8.4 Weather maps and weather prediction
air temperature, humidity, wind direction, wind speed, clouds, precipitation, atmospheric pressure, visibility
8 elements of weather
true
True or False: two types of weather maps that meteorologists use to show the weather are surface weather maps and upper-air charts
False
True or False: weather balloons and aircraft allow for surface weather observations
lines of equal pressure
What do the curved concentric lines on weather forecast maps show?
radar
____ works by bouncing radio waves off prescription; provides data on intensity and direction of a storm
aircraft
_____ can carry a variety of weather sensing instruments and collects data in places far from ground stations, such as over oceans; used to collect weather at mid to upper levels of the atmosphere
station model
a set of meteorological symbols that represent the weather at a particular observing station/ a small circle surrounded by a set of symbols and numbers that represent current weather data at a specific site.
develop a plan and continue to listen to the radio
as you listen to the radio, you hear an announcement for a severe weather watch. What shuold you do upon hearing this announcement?
long-range forecasts
can range from weeks to months into the future; can predict if the weather will be warmer or colder or wetter or drier than average, but not the temperature ad rainfall on a particular day
weather balloon
carries a small instrument package called a radiosonde; used to collect weather at mid to upper levels of the atmosphere
Doppler radar
important for detecting and tracking sever storms and tornades
weather watch
issued when severe weather conditions are possible over a large area; people should have a plan of action in case of a storm
weather advisory
issued when the expected weather conditions will not be a serious hazard, but may cause inconvenience
weather warning
issued when weather conditions that pose a threat to life and property are happening or are to happen
automated surface station
land-based ground station that collects weather data from the lower atmosphere 24 hours a day
Isobars
lines that connect points of equal air pressure used to show air pressure; marked in units called millibars
short-range weather forecasts
makes predictions 0-3 days into the future (0-72 hours)
medium range forecasts
predicts 3-7 days into the future (72-168 hours) temperature, wind, cloud cover, and precipitation are predicted iwth different degree of accuracy
orbiting weather satellites
provides data on water vapor, cloud-top temperatures, and the movement of weather systemns
cold fronts
shown using blue lines and blue triangles
warm fronts
shown using red lines and red half-circles
Weather forecasting
studying data to predict likely future weather conditions
meteorology
the study of weather and earth's atmosphere
true
true or false: 3 types of hazardous weather forecasts are weather advisories, weather watches, and weather warnings
upper-air chart
used to analyze weather based on the data collected by weather balloons; shows wind and air pressure at middle and upper levels of Earth's atmosphere
dropsonde
used to measure temperature, humidity, wind speed and air pressure
surface weather maps
used to show forecasts; displays air pressure and the locations of fronts
tornado warning
what kind of hazardous weather forecasts would the NWS issue if a tornado has been spotted and may be headed in your direction?
