3.4 Guided Notes Weather Forecasters Use Advanced Technologies
Weather data come from many sources
A ___________________________________ is a scientist who studies weather. In order to predict the weather,
meteorologists look at ___________________ and _____________________ conditions. They use many forms of
technology to gather data.
Instruments that gather weather data use many technologies and can be found in many places.
___________________________ locate clouds and measure their heights. ___________________, a special type of
equipment, can detect air motion and precipitation.
______________________________ orbit Earth above the atmosphere. Images can show cloud cover, warm and
cool regions, and invisible water vapor.
___________________________ and ___________________________ can carry instrument packages that make
measurements wherever they go.
_________________________________________________make important measurements of the air at different
altitudes as they carry instruments high into the stratosphere.
_____________________________________hold instruments that measure air pressure, temperature, dew point,
precipitation, wind speed, wind direction, and cloud cover.
______________________________________ record the weather far from cities. They also measure conditions in
the ocean that affect the atmosphere.
Weather data can be displayed on maps
Scientists use _______________________ to record and use the enormous amount of data gathered. One way to
make the information easier to understand is to show it on _________________________.
A single map can show many different types of data together to give a more complete picture of the
___________________________.
_________________________________ are used to combine information from many ground stations. The resulting
calculations give the ___________________________, __________________________ and
___________________________ that are marked on the map.
Air Pressure on Weather Maps
An ____________________ is a line that connects places that have the same air pressure. Each
________________________ is labeled with the air pressure for that whole line in units called millibars. A
_____________________________ number means a ____________________ air pressure.
Satellite Images and Special Maps
___________________take different types of images from space. Some images take
_________________________________ that reflect of the clouds and Earth’s surface. Another image shows
__________________________ given off by the warm surface and cooler clouds. These
____________________________________ can show cloud patterns even at night because objects with different
___________________________show up differently. ________________________________ change with altitude,
so infrared images also show which clouds are _________________ and which are ___________________ or tall.
Forecasters use computer models to predict weather.
_________________________ have become an important tool for forecasters weather. When
__________________________send in data, computers can create ____________________right away.
___________________________________________ combine many types of ________________________ to
forecast what might happen next.
