Weather Watch

a huge body of air that has similar temperatures, humidity, and air pressure at any given height air mass
the pressure caused by the weight of a column of air pushing down on an area air pressure
elevation above sea level altitude
an instrument used to measure wind speed anemometer
a high pressure center of dry air anticyclone
an instrument used to measure changes in air pressure barometer
wispy, feathery clouds made of ice crystals that form at high levels cirrus
the average, year after year, conditions of temperature, precipitation, winds, and clouds in an area climate
a dry air mass that forms over land continental air mass
the change that Earth's rotation causes in the motion of objects and that explains how winds curve coriolis effect
fluffy, white clouds, usually with flat bottoms that look like rounded piles of cotton cumulus
a swirling center of low pressure cyclone
the temperature at which condensation begins dew point
long periods of low precipitation droughts
the boundary where unlike air masses meet but do not mix front
winds that blow steadily from specific directions over long distances global winds
the amount of water vapor in a given volume of air humidity
a tropical storm that has winds of about 119 kilometers per hour or higher hurricane
a line on a weather map that joins places that have the same air pressure isobar
a line on a weather map that joins places that have the same temperatures isotherm
bands of high speed winds about 10 kilometers above the Earth's surface jet streams
the flow of air from land to a body of water land breeze
a sudden spark, or energy discharge, caused when electrical charges jump between parts of a cloud, between nearby clouds, or between a cloud and the ground lightning
winds that blow over short distances local winds
a humid air mass that forms over oceans maritime air mass
scientists who study the causes of weather and try to predict it meteorologists
cut off, as in a front where a war air mass is caught between two cooler air masses occluded
a cold air mass that forms north of 50 degrees north latitude or south of 50 degrees south latitude and has high pressure polar air mass
the amount of force pushing on an area pressure
an instrument used to measure precipitation rain gauge
the percentage of water vapor in the air relative to the maximum amount of water vapor that air can contain at a particular temperature relative humidity
the flow of cooler air from an ocean or lake toward land sea breeze
a violent disturbance in the atmosphere storm
clouds that form in flat layer and often cover much of the sky stratus
a measure of how hot or cold an object is compared to a reference point temperature
an instrument used to measure temperature thermometer
a small storm often accompanied by heavy precipitation and frequent thunder and lightning thuderstorm
a rapidly, whirling funnel-shaped cloud that reaches sown to touch Earth's surface tornado
a warm air mass that forms in the tropics and has low air pressure tropical air mass
the condition of Earth's atmosphere at a particular time and place weather
the horizontal movement of air from an area of high pressure to an area of lower pressure wind
a measure of cooling combining temperature and wind speed wind chill factor
an instrument used to measure relative humidity psychrometer
