous horizontal gray sheet, often with rain or snow. |
| Nimbus | the type of dense clouds or cloud mass with ragged edges, that yields rain or snow |
| Land Breeze | a local wind system characterized by a flow from land to water late at night. |
| Sea Breeze | a local wind system characterized by a flow from sea to land during the day. |
| Precipitation | a local wind system characterized by a flow from sea to land during the day. |
| Evaporation | the process of turning from liquid into vapor. |
| Jet Stream | a narrow variable band of very strong predominantly westerly air currents encircling the globe several miles above the earth. There are typically two or three jet streams in each of the northern and southern hemispheres. |
| Gulf Stream | The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude and moves toward Northwest Euro |
| Air Mass | a body of air with horizontally uniform temperature, humidity, and pressure. |
| La Nina | he periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific |
| Temperature | the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch. |
| Humidity | the amount of water vapor in the air. |
| Thermometer | an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with hea |
| Rain Gauge | a device for collecting and measuring the amount of rain which falls. |
| Front | a weather system that is the boundary separating two different types of air. |
| Hurricane | a storm with a violent wind, in particular a tropical cyclone in the Caribbean. |
