Weather Flashcards
Dew point
temperature to which air must be cooled to become saturated (full) with water vapor(gas).
Climate
average weather pattern in an area over a long period of time (temperature, humidity, precipitation, and vegetation), 30 years plus!
Weather
The conditions outside in the atmosphere at a particular place and time (may change second to second, day to day, week to week, month to month).
Precipitation
water,rain, sleet, snow, hail, and mist, that falls to Earth’s surface.
Air Mass
a large body of air that is similar in temperature, humidity, and air pressure throughout.
Air pressure
the force of air on a surface
Warm front
the boundary between an advancing mass of relatively warm air and a mass of colder air.
Cold front
the boundary between an advancing mass of relatively cold air and a mass of warmer air, the cold air acts like a plow forcing the warm air up.
High pressure system
a region in which the atmospheric pressure is higher than in the surrounding areas.
Low pressure system
a region in which the atmospheric pressure is lower than in the surrounding areas.
Coriolis Effect
The invisible force that deflects fluids (gas/liquids), in the Northern Hemisphere to the right and in the Southern Hemisphere to the left. The impact of this Coriolis Effect is dependent on the velocity (speed and direction) and the fluid being deflected.
