Question | Answer |
air mass | large body of air that has the same characteristice of tempeture and moisture content as the part of earths surface over which it formed. |
blizzard | winter storm that lasts at least three hours with temperatures of -12degrees C or below, poor visibility and winds of atleast 51km/h |
dew point | temperatures at which air is saturated and condensation forms |
fog | a stratus cloud that forms when air is cooled to its dew point near the ground |
front | boundary between two air masses with different temperatures, density or moisture;can be cold, warm, occluded, and stationary |
humidity | amount of water vapor held in the air |
hurricane | large, severe storms that forms over tropical oceans, has winds atleast 120/km/h, and loses power when it reaches land |
isobar | is a line drawn to connect points of equal atmospheric pressure |
isotherm | a line that connects points of equal temperature |
meteorologist | studies weather and uses information from doppler radar, weather satellites computers and other instruments to make weather maps and provide forcasts |
precipitation | water falling from clouds- including rain, snow, sleet, and hail whose form is determined by air temperature |
relative humidity | is the measure of the amount of water vapor present in the air compared to the amount needed for saturation at a specific temperature |
station model | indicates weather conditions at a specific location, using a combination of symbols on a map |
weather | state of the atmosphere at a specific time and place, determined by factors including air pressure, amount of moisture in the air temperature and wind |
tornado | violent whirling wind that crosses land in a narrow path and can result from wind shears inside a thunderhead |
