| Question | Answer |
|---|---|
| What is a huge body of air that covers thousands of square km, uniform temp | air mass |
| regional wind system that reverses periodically bringing wet and dry seasions | monsoon |
| a line of violent thunderstorms sometimes come witha a cold front | squall line |
| a region with a somewhat uniform temperature and humitity over which air masses form | source region |
| an air mass that is warmer than the surface over whick it moves | warm air mass |
| an air mass that is colder that the surface over which it moves | cold air mass |
| a sone of contact between 2 disimaliar air masses where niether is advancing | stationary front |
| a front formed when a cold air mass and a rapidly moving cold air mass trap an warm air mass between them | occluded front |
| pressure gradient force | |
| a high-altitude wind that is cotrolled by the relative influence of the pressure gradient force and the coriolis effect | geostrophic wind |
| a weather system centered on a low pressure area surrounded by a wind circulation patters spiraling counterclockwise in the northern hemisphere and clockwise in the southern hemisphere | cyclone |
| an area of relativl higher atmosphereic pressure | anticyclone |
| a high speed meandering wind current usually flowing from the west to the east at altitudes of 15 to 25 km. | jet stream |
| a breese that blows onshore from the ocean, usually during the day time | sea breeze |
| a breeze that blows from the shore to the sea | land breeze |
| a breeze that flows op the mountainside from the valley when air high on a mountain heats an risees and occurs late in the day | valley breeze |
| a breeze that flows down the mountain into the valley at night that is cause | mountain breeze |
| winds extending from the subtropical highs toward the equator | trade winds |
| winds blowin consistantly from southeast to northeast between 30 and 60 degrees north and south lattitudes | prevailing westerlies |
| winds that blow consistantly from the northeast to the southwest from the northern polar region | polar easterlies |
| a perminet low pressure belt on usually windless air near the equator caused by the vertical rising of warm air | doldrums |
| a band of perminetly high pressure caused by decending cold air. | horse latitudes |
| the prevailing low pressure belt at 60 degrees north and south latitude. | subpolar low |
| an area of high atmosphericpressure at either pole caused by subsiding cold air | polar high |
| a rainstorm that includes lighting and thunder | thunderstorm |
| a towering cumulonimbus cloud that builds rapidly to high altitudes | thunderhead |
| an electrical discharge that occurs either between clouds or between a cloud and the grounds | lightning |
| a zigzig column of highly ionized air that establishes the channel for lightning discharges and | stepped leader |
