Question | Answer |
---|---|
Particulates | Solid particles in the air, such as dust, salt or ash |
Air Pressure | The pressure exerted on a surface by the weight o the atmosphere above the surface. Normally in mb (millibars) |
Density | The amount of mass per unit volume of a substance |
Humidity | The amount of water vapor in the air. High humidity increases the chances of clouds and precipitation. |
Climate | The long term average of weather in a particular place that is usually stable and changes slowly |
Weather | Description of what the atmosphere is like at a particular time and place. |
Cirrus | High, thin wispy clouds |
Cumulus | puffy, fluffy cotton looking clouds |
Cumulonimbus | vertical development clouds with precipitation |
Stratus | usually dark, lower level clouds that found in layers (Can produce rain) |
Air Mass | A large body of air that has the same conditions throughout |
Warm Front | The type of front that occurs when advancing warm air displaces cold air along a gradual slope; represented by evenly spaced red half circles on a weather. |
Cold Front | The type of front that occurs when cold dense air forces less dense warm air upward along a steep slope; represented by blue triangles pointing the direction the front is moving on a weather map. |
Stationary Front | The front that occurs when two air masses that have similar temperatures and pressures meet and neither advances; shown by a line with alternating red half circles and blue triangles facing in opposite directions on a weather map. |
Occluded Front | The type of front that occurs when a cold front overtakes a warm front and forces it upward causing the advancing cold air to collide with another cold air mass; shown on a weather map by alternating, evenly spaced, purple half circles and triangles. |
Maritime Airmass | Describes a moist airmass that originates over a body of water |
Continental Airmass | Describes a dry airmass that originates over land |
Tropical Airmass | Warm airmass that originates over the warm waters of the tropics and Pacific Ocean south of California |
Polar Airmass | Cold airmass that originates over Canada |
Arctic Airmass | Extremely cold and dry air masses that are created over land at very hight latitudes. |
