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). |
