| cumulonimbus | type of cloud tornadoes and thunderstorms form in |
| sudden storms | type of storms which cause flash floods |
| rising air pressure | rain or snow associated with this type of air pressure |
| isobars | join places on a map that have the same air pressure |
| arid or semiarid | climate which occurs where precipitation is less than evaporation |
| climate | prevailing winds and mountains are the main factors which affect this of an area |
| cyclones | often associated with storms and precippitation due to decreasing air pressure |
| anticyclones | associated with increasing air pressure and fair weather |
| cumulonimbus | type of clouds thunderstorms form within |
| 75 km/hr | wind speed of a tropical storm to be classified as a hurricane |
| eye of the hurricane | part of a hurricane which is calm |
| eyewall | part of a hurricane which has the highest winds |
| melting snow and spring rains | flooding is often caused by these |
| small lines at the end of wind direction shaft | indicate the wind speed on a weather map |
| 70-80 percent cloud cover | percent of cloud cover represented by 3/4 black and 1/4 white cloud cover symbol |
| temperature and precipitation | two factors which determine the climate of a region |
| continental tropical air mass | type of air mass which develops over northern Mexico |
| maritime tropical air mass | warm humid air mass which affects the west coast of the United States |
| continental polar air mass | type of air mass which affects the northern United States in winter |
| cold front | type of front where rapidly moving cold air collides with a slowly moving warm air mass |
| tornado | funnel shaped cloud that touches Earth's surface |
| computer technology | advancement of this has improved weather forecasting |
| meteorologist | people who study weather and try to predict it |
| balloons and satellites | two types of technology which has improved collecting of data in the last 40 years |
| isotherms | lines on a weather map which join areas with the same temperature |
| stationary front | type of front which occurs when a warm and cold air mass meet and no movement occurs |
| warm front | type of front which occurs when a warm air mass collides with a cold air mass |
| to the left | direction of the wind in a cyclone in the Northern Hemisphere |
| to the right | direction of the wind in an anticyclone in the Northern Hemisphere |
| in the basement | best place to seek shelter in a tornado |
| move to higher ground | to protect yourself near flood waters you should to this |
| El Nino | abnormal weather pattern which occurs in the Pacific Ocean every 2 to 7 years |
| windward | side of a mountain which receives the most precipitation |
| leeward | side of a mountain which receives the least amount of precipitation |
| rain shadow | the leeward side of a mountain is in this since it has the least amount of precipitation |
| occluded front | type of front where a warm air mass is caught between two cooler air masses |
| anticyclone | from the center of a "high", the winds spiral outward in this |
| anticyclone | winds spiral outward |
| cyclone | winds spiral inward |
| metal objects | during thunderstorms a person should avoid touching objects made of this |
| snow storms | these can form when a large amount of humid air cools to below 0°C |
| flash floods | sudden violent floods which occur within hours or minutes |
| temperature ranges | these are often represented using different colors on a newspaper weather map |
| cold front | fast-moving front which often brings thunderstorms followed by clear skies |
| evacuate | best safety method when a hurricane is approaching is to leave your home or this |
| continental climate | climate of an area far from the ocean could be this |
| dry and clear | type of weather associated with an anticyclone |
| floods | when a river overflows its banks this occurs |
| meteorologists | scientist who study causes of weather and attempt to predict it |
| hurricane | type of storm which begins over the ocean and is long lasting with winds 119km or higher |
| fronts | weather maps use symbols of triangles and half circles to represent these |
| ocean currents | streams of water either warm or cool which can affect the nearby land temperature |
| temperate zones | climate zones which are located between polar and tropical zones |
| leeward | side of the mountain located in a rain shadow |
| altitude | mountains have a cool climate all year because this is also high |
| Northern Hemisphere | this hemisphere receives fewer direct rays from the sun in January than in July |
| cold front | front represented with triangles on a weather map |
| warm front | front represented with half circles on a weather map |
| stationary front | front represented with triangle on one side and half circles on the other side on a weather map |
| occluded front | front represented with triangle and half circles on the same side on a weather map |
| maritime tropical | type of air mass which comes from the Gulf of Mexico |
| continental polar | type of air mass which comes from Canada |
| continental polar | cP |
| maritime polar | mP |
| continental tropical | cT |
| maritime tropical | mT |
| mT | warm moist air mass |
| mP | cool moist air mass |
| cT | warm dry air mass |
| cP | cool dry air mass |
| Mid-United States | area most likely where a tornado would form in the US |
| arid or semiarid | type of climate found in a rain shadow |
| front | area where two air masses of different temperatures meet and do not mix |
| cold air mass | which temperature air mass is more dense |
| cold front | front associated with violent thunderstorms |
| warm front | front often bringing humid conditions such as rain or snow |
| cold front | fast moving front |
| warm front | slow moving front |
