|---|---|
| Atmosphere | the envelope of gases surrounding the earth or another planet |
| Troposphere | the lowest region of the atmosphere, |
| Stratosphere | the layer of the earth's atmosphere above the troposphere |
| Exosphere | the outermost region of a planet's atmosphere |
| Thermosphere | the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. |
| Exosphere | the outermost region of a planet's atmosphere. |
| Oxygen | a colorless, odorless reactive gas |
| Nitrogen | the chemical element of atomic number 7 |
| Argon | the chemical element of atomic number 18 |
| Trace Gases | A trace gas makes up less than 1% by volume of a planet's atmosphere |
| Water Vapor | water in a vaporous form especially when below boiling temperature and diffused |
| Air Pressure | the force exerted by air, whether compressed or unconfined, on any surface in contact with it. |
| Mercury Barometer | an instrument used for measuring the change in atmospheric pressure |
| Low Pressure | a condition of the atmosphere in which the pressure is below average |
| Aneroid Barometer | a device for measuring atmospheric pressure without the use of fluids |
| High Pressure | a condition of the atmosphere in which the pressure is above average |
| Thermal Energy | to the energy contained within a system that is responsible for its temperature |
| Convection | the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity |
| Jet Stream | a narrow variable band of very strong predominantly westerly |
| Coriolis Effect | an effect whereby a mass moving in a rotating system experiences a force |
| Global Winds | Global winds are one such type of wind |
| Trade Winds | a wind blowing steadily towards the equator from the northeast in the northern hemisphere or the southeast in the southern hemisphere, especially at sea |
| Westerlies | the belt of prevailing westerly winds in the mid-latitudes of the northern and southern hemispheres. |
| Polar Easterlies | the dry, cold prevailing winds that blow around the high-pressure areas of the polar highs at |
| The Doldrums | a state or period of inactivity, stagnation, or depression |
| Horse Latitudes | a belt of calm air and sea occurring in both the northern and southern hemispheres between the trade winds and the westerlies |
| Local Wind Patterns | winds that blow over a limited area. |
| Sea Breeze | a breeze blowing toward the land from the sea, especially during the day owing to the relative warmth of the land. |
| Land Breeze | a breeze blowing toward the sea from the land, especially at night, owing to the relative warmth of the sea |
| Water Cycle | he cycle of processes by which water circulates between the earth's oceans, |
| Evaporate | turn from liquid into vapor. |
| Condensation | water which collects as droplets on a cold surface when humid air is in contact with it |
| Runoff | a further competition, election, race, etc., after a tie or inconclusive result |
| Meteorologist | an expert in or student of meteorology; a weather forecaster. |
| Cirrus | cloud forming wispy filamentous tufted streaks |
| Stratus | Stratus |
| Nimbus | a luminous cloud or a halo surrounding a supernatural being or a saint. |
| Cumulus | cloud forming rounded masses heaped on each other above a flat base at fairly low altitude. |
| Air Mass | a body of air with horizontally uniform temperature, humidity, and pressure. |
| Weather | the state of the atmosphere at a place and time as regards heat |
| Climate | the weather conditions prevailing in an area in general or over a long period. |
| Forecast | predict or estimate |
| Temperature | measure of hotness or coldness expressed in terms of any of |
| Front | the side or part of an object that presents itself to view or that is normally seen or used first |
| Humidity | the state or quality of being humid |
| High Pressure System | ow-pressure systems. Low-pressure systems |
| Low Pressure System | suck" air into them because nature wants everything to have equal pressure. |
| Storms | a violent disturbance of the atmosphere with strong winds and usually rain |
| Precipitation | the action or process of precipitating a substance from a solution |
| Tornado | a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system. |
| thunderstorm | a storm with thunder and lightning and typically also heavy rain or hail. |
| Hurricane | a storm with a violent wind, in particular a tropical cyclone in the Caribbean |
| Flood | an overflowing of a large amount of water beyond its normal confines |
| Winter Storms | a combination of blowing snow and wind resulting in very low visibilities |
| Cumulonimbus Clouds | An extremely dense, vertically developed cloud with a low, dark base and fluffy masses |
