Question | Answer |
The 4 main types of precipitation | rain, snow, sleet, hail |
______________ variations within clouds and/or within the region between the cloud and Earth determines the various forms of precipitation | temperature |
Clouds form as a result of _________ | condensation |
Clouds that form from the condensation of water vapor are classified by a ________ and __________ | shape & height |
The 3 major classifications of clouds | cumulus, cirrus, and stratus |
_________ clouds are formed at medium to low elevations, and are puffy with flat bottoms. | cumulus |
Cumulus clouds that are white signal _____ weather, but when they are darker in color, they may signal ________. | fair, rain |
________ clouds are formed at high elevations, are wispy, and consist of ice crystals. | cirrus |
Cirrus clouds usually signal _________ weather or an approaching _______ front. | fair, warm |
________ clouds form at medium or low elevation, are layered and cover a large area. | stratus |
Stratus clouds usually bring long periods of steady ______________. | precipitation |
Nimbus means _______ ___________ cloud. | rain bearing |
The prefix alto refers to clouds at __________ elevation. | medium |
Fog is an example of a ________ cloud that forms near the ground. | stratus |
_____ forms when drops of water fall in temperatures above freezing. | rain |
_____ forms when the air temperature is so cold that water vapor changes directly to a solid. | snow |
_____ forms when raindrops pass through a layer of freezing air near Earth's surface. | sleet |
_____ forms in cumulonimbus clouds when water freezes in layers as the ice nucleus is tossed up and down within the cloud. | hail |
The 3 things that determine various weather conditions | air masses, fronts, and pressure systems |
____ _________ are huge bodies of air that form over water or land in tropical or polar regions. | air masses |
_____ ________ can form with cool/moist air, cold/dry air, warm/moist air, or hot/dry air based on where they form. | air masses |
_____ form at the boundaries between air masses. | Fronts |
The 4 types of fronts | warm, cold, stationary, and occluded |
When a warm air mass collides and rides over a cold air mass, the resulting _____ front may produce long periods of precipitation and warmer temperatures. | warm |
When a cold air mass collides and slides under a warm air mass, the resulting _____ front may produce thunderstorms and sometimes tornadoes and cooler temperatures. | cold |
When neither a cold air mass nor a warm air mass moves at a frontal boundary, the resulting ________ front may produce long period of precipitation. | stationary |
When a cold air mass pushes into a warm air mass that is behind a cool air mass, the warm air mass is pushed up above the cooler air masses. The resulting ______ front may produce long periods of precipitation. | occluded |
______ _________ systems usually signal more fair weather with winds circulating around the system in a clockwise direction. | High pressure |
______ _________ systems with counterclockwise circulating winds often result in rainy and/or stormy weather conditions. | Low pressure |
Severe weather conditions called _______ occur when pressure differences cause rapid air movement. | storms |
A storm with heavy rains and strong winds that form within cumulonimbus clouds along a cold front or within an air mass. | Thunderstorm |
A very low pressure system with a rapidly whirling, funnel shaped cloud that extends down from a storm cloud. | Tornado |
A low pressure tropical storm that forms over warm ocean water with winds that form a spinning circular pattern around the center, or eye, of the storm. | Hurricane |
A tool used to measure wind speed in miles per hour. | anemometer |
A tool used to measure wind direction. | wind vane |
A tool used to measure air temperature in degrees Fahrenheit or Celsius. | thermometer |
A two-thermometer instrument also referred to as a wet-dry bulb used to measure relative humidity. | psychrometer |
The amount of water vapor in the air compared to the amount needed for saturation at a specific temperature. | relative humidity |
A tool used to measure air pressure in inches of mercury or millibars(mb). | barometer |
A tool used for measuring the amount of precipitation in inches or centimeters. | rain gauge |
_________ _____ can help predict weather patterns by indicating high or low pressure systems (isobars), movement of air masses and fronts, or temperature ranges (isotherms). | Weather maps |
_______ _________ provide information from specific locations that can also be used to predict weather patterns. | station models |
